Abstract

There is a provided a system and a computer-implemented method for reducing electric consumption by an electric vehicle connected to a charging station. The method includes: providing a wireless network for communication between an electric vehicle and a tracking server operated by a trusted entity; collecting, on the tracking server, user and location information for charging electric vehicles (EVs); receiving, at the tracking server, a demand response signal comprising consumption reduction information including sector and time period information from a utility; identifying, at the tracking server, electric vehicles charging in the sector based on each EV'"'"'s location information; and transmitting, from the tracking server, a charge interruption signal to the identified electric vehicles.

Claims

1. A computer-implemented method for reducing electric consumption by an electric vehicle connected to a charging station, the method comprising:

providing a wireless network for communication between an electric vehicle and a tracking server operated by a trusted entity;

collecting, on the tracking server, user and location information for charging electric vehicles (EVs);

receiving, at the tracking server, a demand response signal comprising consumption reduction information including sector and time period information from a utility;

identifying, at the tracking server, electric vehicles charging in the sector based on each EV'"'"'s location information; and

transmitting, from the tracking server, a charge interruption signal to the identified electric vehicles.

2. The method of claim 1, further comprising transmitting, from the tracking server, a charge interruption message to a user of each of the identified electric vehicles.

3. The method of claim 1, further comprising:

transmitting, from the tracking server, a charge interruption request to a user of each of the identified electric vehicles;

receiving, at the tracking server, a disapproval of the charge interruption request within a response period from the user of one of the identified electric vehicles; and

unidentifying the one of the identified electric vehicles as one of the identified electric vehicles.

4. The method of claim 1, further comprising:

transmitting, from the tracking server, a charge interruption request to a user of each of the identified electric vehicles;

receiving, at the tracking server, a disapproval of the charge interruption request after a response period from the user of one of the identified electric vehicles; and

resuming the charging of the one of the identified electric vehicles.

5. The method of claim 1, further comprising unidentifying one of the identified electric vehicles when a State of Charge (SOC) of the one of the identified electric vehicles is less than a minimum SOC.

6. The method of claim 1, further comprising unidentifying one of the identified electric vehicles when historical data indicates usage of the one of the identified electric vehicles is imminent.

7. The method of claim 1, further comprising confirming, at the tracking server, a charge interruption of each of the identified electric vehicles.

8. The method of claim 7, further comprising awarding an incentive or credit to each of the identified electric vehicles confirming charge interruption.

9. The method of claim 1, wherein the transmitting of the charge interruption signal is initiated prior to a charge interruption start time specified in the time period information.

10. The method of claim 1, further comprising transmitting a charge resumption signal after a charge interruption end time specified in the time period information.

11. A vehicle system for reducing electric consumption by an electric vehicle connected to a charging station, the system comprising:

a tracking server operated by a trusted entity; and

a wireless network for communicating between an electric vehicle and the tracking server,

wherein the tracking server is configured to

collect user and location information for charging electric vehicles (EVs);

receive a demand response signal comprising consumption reduction information including sector and time period information from a utility;

identify electric vehicles charging in the sector based on each EV'"'"'s location information; and

transmit a charge interruption signal to the identified electric vehicles.

12. The system of claim 11, wherein the tracking server is further configured to transmit a charge interruption message to a user of each of the identified electric vehicles.

13. The system of claim 11, wherein the tracking server is further configured to

transmit a charge interruption request to a user of each of the identified electric vehicles;

receive a disapproval of the charge interruption request within a response period from the user of one of the identified electric vehicles; and

unidentify the one of the identified electric vehicles as one of the identified electric vehicles.

14. The system of claim 11, wherein the tracking server is further configured to

transmit a charge interruption request to a user of each of the identified electric vehicles;

receive a disapproval of the charge interruption request after a response period from the user of one of the identified electric vehicles; and

resume the charging of the one of the identified electric vehicles.

15. The system of claim 11, wherein the tracking server is further configured to unidentify one of the identified electric vehicles when a State of Charge (SOC) of the one of the identified electric vehicles is less than a minimum SOC.

16. The system of claim 11, wherein the tracking server is further configured to unidentify one of the identified electric vehicles when historical data indicates usage of the one of the identified electric vehicles is imminent.

17. The system of claim 11, wherein the tracking server is further configured to confirm charge interruption of each of the identified electric vehicles.

18. The system of claim 17, wherein the tracking server is further configured to award an incentive or credit to each of the identified electric vehicles confirming charge interruption.

19. The system of claim 17, wherein the tracking server is further configured to transmit the charge interruption signal prior to a charge interruption start time specified in the time period information.

20. The system of claim 11, wherein the tracking server is further configured to transmit a charge resumption signal after a charge interruption end time specified in the time period information.
