Abstract

Method, system and device for determining quantities of power by registering on the vehicle side a quantity of power exchanged with a power point 12, transmission on the vehicle side of information concerning the first quantity of power, registering on the power point side of a total quantity of power formed from the sum of the first quantity of power and also a second quantity of power made available by the power point 12 independently of the electric vehicle 2, subtraction of the first quantity of power received by the vehicle 2 from the total quantity of power in order to determine the second quantity of power.

Claims

1. Method for determining quantities of power exchanged between a vehicle on a vehicle side and a power point on a power point side, comprising:

registering on the vehicle side a first quantity of power exchanged with the power point;

sending out on the vehicle side information concerning the first quantity of power;

integrally registering on the power point side a total quantity of power formed from the sum of the first quantity of power and also a second quantity of power made available by the power point independently of the vehicle;

subtraction of the first quantity of power received by the vehicle from the total quantity of power in order to determine the second quantity of power.

2. Method of claim 1, further comprising sending out on the vehicle side a vehicle identifier which identifies the vehicle together with information concerning the first quantity of power.

3. Method of claim 1, further comprising reception on the power point side of information concerning the first quantity of power together with a vehicle identifier.

4. Method of claim 1, wherein the step of subtraction of the first quantity of power received from the vehicle from the total quantity of power in order to determine the second quantity of power occurs on the power point side.

5. Method of claim 4, further sending out on the power point side of information concerning the second quantity of power together with a power point identifier and of information concerning the first quantity of power together with a vehicle identifier received on the power point side.

6. Method of claim 5, further comprising reception of the information concerning the second quantity of power together with the power point identifier and of the information concerning the first quantity of power together with the vehicle identifier in a centrally arranged computer.

7. Method of claim 6, further comprising creation of a first data set comprising information concerning the second quantity of power and the power point identifier and also of a second data set comprising information concerning the first quantity of power and the vehicle identifier in the centrally arranged computer.

8. Method of claim 1, further comprising reception on the vehicle side of a power point identifier transmitted by the power point.

9. Method of claim 8, further comprising sending out on the vehicle side of information concerning the first quantity of power together with the power point identifier and a vehicle identifier.

10. Method of claim 9, further comprising reception of information concerning the first quantity of power together with the power point identifier and the vehicle identifier in a centrally arranged computer.

11. Method of claim 1, further comprising sending out on the power point side of information concerning the total quantity of power together with a power point identifier.

12. Method of claim 11, further comprising reception of the information concerning the total quantity of power together with the power point identifier in a centrally arranged computer.

13. Method of claim 12, further comprising subtraction of the first quantity of power received from the vehicle from the total quantity of power in order to determine the second quantity of power in the centrally arranged computer.

14. Method of claim 13, further comprising creation of a first data set comprising information concerning the second quantity of power and the power point identifier and also of a second data set comprising information concerning the first quantity of power and a vehicle identifier in the centrally arranged computer.

15. System for determining quantities of power exchanged between a vehicle on a vehicle side and a power point on a power point side, comprising:

a first meter means on the vehicle side configured to register a first quantity of power exchanged with the power point on the power point side,

sending means on the vehicle side configured to send out information concerning the first quantity of power,

a second meter means on the power point side configured to integrally register a total quantity of power formed from the sum of the first quantity of power and also a second quantity of power made available by the power point independently of the vehicle, and

computing means configured to subtract the first quantity of power received by the vehicle from the total quantity of power in order to determine the second quantity of power.

16. System of claim 15, wherein the first meter means is calibrated.

17. System of claim 15, wherein the second meter means is configured to remotely read a power point identifier and the total quantity of power.

18. System of claim 15, wherein the computing means are arranged in one of the power point or in a centrally arranged computer.

19. Device, comprising:

receiving means configured to receive information concerning a first quantity of power together with a vehicle identifier and also a power point identifier together with information concerning a second quantity of power or a total quantity of power, and

data processing means configured to create a first data set comprising information concerning a second quantity of power and the power point identifier and also a second data set comprising information concerning the first quantity of power and the vehicle identifier, and

computing means configured to subtract the first quantity of power received by the vehicle from the total quantity of power in order to determine the second quantity of power.
