Abstract
Description
Die Erfindung betrifft ein Elektrofahrzeug mit einem Elektromotor, einem wiederaufladbaren Energiespeicher zur Stromversorgung des Elektromotors und einer Schnittstelle zum Anschließen des Energiespeichers an eine externe Stromquelle sowie ein Verfahren zum Erfassen des Energieverbrauchs eines Elektrofahrzeugs.The invention relates to an electric vehicle with an electric motor, a rechargeable energy storage for powering the electric motor and an interface for connecting the energy storage device to an external power source and a method for detecting the energy consumption of an electric vehicle.
Elektrofahrzeuge können prinzipiell sowohl über einen privaten Netzanschluss als auch über allgemein zugängliche Ladestationen, die ähnlich wie Tankstellen allen Fahrzeughaltern zur Verfügung stehen, zum Aufladen eines Energiespeichers mit Strom versorgt werden. Um den Stromverbrauch eines Elektrofahrzeugs zu erfassen und zu dokumentieren sind deshalb Rechnungen allgemein zugänglicher Ladestationen nicht ausreichend.In principle, electric vehicles can be supplied with power both via a private grid connection and via generally accessible charging stations, which, like petrol stations, are available to all vehicle owners, for charging an energy store. In order to record and document the electricity consumption of an electric vehicle, therefore, calculations of generally accessible charging stations are not sufficient.
Aufgabe der vorliegenden Erfindung ist es deshalb, einen Weg aufzuzeigen, wie der Stromverbrauch eines Elektrofahrzeugs effizient erfasst werden kann.Object of the present invention is therefore to show a way how the power consumption of an electric vehicle can be detected efficiently.
Diese Aufgabe wird durch ein Elektrofahrzeug mit den im Anspruch 1 angegebenen Merkmalen sowie durch ein Verfahren gemäß Anspruch 10 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen.This object is achieved by an electric vehicle having the features specified in claim 1 and by a method according to claim 10. Advantageous developments of the invention are the subject of dependent claims.
Ein erfindungsgemäßes Elektrofahrzeug hat eine Erfassungseinrichtung, welche die aus einer externen Stromquelle entnommene Energiemenge dokumentiert. Im einfachsten Fall kann es sich bei der Erfassungseinrichtung um einen einfachen Zähler handeln, der stets die bis zum Ablesezeitpunkt entnommene Energiemenge angibt, beispielsweise in Joule oder Kilowattstunden. Bevorzugt werden durch die Erfassungseinrichtung aber zusätzlich auch die Zeitpunkte oder Zeiträume einer Aufladung des Energiespeichers erfasst und gespeichert.An electric vehicle according to the invention has a detection device which documents the amount of energy taken from an external power source. In the simplest case, the detection device can be a simple counter, which always indicates the amount of energy removed up to the reading time, for example in joules or kilowatt hours. Preferably, however, the time points or periods of charge of the energy store are additionally detected and stored by the detection device.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass die Erfassungseinrichtung mit einer Schlüsselvorrichtung zusammenwirkt, die zum Freischalten der Schnittstelle erforderlich ist. Die Schlüsselvorrichtung kann beispielsweise ein Dongle sein. Ohne den Dongle lässt sich die Schnittstelle des Elektrofahrzeugs dann nicht frei schalten und der Energiespeicher folglich auch nicht wieder aufladen. Der Dongle kann beispielsweise in den Zündschlüssel des Fahrzeugs integriert sein. Als Schlüsselvorrichtung kann beispielsweise auch eine Karte verwendet werden, die von der Erfassungseinrichtung ausgelesen wird. In einer solchen Karte kann eine charakteristische Kennung, beispielsweise eine Steuernummer oder eine Kontonummer, gespeichert sein.An advantageous development of the invention provides that the detection device cooperates with a key device that is required to unlock the interface. The key device may be a dongle, for example. Without the dongle, the interface of the electric vehicle can not then be released and the energy storage can not be recharged. The dongle may for example be integrated in the ignition key of the vehicle. As a key device, for example, a card can be used, which is read by the detection device. In such a card, a characteristic identifier, such as a tax number or an account number, may be stored.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass die Schlüsselvorrichtung eine charakteristische Kennung überträgt, deren Empfang die Erfassungseinrichtung zum Freischalten der Schnittstelle veranlasst. Bevorzugt wird die charakteristische Kennung drahtlos übertragen, beispielsweise indem ein Transponder als Schlüsselvorrichtung verwendet wird. Die drahtlose Übertragung der charakteristischen Kennung hat den Vorteil einer großen Bequemlichkeit für einen Benutzer und gewährleistet dennoch eine eindeutige Identifikation des Fahrzeugs oder seines Benutzers.An advantageous development of the invention provides that the key device transmits a characteristic identifier whose receipt causes the detection device to unlock the interface. Preferably, the characteristic identifier is transmitted wirelessly, for example by using a transponder as a key device. The wireless transmission of the characteristic identifier has the advantage of great convenience for a user and yet ensures unambiguous identification of the vehicle or its user.
Eine weitere vorteilhafte Weiterbildung der Erfindung sieht vor, dass die Erfassungseinrichtung bei einer Einspeisung von Energie aus dem Energiespeicher in ein externes Stromnetz die abgegebene Energiemenge dokumentiert. Elektrische Energiespeicher, beispielsweise wieder aufladbare Batterien oder Kondensatoren, entladen sich mit der Zeit von selbst. Wenn ein Fahrzeug längere Zeit nicht mehr benutzt werden soll, kann es deshalb vorteilhaft sein, die in dem Energiespeicher des Fahrzeugs gespeicherte Energie wieder in das öffentliche Stromnetz einzuspeisen. Die in einem solchen Fall an ein externes Stromnetz abgegebene Energiemenge kann dann vorteilhaft ebenfalls mit einer erfindungsgemäßen Erfassungseinrichtung dokumentiert werden.A further advantageous embodiment of the invention provides that the detection device documents the amount of energy emitted when feeding energy from the energy store into an external power grid. Electric energy storage devices, for example rechargeable batteries or capacitors, discharge themselves over time. If a vehicle is no longer to be used for a long period of time, it may therefore be advantageous to feed the energy stored in the energy storage device of the vehicle back into the public power grid. The amount of energy delivered to an external power supply in such a case can then advantageously also be documented with a detection device according to the invention.
Die vorliegende Erfindung betrifft neben einem Elektrofahrzeug auch ein Verfahren zum Erfassen des Energieverbrauchs eines Elektrofahrzeugs, wobei die einer externen Energiequelle zum Aufladen des Energiespeichers entnommene Energiemenge erfasst wird, jeder Aufladevorgang dokumentiert wird, indem in einem Datenspeicher ein Wert der Energiemenge gespeichert wird, die der externen Energiequelle entnommen wurde, und der Datenspeicher Teil einer Vorrichtung ist, mit der für einen Aufladevorgang eine Schnittstelle des Fahrzeugs frei geschaltet wird, indem ein Kontakt zwischen der Schnittstelle und dem Energiespeicher geschlossen wird.The present invention relates not only to an electric vehicle but also to a method for detecting the energy consumption of an electric vehicle, wherein the amount of energy taken from an external energy source for charging the energy storage is detected, each charging process is documented by storing in a data memory a value of the amount of energy that is external Power source was removed, and the data storage is part of a device with which is released for a charging an interface of the vehicle by a contact between the interface and the energy storage is closed.
Bevorzugt ist der Inhalt des Datenspeichers verschlüsselt. Vorteilhaft kann so eine Manipulation der in dem Datenspeicher enthaltenen Dokumentation der Aufladevorgänge wesentlich erschwert oder sogar verhindert werden. Die Dokumentation kann deshalb beispielsweise für eine nutzungsabhängige Fahrzeugsteuer verwendet werden.The content of the data memory is preferably encrypted. Advantageously, such a manipulation of the documentation of the charging processes contained in the data memory can be considerably hindered or even prevented. The documentation can therefore be used, for example, for a usage-based vehicle tax.
Die den Datenspeicher enthaltende Vorrichtung kann insbesondere eine Erfassungseinrichtung, welche wie vorstehend beschrieben die aus einer externen Stromquelle entnommene Energiemenge dokumentiert. Der Datenspeicher kann aber auch in einer Schlüsselvorrichtung enthalten sein, die zum Freischalten der Schnittstelle erforderlich ist.In particular, the device containing the data memory can record a detection device which, as described above, documents the amount of energy taken from an external power source. The data memory can also be contained in a key device that is required to unlock the interface.
