Abstract

Method, device and system for charging electric vehicles. Carrying out 28 on the vehicle side a charging process at a charging station, emitting 30 on the vehicle side an item of information about the charging process and receiving 24 on the vehicle side a current contract key after the emission on the vehicle side of the information about the charging process are proposed for identifying an electric vehicle to a billing centre.

Claims

1. Method for identifying an electric vehicle to a billing centre, comprising the steps of:

a) carrying out on a vehicle side a charging process at a charging station,

b) emitting on the vehicle side an item of information about the charging process,

c) receiving on the vehicle side a current contract key after the emission on the vehicle side of the information about the charging process.

2. Method of claim 1, wherein the charging process is initiated on the vehicle side and in that an item of information about the initiated charging process is emitted.

3. Method of claim 2, wherein the current contract key is received after the emission of the information about the initiated charging process.

4. Method of claim 1, wherein a vehicle-side memory is checked for a stored contract key and in that, in the event of a negative check, the current contract key is written into the memory and is used as the stored contract key.

5. Method of claim 3, wherein a vehicle-side memory is checked for a stored contract key and in that, in the event of a positive check, the stored contract key remains in the memory.

6. Method of claim 1, wherein the current contract key is stored together with a key status in vehicle-side memory.

7. Method of claim 1, wherein at least one stored contract key and an item of information about an amount of energy procured are emitted on the vehicle side.

8. Method of claim 1, wherein the current contract key contains a pair made up of a public contract key and a private contract key.

12. Device, in particular for carrying out a method according to claim 1, the device comprising:

charging means configured for carrying out on a vehicle side a charging process at a charging station

communication means configured for emitting on the vehicle side an item of information about the charging process and for receiving on the vehicle side a current contract key after the emission on the vehicle side of the information about the charging process,

memory means configured for storing a current contract key, and

comparison means configured for comparing a received current contract key to a stored contract key.

13. System with a device of claim 12 and a billing centre, comprising:

communication means configured for receiving information about a charging process from an electric vehicle and for emitting a current contract key, and

processing means configured for enabling a current contract key.

9. Method for identifying an electric vehicle in a billing centre comprising the steps of:

receiving on a billing centre side information about a charging process of an electric vehicle,

enabling on the billing centre side a current contract key, and

emitting on the billing centre side the current contract key.

10. Method of claim 9, wherein information about an initiated charging process is received on the billing centre side and in that the current contract key is emitted after the reception of the information about the initiated charging process.

11. Method of claim 9, wherein the current contract key is pushed to the vehicle.

14. Device, in particular for carrying out a method according to claim 9, the device comprising:

charging means configured for carrying out on a vehicle side a charging process at a charging station

communication means configured for emitting on the vehicle side an item of information about the charging process and for receiving on the vehicle side a current contract key after the emission on the vehicle side of the information about the charging process,

memory means configured for storing a current contract key, and

comparison means configured for comparing a received current contract key to a stored contract key.
