Abstract

Die Erfindung betrifft im Wesentlichen eine Kombination existierender bzw. in der Einführung befindlicher Technologien zur Energieübertragung und Speicherung für sogenannte e-Cars mit einer neuen Energieaustausch-Infrastruktur an Straßenkreuzungen mit der eine Verbesserung der Fahrzeugreichweite durch häufigere hochenergetische Nachladung erreicht wird. Bei entsprechender Dichte derartiger Einrichtungen an Kreuzungen können zumindest kleinere sekundäre langsam ladende Energiespeicher in den Fahrzeugen eingesetzt werden. Darüber hinaus kann die Steuerungsinfrastruktur solcher Kreuzungen auch leicht zusätzlich zur Verkehrsdichteerkennung und Verkehrs-Beeinflussung herangezogen werden.The invention relates essentially to a combination of existing or in the introduction of technologies for energy transmission and storage for so-called e-cars with a new energy exchange infrastructure at road junctions with which an improvement in the vehicle range is achieved through more frequent high-energy recharging. With a corresponding density of such devices at intersections, at least smaller secondary slow-charging energy stores can be used in the vehicles. In addition, the control infrastructure of such intersections can easily be used in addition to traffic density detection and traffic influencing.

Description

Die Erfindung betrifft ein System zur induktiven Ladung von elektrisch betriebenen Fahrzeugen.The invention relates to a system for the inductive charging of electrically operated vehicles.

Die Reichweite elektrischer Fahrzeuge (e-Cars) ist bislang maßgeblich durch die eingeschränkte Kapazität, das hohe Gewicht und langsame Wiederaufladung von elektrischen Energiespeichern beschränkt. Um die Reichweite und die maximale Nutzungsdauer des e-Cars im Rahmen der typischen Anforderungen des Individualverkehrs zu halten, ist eine große Speicherkapazität mitzuführen, die das Gewicht erhöht, die Zuladung begrenzt und zudem eine hohe Ladezeit zur Folge hat.The range of electric vehicles (e-cars) has been largely limited by the limited capacity, the high weight and slow recharge of electrical energy storage. In order to keep the range and the maximum useful life of the e-car within the typical requirements of the individual traffic, a large storage capacity must be carried along, which increases the weight, limits the payload and also has a high charging time.

Es sind bisher bspw. Konzepte zum schnellen Austausch vollständiger Akkumulatorsätze bekannt.So far, for example, concepts for the rapid replacement of complete accumulator sets are known.

Darüber hinaus existieren feste Ladestationen für e-Cars, entweder in privaten Einrichtungen oder an öffentlichen Plätzen mit unterschiedlichen Abrechungsverfahren. Ein Anschluss an diese Stationen erfolgt in der Regel über ein Elektro-Kabel – es ist aber, im Falle einer Wechselstromversorgung, auch eine induktive Kopplung mit anschließender Gleichrichtung im Fahrzeug denkbar.In addition, there are fixed charging stations for e-cars, either in private facilities or in public places with different billing procedures. A connection to these stations is usually via an electric cable - but it is, in the case of an AC power supply, also an inductive coupling with subsequent rectification in the vehicle conceivable.

Die der Erfindung zu Grunde liegende Aufgabe besteht nun darin, ein System zur kurzfristigen Ladung von elektrisch betriebenen Fahrzeugen anzugeben, bei dem die Reichweite dieser Fahrzeuge mit möglichst geringem Gesamtaufwand erhöht wird.The object underlying the invention is now to provide a system for short-term charging of electrically operated vehicles, in which the range of these vehicles is increased with the least possible total effort.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 erfindungsgemäß gelöst. Die weiteren Ansprüche betreffen bevorzugte Ausgestaltungen der Erfindung.This object is achieved by the features of claim 1 according to the invention. The further claims relate to preferred embodiments of the invention.

Die Erfindung betrifft im Wesentlichen eine Kombination existierender bzw. in der Einführung befindlicher Technologien zur Energieübertragung und Speicherung für sogenannte e-Cars mit einer neuen Infrastruktur zum Energieaustausch an Straßenkreuzungen mit der eine Verbesserung der Fahrzeugreichweite durch häufigere hochenergetische Nachladung erreicht wird. Bei entsprechender Dichte derartiger Einrichtungen an Kreuzungen können zudem kleinere sekundäre langsam ladende Energiespeicher in den Fahrzeugen eingesetzt werden. Darüber hinaus kann die Steuerungsinfrastruktur solcher Kreuzungen auch leicht zusätzlich zur Verkehrsdichteerkennung und Verkehrsbeeinflussung herangezogen werden.The invention relates in essence to a combination of existing or in the introduction of technologies for energy transmission and storage for so-called e-cars with a new infrastructure for energy exchange at road intersections with the improvement of the vehicle range is achieved by more frequent high-energy recharge. With appropriate density of such facilities at intersections also smaller secondary slow-charging energy storage can be used in the vehicles. In addition, the control infrastructure of such intersections can also be easily used in addition to traffic density detection and traffic control.

Nachfolgend wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert.The invention will be explained in more detail with reference to embodiments shown in the drawing.

Dabei zeigen:Showing:

1 eine Übersichtsdarstellung zur Erläuterung einer erfindungsgemäßen kurzfristigen Ladung von elektrischen Fahrzeugen im Bereich einer Straßenkreuzung und 1 an overview to explain a short-term charge according to the invention of electric vehicles in the area of a road intersection and

2 eine Prinzipdarstellung zur Erläuterung des Aufbaus und der Funktionsweise eines entsprechenden Systems. 2 a schematic diagram for explaining the structure and operation of a corresponding system.

1 zeigt eine Straßenkreuzung K als Energieaustauschplatz, die in den Abbrems-, Halte- und Beschleunigungsbereichen eingelassene Induktionsvorrichtungen 1 mit jeweils einer Vielzahl von Induktionszonen 3 aufweist und in deren Bereich sich beispielhaft ein elektrisch betriebenes Fahrzeug bzw. ein e-Car C mit einem schnellladefähigen elektrischen Energiespeicher 2 befindet. 1 shows a road junction K as an energy exchange place, the induction devices embedded in the deceleration, holding and acceleration areas 1 each with a variety of induction zones 3 has and in the range, for example, an electrically powered vehicle or an e-car C with a fast-charging electrical energy storage 2 located.

Eine solche Straßenkreuzung K als Energieaustauschplatz bietet e-Cars C elektrische Energie an, um ihre schnellladefähigen Speicher aufzufüllen und/oder diese beim Beschleunigen im kreuzungsnahen Bereich zu unterstützen.Such a road intersection K as an energy exchange station offers e-cars C electrical energy to replenish their fast-charging memory and / or to support them in accelerating in the cross-over area.

Durch die schnellladefähigen Speicher in den e-cars wird vorteilhafter Weise vermieden, dass letztere auf Energie aus langsam ladenden elektrischen Speichern, z. B. elektrochemischen Akkumulatoren, zurückgreifen müssen. Diese nur in länger dauernden Haltephasen erneuerbare Energie aus den Akkumulatoren steht dadurch noch mehr allein für Fahrabschnitte ohne Zwischenlademöglichkeiten zur Verfügung, wodurch die Gesamtreichweite des e-cars vergrößert wird.Due to the fast-charging memory in the e-cars is advantageously avoided that the latter on energy from slow-charging electrical storage, eg. As electrochemical batteries must resort. This only in longer lasting holding phases renewable energy from the accumulators is thus even more alone for driving sections without intermediate charging options available, whereby the overall range of e-cars is increased.

Hierbei weist das elektrisch betriebene Fahrzeug C eine Ladesteuereinheit 4 auf, die von einer jeweiligen Induktionszone 3 der in den Abbrems-, Halte- und Beschleunigungsbereichen eingelassene Induktionsvorrichtungen 1 im Bereich unterhalb des Fahrzeugs C eine Lokalisationskennung 6 empfängt.In this case, the electrically operated vehicle C has a charging control unit 4 on, by a respective induction zone 3 the inductance devices embedded in the deceleration, holding and acceleration areas 1 in the area below the vehicle C a localization identifier 6 receives.

Die Ladesteuereinheit 4 des Fahrzeugs C leitet die Lokalisationskennung 6 zusammen mit eigenen Identifikationsmerkmalen des Fahrzeugs kryptographisch gesichert an einen Authentifizierungs- und Abrechnungsdienst 9 weiter, der, nach erfolgreicher Authentifizierung des Fahrzeuges, eine Kreuzungssteuerung 5 über ein Instruktionssignal 10 derart instruiert, dass der jeweilige Induktionsabschnitt 3 über eine Ansteuerleitung 11 freigegeben wird und dass über ein Anforderungssignal 12 durch den Authentifizierungs- und Abrechnungsdienst 9 die übertragene Energie erfasst bzw. berechnet wird.The charging control unit 4 of the vehicle C passes the location code 6 cryptographically secured to an authentication and accounting service together with the vehicle's own identification features 9 Next, after successful authentication of the vehicle, a crossing control 5 via an instruction signal 10 instructed so that the respective induction section 3 via a control line 11 is released and that via a request signal 12 through the authentication and billing service 9 the transmitted energy is detected or calculated.

Die Abschnitte 3 sind hierbei kleiner als Fahrzeuglängen zu wählen, um diesen eine exakte Lokalisation und der Kreuzungssteuerung 5 eine präzise Kontrolle und Messung des Energieaustausches zu ermöglichen.The sections 3 are here to choose smaller than vehicle lengths to this exact localization and crossing control 5 to allow a precise control and measurement of the energy exchange.

Das Weiterleiten der Lokalisationskennung 6 und der Identifikationsmerkmale des Fahrzeugs erfolgt dabei in einer ersten Ausführungsvariante per lokaler Funkübertragung als Teil der Kreuzungsinfrastruktur, z. B. Wireless LAN, in einer zweiten Ausführungsvariante über eine Mobilfunkverbindung 7, z. B. über UMTS, oder in einer dritten Ausführungsvariante durch Anlegen eines entsprechend modulierten magnetischen Gegenfeldes 8 an die betreffende Induktionszone 3 und somit eine direkte Rückmeldung über die Ansteuerleitung 11 zur Kreuzungssteuerung 5.The forwarding of the localization identifier 6 and the identification features of the vehicle takes place in a first embodiment by local radio transmission as part of the intersection infrastructure, z. As wireless LAN, in a second embodiment via a cellular connection 7 , z. B. via UMTS, or in a third embodiment by applying a correspondingly modulated magnetic opposing field 8th to the relevant induction zone 3 and thus a direct feedback via the control line 11 to the crossing control 5 ,

Die übertragene Lokalisationskennung 6 ist kryptographisch gesichert und variiert optional ständig über der Zeit, um einen Missbrauch zu verhindern.The transmitted localization identifier 6 is cryptographically secured and optionally varies constantly over time to prevent misuse.
