Abstract

A method for influencing the efficiency of an electrical grid includes coordinating operation of a first electrified vehicle and a second electrified vehicle traveling along an inductive roadway and having opposite power needs in a manner that influences an amount of energy supplied by the electrical grid during an inductive roadway event.

Claims

1. A method for influencing the efficiency of an electrical grid, comprising:

coordinating operation of a first electrified vehicle and a second electrified vehicle traveling along an inductive roadway and having opposite power needs in a manner that influences an amount of energy supplied by the electrical grid during an inductive roadway event.

2. The method as recited in claim 1, wherein the opposite power needs indicate that one of the first electrified vehicle and the second electrified vehicle needs to discharge excess regenerative energy to the inductive roadway and the other of the first electrified vehicle and the second electrified vehicle needs to receive power from the inductive roadway.

3. The method as recited in claim 1, comprising:

communicating vehicle data from both the first electrified vehicle and the second electrified vehicle to an inductive roadway interface and the electrical grid.

4. The method as recited in claim 1, wherein coordinating the operation of the first electrified vehicle and the second electrified vehicle includes at least one of providing more or less battery power, engine power or wheel torque.

5. The method as recited in claim 1, comprising:

adding energy from the first electrified vehicle to the inductive roadway and then from the inductive roadway to the second electrified vehicle if the first electrified vehicle is traveling along an area of expected power absorption of the inductive roadway and the second electrified vehicle is traveling along an area of expected power usage of the inductive roadway.

6. The method as recited in claim 1, comprising:

prior to coordinating operation, determining whether the first electrified vehicle and the second electrified vehicle are traveling along the inductive roadway and are exhibiting the opposite power needs.

7. The method as recited in claim 1, comprising:

determining a common power necessary to meet a power demand of both the first electrified vehicle and the second electrified vehicle.

8. The method as recited in claim 1, wherein coordinating operation of the first electrified vehicle and the second electrified vehicle includes:

controlling an inductive charging system of the first electrified vehicle and the second electrified vehicle to either send electrical energy to the inductive roadway or accept electrical energy from the inductive roadway.

9. The method as recited in claim 1, wherein coordinating operation of the first electrified vehicle and the second electrified vehicle includes:

discharging energy from the first electrified vehicle traveling on a first section of the inductive roadway to an inductive roadway interface; and

powering a second electrified vehicle traveling on a second section of the inductive roadway using the energy discharged from the first electrified vehicle.

10. The method as recited in claim 9, comprising:

adding additional energy to the second electrified vehicle from the electrical grid if an electrical shortage is still occurring on the second electrified vehicle after powering the second electrified vehicle using the energy discharged from the first electrified vehicle.

11. The method as recited in claim 9, comprising:

discharging additional energy from the first electrified vehicle to the inductive roadway if an electrical surplus is still occurring on the first electrified vehicle after powering the second electrified vehicle using the energy discharged from the first electrified vehicle.

12. An electrified vehicle, comprising:

a set of drive wheels;

an energy storage device configured to selectively power said drive wheels; and

a control system configured with instructions for coordinating a transfer of energy between the electrified vehicle and other electrified vehicles traveling along an inductive roadway and which have opposite power needs from the electrified vehicle.

13. The electrified vehicle as recited in claim 12, wherein said energy storage device is a battery pack.

14. The electrified vehicle as recited in claim 12, wherein said control system is configured to adjust operation of the electrified vehicle to either accept energy from or discharge energy to an inductive roadway interface.

15. The electrified vehicle as recited in claim 12, wherein said control system is configured to detect said other electrified vehicles traveling on said inductive roadway prior to coordinating said transfer of energy.

16. The electrified vehicle as recited in claim 12, wherein said electrified vehicle includes an inductive charging system in communication with an inductive roadway interface to transfer said energy.

17. The electrified vehicle as recited in claim 12, wherein said opposite power needs indicate that said electrified vehicle or one of said other electrified vehicles needs to discharge excess regenerative energy to said inductive roadway and the other of the electrified vehicle and said one of said other electrified vehicles needs to receive power from the inductive roadway.

18. The electrified vehicle as recited in claim 12, wherein said control system is configured to receive a wireless grid signal from an electrical grid.

19. The electrified vehicle as recited in claim 12, comprising a power source configured to selectively power said drive wheels.

20. The electrified vehicle as recited in claim 19, wherein said power source is an engine or a fuel cell.
