5. System for supplying power to an electric vehicle on a parking space, according to claim 2, characterized in that, after the supplying of power has ended, the amount corresponding to the power consumption can be transmitted to the portable device or mobile phone in the form of a unidimensional or two-dimensional barcode by means of a renewed RFID or NFC interaction between the user'"'"'s portable device or mobile phone and the RFID or NFC-enabled device of the charging station, wherein, when the parking space is exited, the barcode is read out by the payment device and the amount to be paid is displayed, and wherein the amount can be paid by using credit card data or bank connection data stored in the mobile device or mobile phone or using a direct payment by means of the telephone number of the mobile phone.

6. System for supplying power to an electric vehicle on a parking space, according to claim 1, characterized in that the means for identifying or detecting the vehicle comprise a device for detecting the license plate of the vehicle, wherein the supplying of power can be activated after the license plate has been detected, wherein, when the parking space is exited, the vehicle is identified on the basis of the same device, or a further device, for detecting license plates, and the amount to be paid, which corresponds to the power consumption, is displayed on the payment device.

7. System for supplying power to an electric vehicle on a parking space, according to claim 1, characterized in that the means for identifying or detecting the vehicle comprise a device for setting up a wireless network connection or a WLAN device via which a connection can be set up to a device for setting up a wireless network connection or a WLAN device of the vehicle or a portable device or a mobile phone of the user, by means of which a unique assignment number of the vehicle can be transmitted to the means for identifying or detecting the vehicle, wherein the supplying of power can be activated after the assignment number has been transmitted.

8. System for supplying power to an electric vehicle on a parking space, according to claim 7, characterized in that the assignment number is the license plate of the vehicle, the mobile phone number of the mobile phone, the number of the SIM card of the mobile phone or a number which is to be allocated via the wireless network connection or WLAN connection and is stored in a computer of the vehicle or in the mobile device or in the mobile phone.

9. System for supplying power to an electric vehicle on a parking space, according to claim 7, characterized in that, after the supplying of power has ended, the amount to be paid can be determined when the parking space is exited by means of a wireless network connection or a WLAN connection between a computer of the vehicle or the user'"'"'s mobile device or mobile phone and the payment device on the basis of the assignment number, wherein the amount to be paid can be paid using credit card or bank connection data stored in the computer of the vehicle or in the user'"'"'s mobile device or mobile phone or using a direct payment by means of the telephone number of the mobile phone, wherein the consumption information and the assignment number of the vehicle can be transmitted to the payment device, directly or via a central server which is connected to the payment device, from the means for identifying or detecting the vehicle.

10. System for supplying power to an electric vehicle on a parking space, according to claim 1, characterized in that if the supplying of power to the electric vehicle takes place via a cable which is to be connected to the vehicle, the cable is embodied in such a way that, in addition to the power line, a data line is also provided via which the data which are used for identifying or detecting the vehicle can be transmitted from a computer of the vehicle to the charging station, or in that the transmission of the data which is used for identifying or detecting the vehicle is transmitted from a computer of the vehicle to the charging station via the power line of the cable.

11.
