Verfahren und Vorrichtung zum manipulationssicheren Aufladen eines Elektrofahrzeuges über eine Ladesäule Method and device for tamper-proof charging of an electric vehicle via a charging station
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum manipulationssicheren Aufladen eines Elektro- fahrzeuges über eine Ladesäule. Weithin bekannt ist eine Abrechnung von Strombezug auf einem Parkplatz über Parkscheine oder direkten Münzeinwurf, d.h. der Strombedarf wird direkt vor Ort bezahlt. Darüber hinaus sind Parkscheinautomaten mit Elektrotankstellen bekannt, wobei der Zugriff auf die Ladestation über einen mechanischen Schlüssel geregelt wird und eine Berechtigung des Elektro- fahrzeuges über eine Vignette von einer Aufsichtsperson geprüft werden kann. The present invention relates to a method and a device for tamper-proof charging of an electric vehicle via a charging station. Well-known is a billing of electricity purchase in a parking lot via parking tickets or direct coin slot, i. The electricity requirement is paid directly on site. In addition, parking ticket machines are known with electric filling stations, the access to the charging station is controlled by a mechanical key and authorization of the electric vehicle can be checked by a vignette by a supervisor.
Die JP 2008042984 offenbart, dass an einer Stromtankstelle eine Vehicle-ID eines Fahrzeuges ausgelesen wird und mittels eines Servers überprüft wird, ob diese Vehicle-ID des Fahr¬ zeuges registriert ist. Davon abhängig ist eine Ausstellung einer Berechtigung zum Laden des Fahrzeuges an der Stromtankstelle . JP 2008042984 discloses that a vehicle ID of a vehicle is read out at a charging station and is checked by means of a server, whether the vehicle ID of the driving ¬ tool is registered. Dependent on this is an issue of an authorization to charge the vehicle at the charging station.
Die CN 201018298 Y beschreibt ein drahtloses Übertragungsge¬ rät zur Verwendung von Ladeparametern für das Laden eines Elektrofahrzeuges , wobei die Ladeparameter drahtlos übertra¬ gen werden. Das beschriebene drahtlose Übertragungsgerät um- fasst einen Signalprozessor, eine Kommunikationseinrichtung und eine Speichereinheit. The CN 201018298 Y describes a wireless Übertragungsge ¬ recommends the use of charging parameters for charging an electric vehicle, said charging parameters are wirelessly übertra ¬ gen. The wireless transmission device described comprises a signal processor, a communication device and a memory unit.
Elektrofahrzeuge können an Ladestationen, ähnlich einer Tankstelle, aufgeladen werden. Dabei können verschiedene Bezahl- modalitäten genutzt werden wie etwa über eine GuthabenkarteElectric vehicles can be charged at charging stations, similar to a gas station. Various payment modalities can be used, such as a prepaid card
( ' Prepaid cards ' ) , über eine direkte Abbuchung oder über eine Kreditkarte. Dabei ist es wünschenswert, einen Betrugsversuch verhindern zu können. Insbesondere, da die Ladestation im Ge- gensatz zu herkömmlichen Tankstellen eher unbemannt ist, muss möglichen Betrugsversuchen vorgebeugt werden. Wird ein Elekt- rofahrzeug geladen, möchte auf der einen Seite der Besitzer des Elektrofahrzeuges sicherstellen, dass er nur für die beim Elektrofahrzeug angekommene Energiemenge bezahlt. Auf der an¬ deren Seite möchte ein Ladestationsbetreiber sicherstellen, dass nur der bezahlende Kunde den angeforderten Strom erhält. Dabei kann es vorkommen, dass die Ladestation von einem aus der Sicht des Energielieferanten oder des Kunden nur teilwei- se vertrauenswürdigen Betreiber angeboten wird. Es wird ein Verfahren benötigt, bei dem sichergestellt wird, dass ein Kunde nur für die empfangene Leistung bezahlt, unabhängig da¬ von, ob die Ladestation vertrauenswürdig ist oder nicht. Dar¬ über hinaus soll sichergestellt werden, dass ein Betreiber erkennen und darauf geeignet reagieren kann, wenn Strom an bestimmten Ladestationen ohne Bezahlung abgegriffen wird. ('Prepaid cards'), via direct debit or credit card. It is desirable to be able to prevent a fraud attempt. In particular, since the charging station in the In contrast to conventional petrol stations, it is rather unmanned that possible fraud must be prevented. When an electric vehicle is being charged, on the one hand, the owner of the electric vehicle wants to make sure that he only pays for the amount of energy arrived at the electric vehicle. On the other side, a charging station operator wants to ensure that only the paying customer receives the requested electricity. It may happen that the charging station is offered by an operator who is only partially trustworthy from the point of view of the energy supplier or the customer. What is needed is a method, in which ensures that a customer only pays for the service received, regardless ¬ because of whether the charging station is trusted or not. Dar ¬ is to ensure that an operator recognize and respond to suitable, if current at specific charging stations is tapped without pay beyond.
Es ist daher eine Aufgabe der vorliegenden Erfindung, ein sicheres Verfahren und eine sichere Vorrichtung zum Aufladen eines Elektrofahrzeuges zur Verfügung zu stellen, bei dem ge¬ währleistet wird, dass die tatsächlich transferierte Energie¬ mengen von allen Beteiligten erfasst werden. It is therefore an object of the present invention to provide a secure method and a secure device for charging an electric vehicle available is ensured at the ge ¬ that the actually transferred energy ¬ quantities are recognized by all parties.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren zum manipulationssicheren Aufladen eines Elektrofahrzeuges über eine Ladesäule mit den Merkmalen des Patentanspruchs 1 und durch eine Vorrichtung gemäß Patentanspruch 15 gelöst.
