Description

Für die auf dem Markt vorhandenen verschiedenen Batterie- und Akkusysteme benötigt man unterschiedliche Lade- bzw. Entladeverfahren, um die unterschiedlichen Ladeparameter wie Strom, Spannung, Kapazität etc. berücksichtigen zu können. Batterien und Akkus auf der einen Seite und das Lade- bzw. Entladegerät auf der anderen Seite müssen deshalb aufeinander abgestimmt sein.For those on Different battery and accumulator systems available on the market require different ones Loading and unloading procedures to the different loading parameters like current, voltage, capacity etc. take into account to be able to. batteries and batteries on one side and the charger or discharger on the one other side must therefore be coordinated.

Es ist bereits ein Verfahren zum Laden und gleichzeitigen Prüfen des Zustandes eines Nickelcadmium-Akkumulators bekannt, bei dem die Ladezyklus-Messphasen mit Entladeintervallen vergleichsweise kurzer Dauer eingeschoben sind. Während der Messphasen wird der Innenwiderstand des Akkumulators unter unterschiedlichen Lade- und Entladezuständen gemessen ( DE 38 11 371 A1 ). Mit diesem Verfahren kann jedoch der Typ des Akkumulators nicht erkannt, sondern nur der Lade- und Entladestrom eingestellt werden.A method for charging and simultaneously checking the condition of a nickel-cadmium accumulator is already known, in which the charging cycle measurement phases with discharge intervals are inserted for a comparatively short duration. During the measurement phases, the internal resistance of the battery is measured under different charge and discharge conditions ( DE 38 11 371 A1 ). With this method, however, the type of the accumulator cannot be recognized, only the charging and discharging current can be set.

Weiterhin ist ein Verfahren zum Laden von Akkumulatoren, insbesondere solchen für Modellbaufahrzeuge bekannt, bei welchem mittels eines Ladegeräts ein Ladestrom und/oder eine Ladespannung eingestellt und die Akkumulatoren hiermit versorgt werden ( DE 39 24 499 A1 ). Hierbei wird mit Hilfe des Ladegeräts oder zugehörigen Einrichtungen Art und der Innenwiderstand eines Akkumulators bzw. einer Reihe parallel und/oder hintereinander geschalteter Akkumulatoren automatisch festgestellt. Unter Verwendung eines Mikroprozessors werden in Abhängigkeit von der festgestellten Art und in Abhängigkeit von dem festgestellten Innenwiderstand Ladestrom und/oder -spannung und/oder -dauer automatisch festgelegt und am Ausgang des Ladegeräts automatisch eingestellt. Auch hierbei kann die Art der Akkumulatoren, d. h. der Akku-Typ, nicht erkannt werden.Furthermore, a method for charging batteries, in particular those for model construction vehicles, is known in which a charging current and / or a charging voltage is set by means of a charger and the batteries are supplied with them ( DE 39 24 499 A1 ). The type and the internal resistance of an accumulator or a series of accumulators connected in parallel and / or in series are automatically determined with the aid of the charger or associated devices. Using a microprocessor, the charging current and / or voltage and / or duration are automatically determined as a function of the type determined and as a function of the internal resistance determined and are automatically set at the output of the charger. The type of the accumulators, ie the type of accumulator, cannot be recognized here either.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Einrichtung zu schaffen, mit der verschiedene Typen von Akkumulatoren oder Batterien ohne Fehlbedienung richtig auf- oder entladen werden können.The The invention is therefore based on the object of establishing a device create with which different types of accumulators or batteries without Incorrect operation up or down can be discharged.

Diese Aufgabe wird gemäß den Merkmalen des Schutzanspruchs 1 gelöst.This Task is performed according to the characteristics of the Protection claim 1 solved.

Der mit der Erfindung erzielte Vorteil besteht insbesondere darin, dass alle erforderlichen Daten über den Akkutyp, die Zellenzahl, die Kapazität und andere Lade- und Entladeparameter in einem Speicherbaustein enthalten und der Batterie bzw. dem Akku zugeordnet sind und von dort in ein Ladegerät übertragen werden können. Der Speicherbaustein ist vorzugsweise lösch- und erneut beschreibbar, sodass er für verschiedene Akkutypen verwendet werden kann.The Advantage achieved with the invention is in particular that all necessary data about battery type, number of cells, capacity and other charging and discharging parameters contained in a memory chip and the battery are assigned and can be transferred from there to a charger. The memory chip is preferably deleted and rewritable so that it can be used for different battery types can be.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben.On embodiment The invention is illustrated in the drawing and is described below described in more detail.

Die einzige Figur zeigt ein Ladegerät 1 und ein Akkupack 2, der hier aus mehreren in Reihe geschalteten Akkumulatoren 3 bis 10 besteht, die in eine Folie 17 eingeschweißt sind. Von dem Ladegerät 1 führen zwei Anschlussleitungen 11, 12 von unterschiedlicher Polarität zum Akkupack 2, mit deren Hilfe die Akkumulatoren 3 bis 10 als Akkupack aufgeladen werden. Der Akkupack 2 stellt hierbei für das Ladegerät eine Einheit dar. Handelt es sich bei den Akkumulatoren 3 bis 10 um NC/NiMH- oder Blei-Akkus, so sind diese in der Regel in Reihe geschaltet. Bei Lithium-Akkus ist meistens eine kombinierte Reihen-Parallel-Schaltung vorgesehen.The only figure shows a charger 1 and a battery pack 2 , which here consists of several accumulators connected in series 3 to 10 which consists in a slide 17 are welded in. From the charger 1 run two connection lines 11 . 12 of different polarity to the battery pack 2 , with the help of which the accumulators 3 to 10 can be charged as a battery pack. The battery pack 2 represents a unit for the charger. It concerns the accumulators 3 to 10 NC / NiMH or lead batteries, these are usually connected in series. A combined series-parallel connection is usually provided for lithium batteries.

Der Akkupack 2 ist mit einem Speicherbaustein 13 versehen, in dem alle relevanten Daten des Akkupacks 2 gespeichert sind. Dieser Speicherbaustein 13 ist über eine Leitung 14 mit dem Ladegerät 1 verbunden, in dem sich ein Lesegerät befindet, mit dem die Daten des Speicherbausteins 13 gelesen werden können. Entsprechend der gelesenen Daten, die sich beispielsweise auf die Gesamtspannung bzw. die Gesamtkapazität des Akkupacks 2 beziehen, werden die Ausgangsspannung bzw. der Ausgangsstrom des Ladegeräts geregelt. Der Speicherbaustein 13, der ein EEPROM oder ein Mikroprozessor mit Speicher sein kann, ist mit dem Akkupack 2 verbunden, beispielsweise aufgeklebt oder eingeschweißt.The battery pack 2 is with a memory chip 13 provided in which all relevant data of the battery pack 2 are saved. This memory chip 13 is over a line 14 with the charger 1 connected, in which there is a reader with which the data of the memory chip 13 can be read. Corresponding to the data read, which relates, for example, to the total voltage or the total capacity of the battery pack 2 relate, the output voltage or the output current of the charger are regulated. The memory chip 13 which can be an EEPROM or a microprocessor with memory is with the battery pack 2 connected, for example glued or welded.

In diesem Speicherbaustein 13 sind alle erforderlichen Daten über Akkutyp, Zellenzahl, Kapazität und andere Lade- bzw. Entladeparameter gespeichert. Der Speicherbaustein 13 muss nicht auf einen Batterie- oder Akkutyp zugeschnitten sein. Es ist vielmehr auch möglich, ihn mehrfach zu beschreiben und wieder zu löschen.In this memory block 13 all necessary data about the battery type, cell number, capacity and other charging and discharging parameters are saved. The memory chip 13 need not be tailored to a battery or accumulator type. Rather, it is also possible to describe it several times and delete it again.

Ist ein Akkupack oder ein Akku defekt, kann der Speicherbaustein 13 für einen anderen Akkupack bzw. einen anderen Akku eingesetzt werden.If a battery pack or a battery is defective, the memory module can 13 for a different battery pack or a different battery.

In dem Speicherbaustein 13 können zusätzlich Sensoren vorgesehen sein, beispielsweise Temperatursensoren, welche weitere Informationen liefern, die Einfluss auf das Ladeverhalten nehmen können. Mit solchen Sensoren kann beispielsweise eine Notabschaltung bei Überhitzung eines Akkupacks vorgenommen werden.In the memory block 13 In addition, sensors can be provided, for example temperature sensors, which provide further information that can influence the charging behavior. With such sensors, for example, an emergency shutdown can be carried out when a battery pack overheats.

Außer dem Daten-Lesegerät in Ladegerät 1 handelt es sich bei dem Ladegerät 1 um ein übliches Universalladegerät.Except the data reader in charger 1 is the charger 1 a common universal charger.

Es versteht sich, dass die Übertragung der Daten vom Speicherbaustein 13 zum Ladegerät 1 auch mittels Funk, Infrarot, Ultraschall etc. erfolgen kann.It is understood that the transfer of data from the memory chip 13 to the charger 1 can also be done by radio, infrared, ultrasound, etc.
