Abstract

A method for sending a vehicle-to-grid (V2G) request that includes receiving a V2G request for a specific geographical region; determining which of a plurality of vehicles are in the specific geographic region; determining a subset of the plurality of vehicles located in the specific geographic region that meet at least one criteria to join the V2G request, wherein the at least one criteria uses historical data of the plurality of vehicles to reduce battery degradation of the plurality of vehicles; and sending a signal to the subset of the plurality of vehicles to join the V2G request.

Claims

1. A method for sending a vehicle-to-grid (V2G) request comprising:

receiving a V2G request for a specific geographical region;

determining which of a plurality of vehicles are in the specific geographic region;

determining, based on historical data of the plurality of the vehicles and at least one of a number of discharge cycles and a frequency of usage, a subset of the plurality of vehicles located in the specific geographic region to discharge electrical energy stored therein; and

sending a signal to the subset of the plurality of vehicles to cause the subset of the plurality of vehicles to discharge the stored electrical energy.

2. The method of claim 1, comprising forecasting an amount of energy that the plurality of vehicles can provide to utility companies or aggregators acting on behalf of the utility companies in the specific geographic region based on the historical data.

3. The method of claim 2, comprising notifying the utility companies in the specific geographic region of the amount of energy forecasted.

4. The method of claim 1, comprising communicating to at least one of the plurality of vehicles to prevent the discharging of electrical energy based on the historical data to prevent battery degradation.

5. The method of claim 1, wherein determining a subset of the plurality of vehicles is further based on at least one of:

an operating temperature, State of Charge (SOC), a number of trips below a predefined mileage, a vehicle range based on a fully charged battery pack, or condition and degree of degradation of the battery pack.

6. The method of claim 5, wherein a minimum required current SOC is at least 50% of a full charge.

7. The method of claim 5 wherein if the vehicle range based on a fully charged battery pack is less than a defined threshold, the number of discharge cycles exceeds a defined limit, or the condition and degree of degradation of the battery pack exceeds a defined threshold, the vehicle is ineligible to join the V2G request.

8. The method of claim 1, comprising:

verifying contributions of stored energy from each of the subset of the plurality of vehicles to the electric grid; and

recording the contributions in a database.

9. A system for vehicle-to-grid (V2G) priority based selection comprising:

a network configured for communication among one or more utility companies, a vehicle company, and a plurality of vehicles manufactured by the vehicle company;

at least one server with a database containing information for the plurality of vehicles, wherein the at least one server has a processor configured to access the database and to execute a set of program instructions causing the processor to;

receive a V2G request for a specific geographical region;

determine a subset of a plurality of vehicles that meet at least one of a plurality of criteria to discharge electrical energy stored therein, wherein the plurality of criteria includes at least one of a number of discharge cycles and a frequency of usage, wherein current and historical data of the plurality of vehicles determines eligibility for the V2G request; and

send a signal to the subset of the plurality of vehicles to cause the subset of the plurality of vehicles to discharge the stored electrical energy.

10. The system of claim 9, wherein determining the subset of the plurality of vehicles is further based on at least one of:

an operating temperature, a current vehicle location, State of Charge (SOC), a number of trips below a predefined mileage, a vehicle range based on a fully charged battery pack, or degree of degradation of the battery pack.

11. The system of claim 10, wherein the program instructions executed by the processor, causes the processor to determine ineligibility to join the V2G request when the current location is outside a predefined boundary and at least one of:

the vehicle range based on a fully charged battery pack is less than a defined threshold, the number of discharge cycles exceeds a defined limit, or the degree of degradation of the battery pack exceeds a defined threshold, the vehicle is ineligible to join the V2G request.

12. The system of claim 9, wherein the program instructions executed by the processor, causes the processor to forecast an amount of energy that the plurality of vehicles can provide to the utility companies or aggregators on behalf of the utility companies in the specific geographic region based on the current and historical data.

13. The system of claim 9, wherein the program instructions executed by the processor, causes the processor to notify the utility companies or the aggregators on behalf of the utility companies in the geographic region of the amount of energy forecasted.

14. The system of claim 9, wherein the program instructions executed by the processor, causes the processor to communicate to at least one of the plurality of vehicles to limit V2G participation based on the current and historical data to prevent further battery degradation.

15. A method for a vehicle-to-grid (V2G) priority based selection comprising:

receiving a request for a plurality of vehicles manufactured by a vehicle company based on a geographic region;

reviewing a database of last known vehicle status to determine a last known position for each of the plurality of vehicles in the database;

determining which of the plurality of vehicles are in the geographic area specified in the request;

determining a subset of the plurality of vehicles that are in the geographic area that meet at least one of a plurality of criteria established by the vehicle company to reduce battery degradation including a number of discharge cycles and a frequency of usage, wherein current and historical data is used to determine the subset;

sending a signal to cause the subset to discharge electrical energy stored in the subset of the plurality of vehicles and

communicating to at least one of the plurality of vehicles to prevent the discharging of electrical energy based on the current and historical data of the at least one of the plurality of vehicles to prevent further battery degradation.

16. The method of claim 15, comprising:

forecasting an amount of energy that the plurality of vehicles can provide to utility companies or aggregators on behalf of the utility companies in the geographic region based on the historical data; and

notifying the utility companies or aggregators on behalf of the utility companies in the geographic region of the amount of energy forecasted.

17. The method of claim 15, wherein determining the subset of the plurality of vehicles is further based on at least one of:

an operating temperature, a current vehicle location, State of Charge (SOC), a number of trips below a predefined mileage, a vehicle range based on a fully charged battery pack, or condition and degree of degradation of the battery pack.

18. The method of claim 17 wherein if the vehicle range based on a fully charged battery pack is less than a defined threshold, the number of discharge cycles exceeds a defined limit, or the condition and degree of degradation of the battery pack exceeds a defined threshold, the vehicle is ineligible to join the V2G request.

19. The method of claim 15, further comprising:

verifying contributions of stored energy from each of the subset of the plurality of vehicles to the electric grid; and
