Abstract

A method for planning a charging of an electrical vehicle comprises receiving a request for charging from an electrical vehicle at a charging pole, determining a charging time slot for the electrical vehicle based on the request for charging, scheduling the charging time slot for the electrical vehicle, predicting a load requirement for the charging pole based on the request for charging and the charging time slot, and sending the load requirement to a grid operator supplying the charging pole with electrical power.

Claims

1. A method for planning a charging of an electrical vehicle, the method comprising:

receiving a request for charging from an electrical vehicle at a first charging pole;

determining a charging time slot for the electrical vehicle based on the request for charging;

scheduling the charging time slot for the electrical vehicle;

predicting a load requirement for the first charging pole based on the request for charging and the charging time slot;

receiving a load requirement from at least one second charging pole;

exchanging the charging time slot with another charging time slot of the at least one second charging pole to optimize an overall load requirement;

sending the load requirements to a grid operator supplying the first charging pole and the at least one second charging pole with electrical power.

2. The method of claim 1,

wherein the load requirement comprises a required electrical power for a future time interval.

3. The method of claim 1, further comprising:

determining the charging time slot based on the load requirement of the second pole.

4. The method of claim 1,

wherein the overall load requirement of the first charging pole and the at least one second charging pole is optimized by time shifting the charging time slot or adapting the charging profile of the charging time slot to the load requirement of the second charging pole.

5. The method of claim 1,

wherein the overall load requirement is optimized such that a maximal load requirement is reduced;

or

wherein the overall load requirement is optimized such that timely changes in the overall load requirement are reduced.

6. The method according to claim 1, further comprising:

redirecting the electrical vehicle to the second charging pole based on the load requirement of the second charging pole.

7. The method of claim 1,

wherein the request for charging comprises at least one of a current position of the electrical vehicle, a current speed of the electrical vehicle, a battery level of the electrical vehicle, a battery size of the electrical vehicle, an expected arrival time of the electrical vehicle, and a destination of the electrical vehicle.

8. The method of claim 1, further comprising:

sending a response for charging with a charging time to the electrical vehicle;

receiving an agreement for charging from the electrical vehicle;

scheduling the charging time slot after receiving the agreement for charging.

9. The method of claim 7, further comprising:

reserving the charging time slot for charging for a predefined duration, after sending the response for charging.

10. The method of claim 8,

wherein the response for charging comprises at least one of the charging time slot, a charging time, a charging duration, an estimated arrival time, and a price for charging.

11. The method of claim 1,

wherein at least one of the request for charging, a response for charging or an agreement for charging are transmitted between the charging pole and the electrical vehicle via a data communication network.

12. The method of claim 1, further comprising:

offering a chain of charging poles along a route of the electrical vehicle.

15. The method of claim 2, further comprising:

determining the charging time slot based on the load requirement of the second pole.

16. The method of claim 15, wherein an overall load requirement of the first charging pole and the at least one second charging pole is optimized by time shifting the charging time slot or adapting the charging profile of the charging time slot to the load requirement of the second charging pole.

17. The method of claim 16,

wherein the overall load requirement is optimized such that a maximal load requirement is reduced;

or

wherein the overall load requirement is optimized such that timely changes in the overall load requirement are reduced.

18. The method according to claim 4, further comprising:

redirecting the electrical vehicle to the second charging pole based on the load requirement of the second charging pole.

19. The method according to claim 5, further comprising:

redirecting the electrical vehicle to the second charging pole based on the load requirement of the second charging pole.

13. A charging pole, comprising:

a charging device for charging an electrical vehicle;

a communication device adapted for communication with an electrical vehicle and an operator of an electrical grid supplying the charging pole with electrical energy;

a computing device adapted for controlling a charging of the electrical vehicle via the charging device the computing device operable to

receive a request for charging from the electrical vehicle at the charging pole;

determine a charging time slot for the electrical vehicle based on the request for charging;

schedule the charging time slot for the electrical vehicle;

predict a load requirement for the charging pole based on the request for charging and the charging time slot;

receive a load requirement from at least one second charging pole;

exchange the charging time slot with another charging time slot of the at least one second charging pole to optimize an overall load requirement;

send the load requirements to the operator supplying the charging poles with electrical power.

14. A charging system comprising a plurality of charging poles according to claim 13, wherein the charging poles are communicatively interconnected via a data communication network.
