Abstract

A method for balancing electrical grid production with electrical grid demand according to an exemplary aspect of the present disclosure includes, among other things, controlling an electrified vehicle prior to and during an inductive roadway event to either conserve a state of charge of a battery pack in response to a first grid condition of an electrical grid or deplete the state of charge of the battery pack in response to a second grid condition of the electrical grid.

First claim

What is claimed is:

1. A method for balancing electrical grid production with demand, comprising:
controlling an electrified vehicle prior to and during an inductive roadway event in which the electrified vehicle travels along an inductive roadway to conserve a state of charge of a battery pack in response to a first grid condition of an electrical grid and deplete the state of charge of the battery pack in response to a second grid condition of the electrical grid; and
controlling an inductive charging system of the electrified vehicle to either send electrical energy to the inductive roadway or accept electrical energy from the inductive roadway while the electrified vehicle is traveling along the inductive roadway,
wherein when controlling the electrified vehicle and the inductive charging system, both prior to and during the inductive roadway event, the electrified vehicle is off-plug and a drive wheel of the electrified vehicle is being driven to propel the electrified vehicle.

2. The method as recited in claim 1 , wherein the first grid condition is an energy shortage of the electrical grid and the second grid condition is an energy surplus of the electrical grid.

3. The method as recited in claim 2 , comprising adding power from the battery pack to the electrical grid during the inductive roadway event when the electrical grid has the energy shortage.

4. The method as recited in claim 2 , comprising accepting power from the electrical grid to charge the battery pack during the inductive roadway event when the electrical grid has the energy surplus.

5. The method as recited in claim 1 , wherein the controlling step includes calculating an amount of power needed to meet an electrical need of the electrical grid based on whether the electrical grid anticipates an electrical shortage or an electrical surplus.

6. The method as recited in claim 1 , comprising:
confirming whether a wireless grid signal has been received by the electrified vehicle from the electrical grid.

7. The method as recited in claim 6 , comprising:
determining whether the wireless grid signal indicates an energy shortage or an energy surplus.

8. The method as recited in claim 7 , wherein, when the wireless grid signal indicates an energy shortage, the controlling step includes:
increasing a power output of a power source or increasing a run time of the power source during the inductive roadway event.

9. The method as recited in claim 8 , comprising:
adding energy from the battery pack to the inductive roadway and then from the inductive roadway to the electrical grid to address the energy shortage.

10. The method as recited in claim 7 , wherein, when the wireless grid signal indicates an energy surplus, the controlling step includes:
decreasing a power output of a power source or decreasing a run time of the power source during the inductive roadway event.

11. The method as recited in claim 10 , comprising:
delivering power from the electrical grid to the inductive roadway and then from the inductive roadway to the electrified vehicle to charge the battery pack during the inductive roadway event.

12. The method as recited in claim 1 , comprising:
actuating a power source ON during the inductive roadway event in response to an energy shortage condition of the electrical grid.

13. The method as recited in claim 1 , comprising:
decreasing a power output of a power source or decreasing a run time of the power source during the inductive roadway event in response to an energy surplus condition of the electrical grid.

14. An electrified vehicle, comprising:
a set of drive wheels;
a power source configured to selectively power said drive wheels;
a battery pack configured to selectively power said drive wheels; and
a control system configured with instructions for adjusting operation of said power source while traveling on an inductive roadway in a manner that influences an electrical grid.

15. The electrified vehicle as recited in claim 14 , wherein said control system is configured to receive a wireless grid signal from said electrical grid, said wireless grid signal including said instructions.

16. The electrified vehicle as recited in claim 14 , comprising an inductive charging system configured to either send electrical energy to said inductive roadway or receive electrical energy from said inductive roadway.

17. The electrified vehicle as recited in claim 14 , wherein said control system is configured to run said power source during an energy shortage condition of said electrical grid and restrict operation of said power source during an energy surplus condition of said electrical grid.

18. The electrified vehicle as recited in claim 14 , wherein said power source is an engine or a fuel cell.

19. A method, comprising:
increasing a power output of an engine of an electrified vehicle traveling along an inductive roadway in response to an electrical grid energy shortage;
decreasing the power output of the engine in response to an electrical grid energy surplus;
wherein increasing the power output conserves a state of charge of a battery pack of the electrified vehicle and decreasing the power output reduces the state of charge of the battery pack.

20. The method as recited in claim 1 , wherein the inductive roadway event involves traveling greater than a negligible distance along the inductive roadway.

21. The method as recited in claim 1 , wherein the inductive roadway includes a network of interconnected charging modules that are either embedded inside the inductive roadway or fixated overhead of the inductive roadway.

22. The method as recited in claim 1 , wherein the controlling step includes:
increasing a power output of an engine of the electrified vehicle prior to the inductive roadway event in response to an electrical grid shortage; and
decreasing the power output of an engine of the electrified vehicle prior to the inductive roadway event in response to an electrical grid surplus.

23. The electrified vehicle as recited in claim 14 , wherein adjusting said operation of said power source includes increasing or decreasing a run time of said power source.

24. The electrified vehicle as recited in claim 14 , wherein adjusting said operation of said power source includes both increasing or decreasing a power output of said power source and increasing or decreasing a run time of said power source.

25. The method as recited in claim 1 , comprising:
communicating information from a control system of the electrified vehicle to an inductive roadway interface associated with the inductive roadway during the inductive roadway event,
wherein the information includes vehicle location data, vehicle direction and velocity data, expected drive route data, and charging data.
