Description

Field of the invention

The present invention relates to a tester for various types of devices, devices or components, i. that is, a device used to measure a device's, device, or component's payload and then analyze the parameters derived from the test. More particularly, this invention relates to a tester for distributed function apparatuses, devices, or components wherein a simplified tester measures basic parameters of a device, device, or component and uses this raw data to analyze, manipulate, and evaluate the test results to determine the state of the device Device or component and optionally for relaying the raw data or the status data to another destination, for example from the smart device of a car dealer's technician to the customer service manager's computer, to a separate smart device such as a smart phone or a tablet computer which is otherwise usable transmits.

In another embodiment, the smart device may capture the fundamental parameters from the simplified test device and transmit the fundamental parameters and optionally other information for analysis, manipulation and evaluation of the test results for determining the state of the device to a web server.

The tester of the invention is described herein in detail with respect to a battery tester, but is not limited thereto as mentioned above. In this embodiment, a simplified battery tester is connected to the terminals of a battery to perform certain tests, and then outputs the resulting raw data for analysis, for example, a comparison of measured parameters of the battery with values expected from a battery in good condition and another appropriate action to a smart device.

Background of the invention

Batteries have been commonly used in many applications for years to provide electrical power needed for a wide range of applications. For example, batteries are widely used in the automotive industry to supply power to a starter for starting an internal combustion engine, to supply additional loads in a vehicle with power, and to supply electricity to electric motors that supply the driving force to the vehicle. Batteries are also used in many commercial applications for powering indoor vehicles or providing backup or standby power to a device such as a computer or telecommunications device in the event of a power outage.

Due to the ubiquitous use of batteries in so many applications, it is important to know the state of preservation of the battery so as to ensure the reliability of the primary application. In the past 50 years, a number of battery testing and monitoring methods have been developed to provide important information regarding a battery life condition. The simplest methods involve measuring the relative density of the electrolyte or measuring a voltage as well as a voltage under a given load. Measurements of a voltage under a load are evaluated by the device or by the user of the device to determine the state of conservation of the battery.

These methods have been largely replaced in the past 30 years by electrical test methods, commonly referred to as "resistive" test methods, where the internal resistance of the battery is measured and compared to a reference value. Exemplary ohmic battery test methods are in U.S. Patents 6,704,629 and 7, 212,006 from Huang, 5,744,962 for Alber, 3,873,911 described for Champlin and many others.

In general, it is considered that these ohmic test methods more efficiently and reliably indicate a state of battery preservation as compared with conventional load test methods or test methods based on the specific gravity. Ohmic test devices, however, are generally relatively expensive compared to the devices required for conventional test methods.

Furthermore, commercial ohmic test equipment is "integrated", i. h., they have both the measuring and the analysis function. Such integrated battery testers are provided, for example, with test terminals to be connected to the battery so that raw data parameters can be measured, and are further provided with a keypad or the like by which the user inputs multiple data inputs with respect to the specifications of a battery to be tested can, as well as with a microprocessor, a memory, a stored program and the like, so that the parameters can be analyzed properly and the user a useful result is provided.

The data inputs in a battery test are referred to herein as "context parameters". Entering these context parameters into the tester is necessary so that the measured parameters of a particular battery to be tested can reasonably be compared to nominal specifications of a similar battery in good condition. The context parameters are used to select a suitable algorithm for calculating a battery conservation state and a battery state with sufficient accuracy. Without such context parameters, the readings derived from a battery are not sufficient to determine a battery life condition or a battery condition.

For example, ohmic test equipment typically performs a measurement of "open circuit voltage" (OCV), that is, the voltage across the battery when no external loads are connected. Suppose an OCV of 6.4V is measured. If the rated operating voltage of the battery is not known, it is impossible to determine if an OCV of 6.4V indicates a good or a bad battery or a charged or discharged battery. If the device (or the user) knows that the battery should have a voltage of 12.6V at full charge, an OCV of 6.4V indicates that the battery is substantially discharged and may be defective. However, if the battery context parameters indicate that the battery is nominally a 6V battery, an OCV of 6.4V indicates that it can be considered fully charged. (It will be apparent to those skilled in the art that this is not enough to ensure that the battery is in good condition, only that it is fully charged. Additional measurements and context information are needed to determine the condition of the battery.)

In an ohmic test to determine the condition of a battery, certain context parameters must be used to determine a qualitative test result from the raw data measured by the tester. Such battery context parameters may include, for example, a nominal battery voltage or an expected battery voltage, a nominal battery capacity or a rated battery power, a battery power system, a battery type, a nominal battery size, a battery manufacturer, a battery chemistry, a battery age, a battery temperature, a battery pack configuration, a battery location, a checkpoint location, a port type, a connection material, a battery model, etc. include. In existing commercial battery testers, such context parameters are typically determined by the user, and appropriate values are entered into the tester in turn.

More specifically, depending on the testing application, more or less critical context parameters must be entered by the user before a test can be performed and qualitative results determined. This requires the tester to have a user interface for entering these values. The user interface of the typical integrated battery tester is any display screen associated with a keyboard, keypad, or number of buttons that the user presses in order to enter or select values, typically in response to prompts displayed by the screen. Through this interface, the user selects appropriate context values for the exam, initiates the exam, and performs actions after the exam, such as viewing exam results and printing or storing the results. The user interfaces provided in currently available battery testers are typically cumbersome and require a high number of button presses, so a large amount of time is needed to service them. Further, currently used user interfaces may be difficult to operate without instructions. Both can lead to operator errors and the omission of critical context information.

In particular, the process for determining and entering context parameters in a battery tester is fraught with errors and uncertainty. When prompted to enter battery context parameters, the user must understand which parameters are needed. The user must be able to determine these parameters by looking at the battery or otherwise available information. The user must enter the parameters accurately and completely. Often, there is not enough information about the battery available for the user to determine the basic and critical context parameters. This problem is especially pronounced in the case of AGM batteries (Absorbed Glass-Mat batteries). The electrical performance characteristics, particularly ohmic behavior, of AGM batteries can vary significantly from model to model and from manufacturer to manufacturer. Accurate ohmic testing of AGM batteries is based on a precise and precise understanding of the particular ohmic context parameters for the battery model. However, such information is not provided on the label of the battery. Additionally, even if the ohmic characteristics were known for a particular battery model, the same battery model can be sold under many different names, so that it is virtually impossible to determine the origin and appropriate context parameters for the battery because the battery does not sufficiently identify can be.

In practice, due to the difficulty of accurately and specifically identifying batteries, context parameters are often generalized so that broad categories of batteries are grouped together and a general context parameter setting is used for the entire category. For example, the contextual parameter "Battery Construction Type" has been generalized to include three basic (and visually identifiable) groups of batteries, referred to as WET, AGM FLAT and AGM Spiral. The user will select the closest of these battery type groups based on the visual inspection of the battery. However, the ultimate accuracy of the analysis is severely limited since each battery has certain battery type characteristics which, if correctly identified, could be used to determine a much more accurate battery check result. Ideally, a unique design parameter would be provided for each battery model, reflecting the very specific characteristics of the battery.

However, identifying specific battery type characteristics is very difficult. It is not practical or easy for battery manufacturers to specify specific battery type details on the battery label. Instead, only general specifications of interest to the buyer are indicated on the label. In addition, the same battery is often sold under different brand names unrelated to the original manufacturer, so that identification of specific battery characteristics by viewing the label is practically impossible. Furthermore, as mentioned above, even if the exact context parameters are identifiable by the user, the entry of this information into the tester is critical and is often done incorrectly. Often, the technician using the tester does not enter the information properly, so one or more context parameters are overlooked or entered incorrectly. An incomplete or incorrect input of context parameters leads to incorrect test results.

After entering the context parameters into the battery tester, the user initiates a battery test. The tester will measure certain raw data parameters of the battery. Typically, only two or three raw parameters are measured, such as voltage and resistance, and occasionally the temperature. However, many other parameters are measurable and potentially useful in determining the state of preservation of the battery, including capacitance, reactance, inductance, fluid level, electrolyte specific gravity, current, etc., and accordingly are intended to fall within the scope of the invention. These measured raw parameters are then used in complex algorithms to determine qualitative results as a function of the input context parameters. These qualitative results indicate the state of the battery and may include, for example, estimated cold-start power, a state of charge, a health state, a remaining battery life, a starter state, and other quantities. The determined qualitative values are then compared with the context parameters entered by the user to arrive at a conclusion, typically passed or deficient. These calculations are performed using a microprocessor and usually displayed on the screen of the user interface, and they can be printed out for future use or stored in the memory of the device. In the context of vehicle batteries, it is also known to start the engine of the vehicle and measure the minimum voltage across the battery during cranking, indicating a battery maintained condition, and to measure the voltage and current ripple after starting the engine, which is a generator power indicates.

In more complex battery testing environments, such as when testing a parallel pack of batteries, or when testing and comparing multiple batteries in a series of batteries, the hardware and firmware of the tester must have a long and complex test sequence; For example, instructing the user to perform multiple steps, and then saving and comparing qualitative and quantitative results of multiple tests.

As the testing of batteries has evolved and the results of battery testing become more important in improving quality and handling battery warranty, it is desirable to be able to obtain the test reports or test records from the tester so that they can be collected and further analyzed or distributed, or combined with other information, for example, to provide operational reports. This storage and exchange of information is often cumbersome and expensive. Typically, this capability requires memory as part of the device, so that a large number of test records can be stored, along with an interface that allows the files stored by the device to be transferred to another device, such as a computer system Tracking data for a vehicle fleet. Procedure for transferring stored data to another Devices include the use of removable memory cards or on-board memory which can be read by a data port such as a serial port or a "USB" port connected to a computer. Alternative methods include a "WiFi", "Bluetooth" or other radio or infrared connection between the tester and a remote device so that test reports can be sent to a network.

Thus, it can be seen that, even though the function of a battery tester per se is comparatively simple, since only a few raw data parameters can be determined from the battery itself, commercially available battery testers have become complex and expensive to provide useful qualitative results Indicate battery condition and provide executable recommendations for a wide variety of battery types, and also provide the ability to back up and exchange results and reports, print results, send results to a remote device for further analysis, and the like.

Similar problems arise in other forms of specialized integrated test equipment, such as a specialized device for reading diagnostic data from an on-board diagnostics port (OBD port) of a car, a device for verifying proper performance of telecommunications equipment, and many other devices. More specifically, there are numerous examples of testers of various types, including actually collecting data, downloading status codes, performing simple checks, and the like, as compared to analyzing the test results, receiving required context data, providing a user interface, passing the results of other devices and the like is a simple task.

Objects and Summary of the Invention

Therefore, it is an object of this invention to provide a low cost, simplified apparatus for testing devices, devices or components, i. H. for measuring relevant parameters of the devices, devices or components, and for transmitting the measured values to an associated external "smart device" which may also be used for other purposes, for example a smart phone, a tablet computer or the like. In this way, the device-specific test device can be considerably simplified, and already existing capabilities of the smart device can be "exploited", i. H. additionally used.

The smart device may be configured with software for performing analysis of the test-derived parameters, or it may be configured with software to connect to a remote web server so that the web server performs the analysis based on the test derived parameters. A tester according to the invention thus comprises a simplified test apparatus, a suitably programmed smart apparatus and optionally a suitably programmed remotely connected web server.

In conjunction with the testing of a battery, the simplified battery tester measures the basic battery parameters of interest, typically an open circuit voltage, a resistance value of the internal resistance of the battery, and a temperature, and appropriately sends that raw data to the smart device for analysis, Evaluation, determination of results and further processing of test data. More specifically, in this way, the external smart device is provided with a memory, a user interface for acquiring battery check context information, and a circuit for displaying, storing and transmitting results and check reports instead of the battery check device.

The external smart device may also be used for other purposes, so that it does not serve solely the purpose of battery testing per se. More specifically, the external smart device may be a smartphone, a tablet computer, a laptop, or the like. Thus, splitting the function of the known battery tester to the simple, low cost battery tester and the existing external smart device according to the present invention has many advantages, which will be discussed in more detail below.

In summary, these advantages include a substantially reduced cost for the battery tester, since the test circuitry can be very simple, enabling entry of the context parameters by means of the sophisticated user interface already provided by the external smart device, which does this task for the user simplifies, enabling use of the memory and the computing power of the smart device to perform the analysis of the raw data and enabling use of the sophisticated communication capabilities of the smart device to provide convenient passing test results to a remote device. Furthermore, according to the invention, that contained in such smart devices Image sensor can also be used for several purposes, which will be explained in more detail below.

As mentioned above, the test devices of the invention can be used in applications other than battery testing per se, in other words, in a distribution of the data measurement function and analysis function to a simplified test device and an existing smart device capable of others Perform tasks that allows a "benefit" of the capabilities of the smart device, which are generally much more sophisticated than in known integrated test equipment. This, for example, allows a technician, who will typically have a smart device for personal and business use, to use this device along with one or more simplified test devices, each for easily obtaining useful raw data from a variety of different devices, devices or components are used.

For example, it can be readily imagined that an auto mechanic would like to have a simplified battery tester and a different simplified device for connection to the "on-board diagnostic port" (OBD port) for downloading various data objects used in verifying vehicle operation It is useful to track defects that are provided on modern vehicles (or to be equipped with them). Both devices would read raw data and transfer it to a smart device for analysis. With this device and a smart device, the mechanic could avoid having to buy a separate integrated battery tester and an OBD tester, which essentially saves the cost of the tools needed. Further, the smart device would be useful for all the purposes in which such devices are used, both for personal purposes and for business purposes, so that the cost of the smart device would not burden the mechanic's budget for tools.

Referring again to an embodiment of the invention in which the simplified test apparatus is for battery testing (however, remembering that the invention is not so limited), the objects and advantages of the invention will be further explained, it being understood that many of these objects and advantages are not limited to battery testing, but may be useful in testing various devices, devices, and components:
It is an object of this invention to adapt the user interface, the processor, the memory, the image sensor, the communication device, the ability to conveniently download software that adapt the smart device for analysis of data provided by various simplified test devices, and other components and capabilities of an external smart device instead of the battery check circuit, for example, for interacting with the user, acquiring battery context information, calculating qualitative results, and managing results, thereby reducing the expense and complexity of the particular battery tester provided.

It is another object of this invention to provide the user interface, the image sensor, the communication device, and the processing device of a portable device such as a smartphone or a tablet computer to perform tasks of accepting user-inputted battery context information, executing algorithms for calculating qualitative battery check results, and displaying and / or transferring these results, thereby avoiding the hassle and complexity of providing user interfaces, keyboards, communication systems, memory, and other items in a dedicated battery tester, as is required in known integrated battery testers.

It is a further object of this invention to provide a simplified battery tester that measures basic battery levels and passes this information to a remote smart device. The remote smart device is provided with software that prompts the user to enter context information and guides the user through a series of actions and inputs to complete a qualitative analysis of the battery. The remote smart device is configured to execute many different software programs, each program being tailored to the analysis of a particular battery type or battery application. The software of the remote device is designed so that the software can be updated at any time to improve or modify the analysis algorithm, e.g. By a conventional software download, so that the simplified battery tester need not have the capability of being updated to provide better results.

The remote smart device may also access data for improving or modifying the checking algorithm by updating the locally stored list of critical algorithm parameters so that no software update is needed, only an adaptation of critical logic values. Such an update can done by a simple interaction with a suitably configured web server.

In accordance with another aspect of the invention, a simplified battery tester measures basic battery values ("raw data") and passes this information to a remote smart device as set forth above. The remote smart device is again configured with software that prompts the user to enter appropriate context information. Such context information (eg, battery model, make, size, type, standard power, voltage, unique ID) may be input manually from information on the battery label, or the software may be used to use the camera or other digital sensor or receiver to acquire a battery identification code ( UPC code, bar code or other proprietary code). It is also contemplated that batteries may include a radio identification (RFID) chip that transmits battery identification data when activated by an associated RFID receiver included in the simplified battery tester.

In another embodiment of the invention, after receiving the raw data and the context information or a battery identification code by the smart device, the smart device communicates this collection of raw data and context information or battery identification code to a remote web server. When the raw data is accompanied by context information, an algorithm for determining the state of the battery based on the raw battery data and the context information is executed on the web server. Alternatively, when the raw battery data is accompanied by a battery identification code, a program configured to retrieve battery context information for the battery from a database is executed on the web server, and thereafter, the algorithm for determining the state of the battery is executed.

According to a particular advantage of this latter aspect of the invention, the smart device need not be configured with a particular analysis algorithm, as this function is taken over by the software on the web server. The appropriate analysis software runs on the web server and returns the result data for presentation to the smart device for the user. In this way, the software on the smart device can be kept simple and focused only on collecting information and providing a user interface, while the web server application is responsible for executing the appropriate algorithms. In this embodiment, the simplified tester provides raw battery data, the smart device provides a user interface for the collection of context and other test information from the user, and the web server software performs all the analysis and diagnostic tasks. In this way, the cost and complexity of maintaining and improving the diagnostic algorithm is reduced since software on the smart device need not be modified or updated; all updates, eg. G., The appearance of new types of batteries are performed simply by updating the databases accessed by the web server. Further, the fact that the software application program ("App") running on the smart device can be greatly simplified so that it essentially serves only to communicate data from the simplified battery tester to the web server, which makes it easier to enable use of different types of smart devices in the implementation of the invention.

In another modification, the simplified battery tester measures basic battery levels and passes this raw data to a smart device. The smart device is configured with software, for example, commonly known as a web browser, or other similar software that interfaces with a specific remote web server. In this embodiment, the smart device simply forwards the raw data to the server, and the web server responds by representing a "web form" for the browser of the smart device. The smart device then prompts the user to enter context information needed for a complete analysis. Thus, the remote web server is configured with software that causes the smart device to display one or more forms that prompt the user to enter appropriate context information, and after completing the form or forms, the web server performs the analysis using the raw battery data and the context data provided by the user. In this embodiment of the invention, the smart device need only be configured with basic "web browser" software for providing a connection to the web server; no dedicated application ("app") needs to be provided on the smart device.

In another embodiment of the invention, a simplified battery tester measures basic battery levels and displays these values in human readable form. The user can then simply transfer the raw data into a conventional web browser (ie, on a conventional PC) adapted to accept the input of basic battery values and context data. The web browser then delivers this information to a remote web server. The web server software is adapted to apply the appropriate algorithms to the input data and return the test results to the browser. In this way, it is possible to completely bypass the smart device.

A particular advantage of the present invention is that the simplified test apparatus only produces raw data, so it is very unlikely that there is a need to update its capabilities, for example, as new types of batteries become available. Accordingly, the simplified tester should be able to be used for many years, even as new types of batteries become available and must be tested. When the analysis of the raw data is performed by the smart device, new methods, algorithms, battery applications, and context information properties can be transferred to the smart device through a simple software download and integrated into final qualitative results; if the analysis is being performed by a web server, all it takes is to update the software on the web server, in both cases the simplified tester need not be modified. Such changes can be made quickly and easily to the software residing on the remote smart device or on the web server simply by updating the appropriate application software. This method significantly increases the range of battery types, battery configurations, and battery applications that can be tested using the same simplified battery tester.

According to another aspect of the invention, a battery tester communicates raw data to a smart device, and the smart device acquires battery identification information directly from the battery that can be used to reliably identify the specific battery model without the user reading and understanding information on the battery label must and must enter this information. Using the battery identification information, specific context values important to accurate battery testing are accessed in a database and provided to the analysis and diagnostic algorithm. In this way, the battery tester and smart device can be used to test batteries without the user having to enter data. This simplifies operation of the tester and eliminates a common source of error.

It is another object of this invention to provide a simplified battery testing apparatus that rapidly and conveniently communicates raw information relative to an objective battery parameter to a remote smart device using a simple, low cost method. This simple, low-cost communication between the simplified battery tester and the smart device can be performed in a variety of ways, each known from other fields.

For example, the battery parameter routing information may be transmitted quickly and conveniently from a simple tester to a remote device by a wired communication technique, such as serial communication, performed using the known USB communication technique. Alternatively, the battery parameter routing information can be quickly and conveniently transferred from a simplified tester to a remote device using a wireless communication interface such as the known "WiFi" or "Bluetooth" wireless communication technology. Such wired and wireless communication techniques are supported by the smart devices used today and can be readily implemented in a simple battery tester.

However, both wired and wireless communication technology is subject to certain potential complications; Wired cables may be lost or damaged, and WiFi or Bluetooth standards may change over time. If these complications could be prevented by a simpler communication technique, noting in particular that there is no particular reason for communication from the smart device to the simplified battery tester, but only for communication in the opposite direction, another advantage would be obtained become.

Therefore, it is another object of this invention to provide a method for transferring battery parameter information from a simplified battery tester to a remote smart device in a rapid and convenient manner while avoiding a wired data or communication bus or a radio transmission method. Such a method allows one with a very low cost connected and with few problems battery tester.

According to this latter aspect of the invention, battery parameter routing information is transmitted from a simplified battery tester to a smart device by allowing the simplified tester to display a graphical image, such as a bitmap image, that is visually recognized by a smart device. Since the conventional smart devices nowadays all contain an image sensor and are capable of employing sophisticated software for recognizing such bitmaps and reading data therefrom, provision of communication from the simplified battery tester to the smart device relies on them Do not complicate the functions already provided by the smart device; the battery tester need only be able to display a bitmap containing the raw data in a form that can be recognized by the smart device, which is easily possible.

One known form of such bitmaps is known in the industry as the "QR" code conventionally used to transfer characters from, for example, a journal to a smart device. For example, a user may cause the camera of his or her smartphone to scan a QR code in an advertisement in a journal. The QR code usually stores an Internet address, which can then be used by the smartphone immediately to access the website of the person who posted the ad. Such QR codes can be readily generated to encode raw data, for example measurements made with respect to a battery under test, and be displayed on a screen of a simplified battery tester and read therefrom by the smart device. Therefore, it is an object of this invention to provide a means and method for rapidly and conveniently transmitting battery parameter information from a simplified battery tester by allowing the simplified tester to display a QR code containing the battery parameter information. The QR code is visually detected by an image sensor or a camera of the remote smart device. The smart device then uses the raw data transmitted by the QR code and the battery context information entered by the operator to evaluate the battery in the manner previously described.

It is also within the scope of the invention that multiple sets of raw data are collected and transferred in separate operations from the simplified battery tester to the smart device. For example, the simplified battery tester may measure a voltage, a temperature, and a resistance, and display a QR code having these three values and then wait for a startup sequence of an internal combustion engine. When a starting sequence of an internal combustion engine is detected, it will detect the starting voltage (that is, the minimum voltage reached by the battery during starting of the internal combustion engine), a generator voltage, and a generator ripple. After collecting these values, it will generate and display a new QR code containing these additional values. The smart device will receive the QR codes in turn, analyze the data and display the qualitative result.

It is also within the scope of this invention for the simplified battery tester to display a QR code, wherein the battery parameter data information is associated with address information such as an Internet address or a specific Internet Protocol (IP) address such that a smart device or other application that receives this code that can pass all information directly to a specific web server configured to analyze the connected battery parameter data. An example string could be " http://www.testdata.com/?/Xb342C12a5d2h331x4f " be. In this example, www.testdata.com is the address for the web server where the diagnostic software resides, and the following string contains some or all of the data necessary to determine a diagnostic result. Using this method avoids the need for the smart device to contain the diagnostic software. Instead, the smart device only needs to be able to pass the test data string to the web server and display results returned by the web server.

It is desirable to prevent unauthorized software applications from using the measurements produced by the simplified battery tester - that is, it is desirable to prevent unauthorized vendors from selling software for smart devices that interact functionally with the smart device simplified battery testing device of this invention allows. Accordingly, it is a further object of this invention to provide the battery parameter information after encrypting the battery parameter information into a series of values that do not directly reflect battery measurements, and then converting those encrypted values into a graphical image that is remote from one Device can be scanned from a simplified battery tester to a remote smart device. In this embodiment of the invention, the remote smart device includes software capable of decrypting the data so that the values can be analyzed as a function of battery context information and used to determine qualitative battery performance information.

In another embodiment of the invention, existing wiring interfaces in a vehicle may be used to minimize the number of connections that must be made between the battery being tested and the smart device. One such method is to use the existing DC power cabling in the vehicle to relay the raw battery parameter information. By using the existing power wiring in the vehicle, the battery tester connected to the battery, which is also connected to the wiring of the vehicle, can transmit the raw battery parameter information using one of many possible protocols via the vehicle DC wiring. A receiving device connected to the DC power cabling remote from the battery tester may then receive the battery parameter information communicated via the DC cabling.

More specifically, modern vehicles all have an on-board diagnostic port (OBD port). An "OBD scan tool" is connected to the OBD port by a technician to detect vehicle operation data, error codes, and the like. The OBD port connectors include the DC power wires (B + and ground) and are thus directly connected to the battery. The simplified battery tester may be connected to the battery, perform the desired test, and then transmit the raw data to the OBD port via the power cabling. A typical OBD scan tool may be configured to receive the raw data. In this way, the raw battery parameters may be transmitted to a remote device by the appropriately configured OBD scan tool using one of many communication methods already used by OBD readers. Such methods include Bluetooth, WiFi, and direct wired communication, but could also include displaying an optical code described above.

It is an object of this invention to improve the accuracy and reliability of battery measurements by repeatedly measuring one or more battery characteristics automatically and automatically comparing results to ensure that the measurements are consistent within an acceptable range. If the results are consistent within an acceptable range, the values of the sequentially measured results may be automatically averaged to produce an average or otherwise statistically modified to produce a result that best reflects the true measurement. If the successive results are not sufficiently consistent, then the simplified battery tester will automatically measure the property n more times, where n could be any value greater than or equal to one, and the results are further analyzed for consistency. If the results are not sufficiently consistent, the tester can clearly display on the display a failed test or generate a graphical code which, when scanned from a remote device, indicates a failed test so that the user can initiate a new test ,

It is an object of this invention to quickly, conveniently and accurately sense battery context information on the smart device so that the software of the smart device can accurately process the raw data from the simplified battery tester without the user of the tester or smart device evaluate or enter certain context information. This will allow for automatic digital input of battery characteristics and context information so that operator errors as well as input of battery test data are eliminated. This data is captured digitally by using RFID, optical scanning or other digital techniques to eliminate potential operator errors and reduce overall test time.

In one embodiment, a software application running on the smart device prompts the operator to direct the image sensor at a bar code on the battery label. The image sensor detects the bar code image, and the software determines the battery identification information based on the code number. Once the battery identification information is known, generic or specific battery context parameters may be retrieved from a local database stored on the smart device and containing a long list of battery identities and their associated context parameters or from a remote server maintaining such a database. be downloaded and used in the analysis of the battery under test.

The battery identification information may simply be the well-known universal product code (UPC) or some other dedicated code, which can be optically read by the smart device. Alternatively, the battery identification information may be stored digitally and transmitted and detected as a radio code, e.g. Using known radio frequency identification (RFID) techniques. For example, the battery manufacturer may use an "RFID chip" in the battery during manufacture, and the battery ID may be received by an RFID receiver in the simplified battery tester and transmitted to the smart device by one of the methods described above.

The battery identification information allows the battery to be identified as a specific battery model. As previously mentioned, in known battery testing methods, the battery model information is generally associated with one of a few battery types, referred to as a battery design or battery design, such as wet, maintenance free, Absorbed Glass Mat (AGM), gel cell, etc. Each battery type is one or more generic Associated with conversion characteristics used by the analysis algorithm to convert raw battery information into generally understandable battery power metrics such as cold cranking current (CCA), starting current (CA), or ampere-hours (Ah).

However, for all battery types, especially for AGM batteries, the generic conversion characteristics are only approximations and are inherently inaccurate compared to a specific conversion characteristic for a particular battery model.

In one embodiment, the smart device is configured to contain specific contextual details, including diagnostic algorithm details, and specific conversion characteristics or battery types for specific battery models. Once the specific battery model is known, the specific battery context details may be used to determine the test results. In this way, the specific battery testing algorithm can be tailored very accurately to the specific battery model under test, which improves diagnostic accuracy.

Specific battery context details for a battery model may include items such as customized battery types, reference power values based on one or more test standards, a battery mark, a battery model name and a battery number, a battery design, a warranty period, parameters in Berg to an expected end of life, and any other information about Include battery models that could be useful in assessing the performance and health of a battery.

If the battery is configured with a code uniquely associated with a specific battery, such as a serial number, additional identification information may be determined from the serial number. For example, the serial number may be visually scanned and disassembled into components that may include a battery mark, a battery model, a unique battery ID, a manufacturing date, a date of origin, an originating factory, or any other data encoded by the battery manufacturer in the code are. The software of the smart device may determine the specific information contained in the code, or the software of the smart device may be configured to transmit the code to a web server for identifying the code type and determining the code specific information components and values are formed in the code based on the code type. The web server would then return the information to the smart device along with relevant specific battery test parameters to be used to analyze the battery.

In this way, battery manufacturers can maintain, modify and update the critical parameters and thresholds that are used to evaluate their batteries. By modifying the parameters in a database maintained on a web server, a subsequent check is made according to the updated parameters. This allows for a very efficient and rapid dissemination of settings and enhancements without having to update the firmware coded in most battery testers, and even avoids the relatively hassle-free process of updating the software on the smart device because the Updated parameters are used by the software of the smart device as soon as the master parameter database stored on the web server is updated.

It is a further object of this invention to quickly and conveniently add useful identification information to a test record so that the test report can be readily assigned to a particular battery, vehicle, facility, location, building, or other useful identification attribute can. This can be readily accomplished by adding such identification information using hardware and software already present on a remote smart device.

For example, in connection with a vehicle, the software on the remote smart device may prompt the user for identifying details by the remote smart device, either before or after scanning the display of the simplified battery test device for acquiring the simplified battery measurements To add battery or vehicle. The details could include the vehicle identification number (VIN) that can be optically scanned or photographed by the image sensor of the remote smart device and then stored in association with the battery state information for later use. In this regard, the scanned image of a human-readable version of the VIN may be converted by the software using optical character recognition into an alphanumeric string representing the vehicle identification number and stored as a field along with the other battery-related data becomes. Alternatively, the VIN may be present on the vehicle in the form of a bar code which may be scanned by the image sensor of a remote device and converted to alphanumeric code.

The VIN may be correlated to a specific vehicle manufacturer and a specific vehicle model using a database residing in the smart device or being accessed via the Internet on a web server. The manufacturer and model of a vehicle can be correlated with specific contextual details that can be used to improve the accuracy of the diagnosis. For example, the VIN may be used for determining the manufacturer-specified battery for a vehicle, and the reference values for that battery may be used as context information for the vehicle.

Such information regarding the characteristics of a specific vehicle may also be used to address another common problem. It is particularly difficult to test batteries that are in remote areas in the vehicle. Often, batteries are under a seat or in a remote area that is not easily accessible. In this case, remote battery connections are provided for starting up or enabling basic battery diagnostic procedures in a conveniently accessible location. Ohmic tests of a battery performed at the remote terminals, however, are corrupted by the resistance created by the connections between the battery and the remote terminals used for testing. If the resistance of the particular configuration is known, then an adjustment of the test results can be made to obtain an accurate diagnosis. A database of such adaptation factors for each vehicle can be generated, and when the VIN is scanned, the smart device or web server can look up and apply the appropriate adjustment factor to obtain a highly accurate inspection result.

Other useful identification information that can be similarly captured and stored with the test report includes a battery strobe code, a serial number or a part number, a photograph of the battery, the license plate number of the vehicle, the number of a vehicle associated with a vehicle fleet, location the test as determined by a GPS provided on the remote smart device, a photograph of the installation of the battery, or any other information that can be used to identify the battery being tested.

It is another object of the present invention to automatically integrate battery check report information with other maintenance information related to a particular vehicle during maintenance. After a simplified battery measurement information has been obtained by the remote smart device and converted to battery state information as a function of the context information, a battery test report is generated. This battery test report includes battery identification information that can be correlated with a particular vehicle or owner. By using one or more related identification values, the battery test report may be automatically combined with other records relating to the same vehicle, vehicle type or owner.

As previously mentioned, although described herein in the context of testing a battery, the invention may be applied to testing numerous forms of devices, devices, and components. In either case, a simplified testing device is connected to the device, device, or component to be tested, measuring raw data, collecting stored data, and similar operations for obtaining raw data used to determine the state of the device Device or the component can be analyzed, and transfer the raw data to an associated smart device. The smart device will then perform the analysis, typically after inputting contextual parameters that govern the normal operation of the device, device, or device Specify component, and provide a useful output. In this way, the cost of the test apparatus can be minimized, and the sophisticated analysis, display, user interface, image capture, data storage, software update, and communication capabilities of the smart device can be used in a variety of applications.

Other aspects and features of the invention will become apparent to those skilled in the art from the following description.

Detailed Description of the Preferred Embodiments

As previously mentioned, shows 1 an overall construction of a tester with distributed measurement and analysis function according to the invention. The tester is shown in connection with testing a vehicle battery, but the invention is not limited thereto, which will be explained in more detail below.

As previously mentioned, the basic function of a measurement of battery parameters, typically open circuit voltage (OCV), resistance and temperature of a battery 10 , through a simplified battery tester 12 if done by connecting to the battery 10 "Started up" is. The technique used to measure the resistance may generally be the technique described in the aforementioned Huang patents and summarized below, but may be another technique. Other than the mentioned values can also be measured, as previously noted.

In a more complex test, after measuring the aforementioned basic parameters, the user may be prompted to start the vehicle's internal combustion engine. This will result in additional measurements, typically the minimum voltage measured across the battery during engine cranking, which is useful in evaluating the battery, and the voltage and frequency of ripple detected after the engine is started , which is useful in the evaluation of the generator or the alternator. The steps necessary to carry out these tests are described below with reference to 4 described.

After performing the of the simplified battery tester 12 supported tests in the manner described above then transmits the simplified battery tester 12 this battery parameter raw data to a smart device 14 what by the reference 16 is specified.

Such intelligent devices 14 , which typically include devices commonly known as smartphones or tablet computers, and also include other devices having the required capabilities, have several features employed in implementing the invention. For example, such smart devices include image sensors connected to image processing circuitry and software so that they can decode symbols such as a so-called QR code, yielding an alphanumeric string of letters and numbers. These smart devices are also provided with memory and significant processing power, having the ability to download software (commonly referred to as an "application" for the word "application") that adapts the device to a new use, and have the ability to communicate in several ways. Thus, in order to adapt an existing smart device for use in connection with the present invention, one merely has to download suitable software, for example software implementing the steps discussed below.

As previously mentioned, the raw data can be obtained in several ways from the simplified battery tester 12 to the smart device 14 including a wired connection or a radio connection. Currently, the preferred method is an indication of a coded version of the raw data on a screen 13 the battery tester 12 , z. B. in the form of a QR code (see two ), and reading it by an image sensor or camera in the smart device 14 is included. The smart device 14 which has been provided with battery context information such as the battery power (for example, by a user input via a touch screen 18 ), then analyzes the raw data according to a stored algorithm and determines the battery condition.

The smart device 14 can for optically detecting a bar code 27 or another code on the battery 10 , which includes battery identification information, may be formed. Alternatively, the smart device 14 use other methods to acquire battery identification information from the battery. For example (as in the following in connection with 6 discussed) may be the simplified tester 12 an RFID receiver capable of receiving information from an RFID chip supplied by the manufacturer as part of the battery 10 is provided. That of the RFID receiver in the simplified tester 12 received information may be transmitted to the smart device along with the battery check information in one of the manners described herein. Upon receipt of the battery identification information, the smart device is 14 being able to select specific battery context information for the particular battery under test. The smart device 14 may be equipped with a database of specific batteries and the corresponding context information for each of them, or the smart device 14 can pass the battery identification information to a remote web server, which with 30 where context information is available for that specific battery; the web server then provides the appropriate battery context information for calculation of battery condition results to the smart device 14 further.

Optionally, the smart device 14 the battery status data to a remote computer 20 transferred, for example, to the maintenance system of a dealer or a workshop. In that case, the smart device becomes 14 also prefers vehicle identification data such as the VIN generated by the smart device from the tag 22 , which is provided on all vehicles, can be read, which is indicated by the reference numeral 24 specified, or the license plate number 26 of the vehicle, also through the smart device 14 can be read, what by the reference 28 is transmitted. The battery status data and other identifications may alternatively or additionally be via a printer 25 be printed out.

As previously noted, the smart device becomes 14 typically require battery context information, typically including the battery type and rated specifications of the battery, as well as the battery performance type to which the specifications relate to perform the analysis. This information is usually printed on the label or sticker on the battery. The user can enter this information directly in response to prompts displayed on the screen of the smart device. Alternatively, the smart device may obtain this data by user input of a battery identifier such as the part number, whereupon the specification of the battery is downloaded from the internet, for example from the battery manufacturer's website, indicated by the reference numeral 30 is specified. The smart device 14 may also be capable of identifying the battery from a bar code, RFID storage device or similar identification 27 on the battery 10 read, if any, and also receives the nominal specification and other contextual information from a database residing on the web server, unless the relevant specifications are already included in the RFID info or bar code.

As previously mentioned, in most cases, batteries are grouped into major types of categories, such as "wet,""VRLA," or maintenance-free, and AGM, which share resistance. This was advantageous because the user can expect to determine the general type of a particular battery by inspecting it. The battery tester or in the case of this invention, the smart device 14 is typically provided with specific algorithms that are generally accurate enough to test each type of battery. However, it has been found that within one type category, especially the AGM type, there are differences in the ohmic behavior of batteries. When a specific battery can be tested using specific algorithms suitable for the model, the test accuracy is improved. By allowing the smart device to identify a specific battery as previously described, the smart device can download not only battery specifications but also certain algorithm parameters for that specific battery model. Downloadable information could also include a specific battery type factor, a battery guarantee duration, and other useful properties that are not readily ascertainable.

two shows a schematic view of the simplified battery tester 12 according to the invention. As shown, the device 12 a central unit 32 including the circuitry necessary to perform the described functions, which will be described below with reference to FIG 3 is discussed in more detail, an ad 13 and a positive and a negative spring clamp 34 and 36 for convenient attachment to the poles of a battery 10 , as in 1 is shown on. The clamps 34 and 36 are over cable 38 and 40 in a conventional manner with the internal circuitry of the device 12 connected. The clamps 34 and 36 and their associated cables 38 and 40 may be implemented as so-called Kelvin terminals, which are conventionally used, with separate conductors for signal level currents, such as the voltage across the battery 10 and stronger currents such as the current when a load resistor for measuring the internal resistance thereof is connected across the battery. See also the above-mentioned Huang patents. One of the clamps 34 and 36 can be a temperature sensor 42 for measuring the temperature of the battery 10 contain.

3 shows a block diagram of the components of the simplified battery tester 12 the invention. These include a microprocessor control unit (MCU) 44 , an ad 13 , Electric wire 38 and 40 that the MCU 44 with the battery 10 which is to be tested, connect, and a transistor switch 46 , As mentioned before, the cables can 38 and 40 each in Kelvin terminals 34 and 36 end up. When used for other types of testing, the MCU software becomes the test instrument 12 in terms of testing for a particular type of device, device or component, optimizing, storing and executing, and the tester will be provided with suitable connection components.

4 As previously mentioned, shows the basic steps of the process performed by the simplified battery tester 12 when connected to a battery. In step 50 becomes the device 12 connected; the process begins immediately upon such a "startup" of the tester 12 , As in 52 , there is an initial delay for a duration of N (eg, five) seconds so as to allow a transient response to decay, for example, to ensure that the terminals 34 and 36 good contact with the terminals of the battery 10 produce.

In step 54 leads the device 12 a number X of identical measurements of basic parameters of the battery 10 out. As previously discussed, these measurements will typically include an initial open circuit voltage (OCV) measurement across the battery. An "ohmic value" (resistance value) for the internal resistance r of a battery 10 can then be measured by measuring the voltage V _B (equivalent to OCV) across the battery using contacts 47 and 47 ' Connecting a load with a known resistance R across the battery for a short period of time by closing the switch 46 so that over contacts 43 and 43 ' a single short pulse of a large current I is taken from the battery, and measuring the voltage V _R across the load R using contacts 45 and 45 ' while again measuring the voltage V _B 'across the battery. The current I taken from the battery is then calculated by I = V _R / R, and the internal resistance r of the battery is calculated by r = V _B -V _B '/ I. See also the Huang patents mentioned above, it being understood that the invention is not so limited. The result indicates values for the OCV and the internal resistance; the temperature of the battery 10 can also be measured using a contact 42 , like already mentioned before.

As by the steps 56 . 58 and 60 indicated, the measuring step 54 Repeat X times to ensure accuracy.

If the measured battery parameter data thus determined are considered reliable, they can be used as in step 62 be specified and compressed as in step 64 stated be encrypted before going in step 68 be transmitted. Compression and encryption can consist of transforming the data measured in a decimal format into a different format, such as hexadecimal format. This causes the number of characters to be transmitted to be reduced, thereby providing a data compression function, and further, the transmitted data (eg, a QR code or the like) is more difficult to decode for an unauthorized user, providing an encryption function , More specifically, any smart device can read the QR code and obtain therefrom an alphanumeric string without specific knowledge of the algorithm needed to convert that string to data indicating the measured battery parameters, however, the alphanumeric string is per se useless. In addition to the battery parameter data, an identification of the simplified battery tester 12 be transferred, what in step 66 is specified. This would typically be the model and serial number of the device 12 and the software version that uses it.

When the battery testing apparatus of the invention is used for testing a battery used as a battery for starting an internal combustion engine, the user may be prompted to start the internal combustion engine at this point, or he may do so at the expiration of a few seconds by step 70 is specified. The tester 12 will then as in step 72 specify secondary measurements; As previously mentioned, these typically include the minimum voltage across the battery during start-up and the voltage and frequency of a ripple after starting. The former indicates the state of conservation of the battery, and the latter indicates a function of a generator.

After connecting these secondary measurements, the data obtained in the steps 74 and 76 as previously explained, compressed and encrypted, and both the primary and secondary data may be used in step 78 again preferred by generating a QR code on the screen 13 the tester 12 is displayed.

It will be appreciated that while a QR code is currently the preferred form of code for transferring data from the simplified tester to the smart device, other forms of machine-readable optical data transmission formats may be used and, accordingly, within the scope of the invention , For example, a one-dimensional code such as a bar code may be used, or other forms of two-dimensional "bitmaps" that are comparable to the QR code may be used. Accordingly, reference herein to the use of a QR code is intended to include other forms of code that are suitable for the purposes stated herein.

5 shows the main steps taken by the smart device 14 upon receiving the battery parameter raw data relating to a specific battery 10 To be tested, from the simplified battery tester 12 be received, analyzing the data with reference to context parameters describing the nominal characteristics of the battery, determining the battery condition and communicating the results in a useful form.

In the step 90 Assuming that the simplified battery tester is capable of displaying data on its screen in the form of a code, such as a QR code (possibly compressed and / or encrypted), the smart device scans 14 the QR code. As noted previously, all devices referred to herein as smart devices have the ability to scan QR codes and convert the QR codes into an alphanumeric string (if the corresponding app has been downloaded). This will be in the step 92 carried out. When the raw data has been compressed and / or encrypted, the smart device becomes 14 as part of the app that enables the device to function in accordance with the invention, have downloaded software needed to convert the QR-encoded data into a series of measurements.

In step 94 represents the user of the smart device 14 provide the context information describing the nominal specifications of the battery, and other context information useful in determining qualitative results. This can be done in several ways. The operator may be prompted to enter key values, such as the nominal battery power, that are normally printed on the battery; the operator can enter the battery part number and the smart device can download the key data from the manufacturer's website; or the operator can use the smart device 14 for detecting battery identification information from the battery, for example, by scanning the bar code label on the battery, thus obtaining the battery part number and thereafter downloading the required context information. When the tester of the invention is used to periodically test a number of identical batteries, for example a vehicle fleet or a stationary battery bank (hereinafter more specifically explained), the context information may be permanently stored in the smart device, which eliminates the repeated entry step.

In step 96 The smart device selects a suitable algorithm for analyzing the raw data using the context information. For example, it is known that batteries that are partially discharged may still be evaluated, but that different types of batteries require different "compensation curves." See, for example, U.S. Patent 5,821,756 to McShane et al. By inputting the battery context information, such as a part number or alternatively the battery type, the battery power and the like, the smart device may select the correct algorithm for analyzing the raw data.

In step 98 the context information and the measured data are used to calculate a qualitative battery condition; for example, it is determined whether the battery is well preserved and discharged, fully charged but not in good condition, and the like. In step 100 it is determined that the battery passes or does not pass this test, and in step 102 is a recommendation (for example, "battery ok" or "replace battery") given. This information will then be in step 104 displayed on the screen of the smart device.

In step 106 can the smart device 104 used to collect additional information relating to the battery; For example, when installed in a vehicle, the vehicle identification number (VIN) may be detected by scanning the tag, which is present in all modern vehicles. Alternatively, the information on the license plate of the vehicle or the number identifying the vehicle in a fleet may be detected. This vehicle identification information is then stored together with the qualitative battery status information.

Finally, in step 108 the stored information is exported, for example to a central computer of a service center or the like.

The method of using a graphical bitmap to display battery characteristics, as previously described, may also be applied to simplified battery test circuits designed for semi-permanent attachment to batteries. In this embodiment, the simplified battery tester functions 12 as a continuous battery power monitor, and the graphic image is periodically updated to indicate the most recent measurements. By scanning the device 12 at any time by means of a remote smart device 14 The current measurements of the battery can be captured and analyzed, and qualitative status results can be calculated and displayed.

In the foregoing part of the application, an embodiment of the invention has been described in which the smart device inter alia performs the analysis of the raw data received from the simplified tester; d. that is, the smart device has the algorithms needed to process raw data and battery identification information to evaluate a battery. However, it has already been briefly referred to further embodiments, in which the smart device is used in different ways, wherein the processing of the raw data is handled differently. These embodiments will be described in more detail below. Additional enhancements are also discussed.

In a first further embodiment, referred to as the "web client" embodiment, the smart device is again provided with an application program or "app" that has software that allows the smart device Device can effectively control the collection of raw data from the simplified tester, in which, however, the raw data passed from the smart device, which functions as a "Web client", to a remote computer functioning as a "Web server" which analyzes the raw data and passes the result of the check to the smart device, and performs other functions such as storing the data for long-term prediction and the like. Thus, in this embodiment, the smart device is again provided with software that prompts the user to scan the screen of the simplified tester so that raw data is obtained to scan the bar code or UPC on the battery to obtain the battery identification data, to scan the vehicle identification number (VIN) and the like. This data and this information is then transmitted to the web server for analysis and further processing.

In a second further embodiment, referred to as the "web browser" embodiment, the smart device need not have a dedicated app. Instead, the smart device only functions as a web browser, ie, upon activation, for example, by scanning a QR code on the simplified test device containing the web server's Internet address, the smart device simply picks up the web server, which in turn responds to the user with a series of prompts. The smart device then displays it for the user performing the required actions, and the smart device transmits the results to the web server, which in turn performs the analysis.

It will be apparent to those skilled in the art that a smart device per se is not needed for this "web browser" embodiment of the invention, as any device capable of capturing the raw data and battery identification information from the simplified battery tester will. and supports a web browser function that can perform required functions.

Both further embodiments have the significant advantage that the smart device need not be able to perform the analysis, but essentially serve to transmit raw data and battery identification information to the web server, which means that the smart device need not be equipped with the specific information needed to properly analyze each of the many hundreds of different battery models that are on the market. Instead, this information may simply be stored in a database maintained in conjunction with the web server, which is simpler than repeatedly updating a database for download to various smart devices as new battery models become available. The second "web browser" embodiment provides the further advantage that no different types of apps need to be provided to support the various types of smart devices that are currently available.

In a further possible improvement, the battery may be provided with a device that passes the battery identification data directly to the simplified battery tester, which may then transmit the data via the QR code along with the raw data to the smart device. This would greatly simplify the process of providing reliable battery identification data to the smart device for analysis as above, as well as providing the data from the smart device to the web server for analysis as in the embodiments described below. This could be accomplished by incorporating an "RFID chip" into the battery during manufacture, which is used, for example, to identify pets and other animals. The RFID chip would be encoded to transmit an identification of the battery to a corresponding RFID receiver provided in the simplified battery tester.

Thus, according to this aspect of the invention, a web-based battery diagnostic system is provided. In a first "web client" embodiment, a smart device running a specially developed app is used to capture raw test data from a simplified tester. The app may be configured to acquire battery identification data by scanning a battery UPC code or more detailed information including a unique ID or a bar code, by RFID or by user input, and may further use application identification information such as VIN code in vehicle context or other application identification information how to capture an identification of a location.

The raw check data and the battery identification information and the application identification information are then transmitted from the smart device to a remote computer operating as a web server and having analysis protocols and algorithms for calculating results and diagnoses based on the provided data. The web server returns these results for presentation to the smart device to the user.

In a second "web browser" embodiment, the user accesses a remote web server using the smart device as a web browser, or uses a separate device that can serve as a web browser, such as a personal computer , The web server is provided with analysis protocols and algorithms for calculating results and diagnoses based on provided data. The smart device receives raw test data from the simplified tester, as well as battery identification information, and provides it, optionally together with "application identification information", directly to the web server. Such application identification information may describe the specific application in which the battery is used, for example, starting automobiles, as a backup in the industry, as a backup in telecommunications, in an electric or hybrid vehicle, or in a Marine Deep Cycle. Such information may be used to customize the context information being collected and the algorithms used to determine the battery condition. The web server applies stored analysis logs and algorithms and calculates results and diagnostics based on the data provided. The results are displayed to the user in the browser.

In the first "web client" embodiment, the software on the smart device can be very simple and does not need to be updated frequently because the battery analysis algorithm is on the web server; in the second "web browser" embodiment, dedicated software / applications on the smart device may be completely eliminated. In both embodiments, a major benefit is that the analysis software and the battery information database are located in a central location and can be updated and managed with minimal complexity. Further, especially in the "web browser" embodiment, the need to develop and maintain software applications for different mobile operating systems such as iOS, Android, Symbian, Windows 8, etc. is eliminated.

In accordance with another aspect of the invention, a battery tester is provided that is capable of providing useful test results without requiring a user to enter data. In this case, a simplified battery tester is connected to a battery, and after a specific time delay, an automatic test routine for measuring battery parameters begins. The user does not have to enter anything into the simplified tester. The simplified tester automatically acquires data and displays the data in machine-readable form, such as a QR code, and optionally in a user-readable form.

As previously mentioned, in previously used battery testers, the user had to read battery context information such as test parameters from the battery label and enter that data into the tester. However, this process was buggy because the user may not be reading, misreading, or making errors when entering the data validator. According to an important aspect of the invention, the smart device is designed to digitally acquire the battery identification information. This battery identification information could be in the form of a UPC code or other optically readable code, or it may be supplied by an RFID chip that is built into the battery during manufacture.

If the battery identification information is to be provided by means of an RFID chip, then the simplified battery testing device, which in this embodiment will include an RFID receiver, will be configured to automatically acquire the RFID information of the battery immediately after the tester has connected the battery. The simplified test apparatus will display on its display the battery identification information acquired by the RFID transmission together with the raw data, for example by means of a QR code.

The smart device will acquire the battery identification information based on the optical code on the battery label or on the RFID tag after it has been identified by the simplified tester, again together with the raw battery test data. In addition, the smart device may detect vehicle or application identification information, for example, by means of a VIN scan. The battery and vehicle identification information is used by the smart device to look up the appropriate context values and specific test variables so that complete and comprehensive battery testing and diagnostics can be performed. The database of battery context information and test parameters may be stored in the smart device or residing on a web server that is dynamically accessed to perform a look-up of the battery analysis parameters in a database and to communicate the critical parameters to the smart device.

Together, these features allow a comprehensive battery test with specific battery test parameters without the user having to enter data. This eliminates human error and fraud and increases testing speed.

These embodiments of the invention will now be discussed in detail with reference to the accompanying drawings.

As previously explained, shows 6 a schematic of the components used for the new "Web Client" embodiment and the new "Web Browser" embodiment of the invention. 7 FIG. 12 shows a flow chart of the steps of the "web client" embodiment, and FIG 8th Fig. 10 shows a flow chart of the steps of the "web browser" embodiment. 9 shows a flowchart of a modification of the process of 8th ,

6 shows a simplified battery tester 120 that with a battery 122 through wires 126 connected is. The tester 120 As previously described, performs appropriate tests to generate raw data that can be analyzed to determine the condition of the battery and generates a QR code as shown 124 , This is then passed through a smart device 128 read. The smart device 128 will then typically prompt the user for the VIN or other machine-readable code indicative of the vehicle or other contextual information 130 is designated, and the battery identification information via a bar code, a UPC or other machine-readable code, which with 132 is designated to scan.

Optionally, the battery identification information may be from an RFID chip 134 provided in the manufacture of the battery. This could be used to provide unambiguous identification of each battery, which could be very valuable. As is known, such an RFID chip transmits 134 a unique identification code when addressed by a nearby RFID receiver. This response may be performed and the battery identification information provided by an RFID receiver 136 , the part of the simplified battery tester 120 is, is detected and added to the raw data can be considered part of the QR code 134 to the smart device 128 be transmitted.

The raw data and battery identification information is then provided by the smart device 128 as in 140 shown over the internet to a web server 138 transfer. In this step, the smart device works 128 as a web client. That is, the software app running on the smart device 128 running, assigns the Internet address of a web server 138 so that the raw data and the battery identification information are transmitted thereto. The web server then pulls one or more databases 142 . 144 To determine the correct battery characteristics, perform the analysis and send the result back to the smart device 128 for a suitable action.

7 shows a flow chart of these steps for the first "Web client" embodiment, in which the smart device 128 has an app that causes the smart device as needed instructions for the user, the battery tester 120 for scanning the QR code, scanning the battery bar code, scanning the VIN number, etc. Thus, the user starts in a first step 150 the application. In an optional step 152 the user is prompted to scan or enter the VIN with the smart device. In a second optional step 154 the user is prompted to scan the battery identification code (which could be the UPC or a separately provided bar code or the like) with the smart device. If the battery has an RFID chip, the simplified battery tester 120 determine battery identification based on it so that the user does not need to make any input to ensure that this data is captured correctly. Other data, such as the location of the exam, can be found in step 156 be entered.

The battery tester 120 is already connected to the battery or is in step 158 connected to the same. The tester 120 then leads in step 160 the automatic test routine and shows in step 162 the raw data (and the RFID battery identification data if the battery and the battery tester are equipped accordingly). The user will then step in 164 to scan the QR code to get the raw data. The smart device, which serves as a web client, then sets in step 166 connect to a remote computer 138 which serves as a web server and transmits in step 168 the raw data together with the battery identification information, the VIN and other collected data to the server 138 , The server then accesses step 170 to the database to obtain the appropriate battery information, such as its power, the standard to which the power relates, and one or more coefficients needed to convert measured raw data to standardized battery power units, such as CCA, CA, ampere hours, etc. to determine. These coefficients include the aforementioned values, which differ significantly in batteries of different design classes and in batteries within these classes, especially within the AGM class. The server then performs in step 172 the algorithm for determining the battery state and transmits in step 174 the result to the smart device. The smart device then shows in step 176 the result for a user for an appropriate action.

As previously explained, it is particularly difficult to test batteries that are located in remote or inaccessible spaces in the vehicle. Often, batteries are located below a seat or in a remote location that is not easily accessible. In this case, remote battery terminals are provided at a location that is readily accessible for a foreign start or battery diagnostic procedure to be performed. Ohmic tests of a battery made at the remote terminals, however, are corrupted due to the resistance created by the connections between the battery and the remote terminals used for testing. If the resistance of the particular design is known, then an adjustment of the test results can be made to obtain an accurate diagnosis. Database 142 . 144 ( 6 ) may have such adjustment factors for each vehicle, and when the VIN is scanned, the smart device or the web server may in step 170 Look up and apply the appropriate adjustment factor so that a highly accurate test result is obtained.

8th shows a second "web browser" embodiment in which the smart device is used merely as a web browser or in which the smart device per se is replaced by another Device is replaced, having the necessary data input and communication capabilities, such as a personal computer. A reference hereinafter to a smart device is to be understood as including the latter possibility.

In step 200 the user starts the web browser function on the smart device and uses it in step 202 to access a specific web server. In step 204 When the web server starts a web application program that includes the battery check and analysis routine, it begins a web browser review session by sending a dynamic web form and appropriate instructions to the web browser in step 206 , The user then sees the form on the screen of the browser and completes it in step 208 typically by acquiring the QR code from the simplified tester (which as previously described with respect to FIGS 7 described in step 158 connected to the battery in step 160 has executed the test routine and in step 162 has displayed the raw data), detecting a bar code, a UPC or an RFID code identifying the battery, detecting the VIN code, if so provided, or manually entering the above-mentioned or other required information into the web form. The smart device then carries the completed form in step 210 back to the web server.

The web application then parses in step 212 the returned data and sends in step if needed 214 another request. After all the needed information has been collected, the web application analyzes the returned data, closing in step 216 start the diagnosis and send in step 218 the test report to the browser. This one will be in step 220 received, and the user can take an appropriate action.

For an alternative, the in 9 shown is the simplified battery tester 120 equipped with the web address of the web server. A test would then involve connecting the simplified battery tester 120 with the battery 122 in step 240 kick off; the simplified battery tester 120 would then step in 242 perform the test and in step 244 display a QR code (or equivalent) with the raw data and Internet address of the server and the battery identification information if the battery is equipped with an RFID chip. In step 250 Then the user would simply use the QR code with the smart device 128 Scan, which automatically uses the address contained in the code in step 252 to open a browser session with the web server. The smart device 128 would then use the Internet address to communicate with the web server, and the process would be essentially as previously described in connection with 8th completed, the steps being similarly designated. The step 254 is different from step 208 in 8th to the effect that the data image already in step 250 has been recorded.

The above-described method of using a smart device as a web browser and sending battery check data to the web server can also be used with devices primarily used for other diagnostic purposes, i. H. unlike smartphones, tablet computers and the like. For example, various "workshop diagnostic platforms" can be used, essentially tablet computers with specific testing software and suitable connection components and cables used in garages in the diagnosis and repair of vehicles.

Some of these workshop diagnostic devices differ from smart devices per se in having no components and software for optically capturing data, i. that is, they are unable to read a QR code from a simplified test device, for example. In such cases, the simplified test apparatus is connected to the workshop diagnostic platform by the already existing wiring of the vehicle in the manner described below. The shop diagnostic platform may then be used to perform battery diagnostics or to run either the web client embodiment or the web browser embodiment of the present invention. In this configuration, various information, such as the VIN or other data, will be available based on previously performed testing procedures for the workshop diagnostic platform, for example, due to performing an on-board diagnostic scan and extracting information from the vehicle computer. In this case, a portion of the information needed to perform the battery check algorithm may be shared between the vehicle diagnostic application and the battery check procedures, allowing for testing with less user interaction.

The arrangement of components needed to use the workshop diagnostic platform for the alternative described above is schematically illustrated in FIG 10 shown. The simplified battery tester 306 is with a battery 302 connected in a vehicle 300 is installed. The battery tester 306 is via a wire connection 304 , which is typical of electric battery testers, for example, a pair of Kelvin connections, with the battery 302 connected. At the in 10 shown embodiment, the Battery Tester 306 one or more methods for outputting battery test data and other data obtained from the simplified battery tester 306 receive, implement. So that it can also be used for other applications (as described above), the tester can 306 an optical output device such as a screen for displaying a QR code 308 , a radio communication connection 312 for Bluetooth, Wi-Fi or other radio methods or a DC power communication device 310 exhibit. The DC power communication device 310 uses a hard-wired connection 304 for sending battery test data and other data via the DC cabling 314 of the vehicle 300 , That way, a receiver can 318 Connected to the DC wiring of the vehicle receiving battery check data. At the in 10 As shown, this receiver could have an OBD interface 318 a workshop diagnostic platform 324 be. The OBD interface 318 gets to the OBD port 316 with the vehicle DC cabling 314 connected. Thus, the workshop diagnostic platform could 324 the battery test data via a wire connection 320 , an optical image sensor or the like via the OBD port 316 receive.

Although in this embodiment the OBD port 316 is used to access the vehicle DC cabling, the transmission of information does not include the vehicle computer or the OBD system. Rather, the OBD port is pointing 316 a pin connected to the positive terminal of the battery via the vehicle wiring, and another pin connected to the vehicle ground connected to the negative terminal of the battery. A digital message containing the test results and associated data is simply transmitted and effectively superimposed on the (nominal) 12 volts across the battery terminals. In this way, the DC communication of the test data can be performed without involving the vehicle computer system. Even if a use of the vehicle OBD ports 316 for use with the vehicle DC cabling, could be a DC communication receiver 318 at another location of the vehicle DC cabling 314 get connected.

Alternatively, the workshop diagnostic platform 324 if appropriate, the battery test data using an image sensor and capturing an image on the display screen 308 of the simplified battery tester 306 as described above, or could the battery check data be via a radio receiver 322 through direct communication with the radio transmitter 312 receive.

The workshop diagnostic platform 324 can then essentially assume the function of the previously described smart device, ie have a user interface and directly execute a battery diagnostic software. Alternatively, the workshop diagnostic platform 324 to be able to 326 to establish an Internet connection, and may as described previously battery test data and other vehicle data provided by the OBD interface 318 be received, to a remote server 328 according to either the web client embodiment or the web server embodiment of the present invention.

In this embodiment, the simplified battery tester may provide battery test data for a diagnostic tool that is already being used in the workshop, thereby reducing the number of tools a technician must use. Using the Internet for communication with a web server having the analysis software, the diagnostic tool can also be simplified.

11 shows the steps taken by the workshop diagnostic platform 324 (in 11 as a "diagnostic tool") to perform the method of the present invention. As previously mentioned, the simplified battery tester 306 in step 350 connected to the battery, performs in step 352 The check routine will generate the raw data and optionally a web server address and provide this information in step 356 out. The workshop diagnostics platform connected to the OBD port of the vehicle 324 leads in step 358 Check through and then receive in step 360 the battery test data and accesses in step 362 via the OBD port to the available context information such as the VIN from the vehicle computer. The workshop diagnostic platform 324 then performs the steps necessary to analyze the data for characterizing the battery in step 364 out.

This can be done in one of the three ways previously described. The workshop diagnostic platform 324 can in step 368 carry out the analysis yourself; this corresponds to the first embodiment in which the smart device does not contact a web server. Alternatively, the workshop diagnostic platform 324 in step 366 Follow the "web client" approach, where the workshop diagnostic platform 324 Software that prompts the user, the various input steps as in 7 perform; or she can step in 370 the "web browser" approach of 8th and 9 In essence, the web server essentially controls the collection of data as needed. In both the "web client" approach and the "web browser" approach, the web server performs the previously described battery analysis. In any case will step in to the user 372 communicated the results of the test.

Thus, a device sold as a workshop diagnostic platform or the like that differs from a smartphone or a tablet computer not intended for use in a workshop may nevertheless be considered a "smart device" within the meaning of the following claims understood as having the necessary functions.

Although the invention has been described in the context of testing a vehicle battery, it may be used in other battery testing applications. For example, it is common practice to use large rows of "stationary" batteries, such as to provide backup power for backup power from traffic lights, hospitals, telecommunications equipment, and other critical equipment. Such rows of batteries are normally kept fully charged, so the question of whether or not batteries are possibly discharged normally does not occur. However, such batteries lose storage capacity over time, and accordingly, it is important to monitor their deterioration. This is normally achieved by the ohmic measurements given above.

According to the invention, the complex and expensive battery testers that are currently in use, which typically include a test circuit for making such ohmic measurements in conjunction with a user interface for allowing the user to enter a battery identification number or the like, may have a memory for storing the results for each Battery, communication means for transmitting reports to a central computer, which monitors the results, and the like, are replaced by the simplified battery tester and the smart device according to the invention.

In such a use, the simplified battery tester would 12 in turn connected to each battery to be tested and perform the above-described basic ohmic measurement, that is, measure the internal resistance of the battery. This would then become the smart device as described above 14 transferred, and the smart device 14 Also as explained above, it would also be used to analyze the raw data to evaluate the battery for a standard for batteries of this type and to record the result along with an identification of the battery. The results for a large number of batteries that have been tested could then be downloaded to a central computer, printed or the like.

Alternatively, or in addition, results of a one-day battery test may be compared to previous test results for the same battery to determine trends. The battery check results may be stored in the smart device or stored in a remote database that the smart device can dynamically access. In this way, the operator can identify a battery that has already been tested using any battery identification discussed above. After an identification of the battery, the current test results are automatically compared with the previous test results to provide information regarding a rate of deterioration of the battery.

Finally, as previously mentioned, the tester of the invention is not limited to testing a battery, but may be used in testing many different types of devices, devices or components. In any event, as previously mentioned, the simplified test apparatus would be provided with suitable components for connecting the microprocessor control unit (MCU) of a tester to the circuitry of the apparatus, apparatus or component to be tested, and the MCU would be with appropriate software For example, to perform a physical measurement of a value (as in the embodiment for testing a battery), to interrogate an internal memory (as in the OBD example), the identification of the item under test (as in the above-described use of an RFID chip ) or the like. The simplified tester would then transmit this information to an associated smart device for analysis and taking an appropriate action.

In addition to the use of test equipment according to the invention in testing a battery or in downloading OBD data, there are numerous applications for test equipment according to the invention, both in the automotive industry and outside it. For example, telecommunications equipment is usually tested using test equipment that measures parameters such as a data rate to verify that the subscriber is getting the promised service. Such testers are currently usually integrated as previously described; that is, they include both a circuit for applying a test signal to the device and measuring a response thereof, and a microprocessor with suitable software for analyzing the results, receiving an operator input via a user interface and reporting the results. As previously discussed, in accordance with the invention, an integrated tester may be replaced with a simplified tester for performing the basic test operation and for passing the raw data resulting therefrom into a suitably programmed smart device for analysis, user input, passing results, and the like.

Accordingly, the basic operation of the simplified tester of the invention may be generally stored as obtaining data indicating the state of the device, device or component to be tested, including measuring a value (as in the case of a battery) Data (e.g., downloading data indicating the state of a vehicle from the OBD port thereof) or injecting a signal into a circuit and measuring its response (e.g., testing a telecommunications device) and transmitting the data thus obtained to the smart device; Device are described. As previously discussed, the smart device provided with the appropriate software (typically by downloading a software app offered by the manufacturer of the particular test device) then determines the state of the device, device, or component based on the data received. As previously described, the data analysis function may alternatively be performed by a web server in response to data passed by the smart device.

Therefore, while several preferred embodiments of the invention have been described in detail, numerous improvements and enhancements are within the knowledge of those skilled in the art, and thus fall within the scope of the invention, unless they are excluded by the following claims.

It is explicitly pointed out that all features disclosed in the description and / or the claims are considered separate and independent of each other for the purpose of original disclosure as well as for the purpose of limiting the claimed invention independently of the feature combinations in the embodiments and / or the claims should. It is explicitly stated that all range indications or indications of groups of units disclose every possible intermediate value or subgroup of units for the purpose of the original disclosure as well as for the purpose of restricting the claimed invention, in particular also as the limit of a range indication.
