Abstract

A vehicle system has a first communication device configured to selectively associate with a second communication device of a premise system based on a location of the vehicle with respect to the premise system and a vehicle identification. A charging control system is configured to permit charging of the vehicle in response to the selective association between the first and second communication devices.

Claims

1. A system comprising:

a vehicle system for use on a vehicle, the vehicle system including a first communication device being configured to selectively associate with a second communication device of a premise system remote from the vehicle based on (i) a relative location of the vehicle to the premise system and (ii) a vehicle identifier; and

a charging control system configured to permit charging of the vehicle in response to the selective association between the first and second communication devices.

2. The system of claim 1 wherein the charging control system is further configured to activate a vehicle charger to charge the vehicle in response to the selective association.

3. The system of claim 1 wherein the first communication device is further configured to present the vehicle identifier to the second communication device for authentication.

4. The system of claim 1 wherein the first communication device is further configured such that the selective association with the second communication device is exclusive.

5. The system of claim 1 wherein the first communication device is further configured to terminate the selective association with the second communication device when the vehicle travels farther than a predetermined range from the second communication device.

6. The system of claim 1 wherein the charging control system is further configured to communicate with a power grid to activate charging of the vehicle.

7. A system comprising:

a vehicle system for use on a vehicle, the vehicle system including a first communication device being configured to transmit an association request containing an authentication signal and data regarding the location of the vehicle;

a premise system for use on a customer premise, the premise system including a second communication device being configured to receive the association request and to selectively cause an association of the first and second communication devices based on the authentication signal and data regarding the location of the vehicle; and

a charging control device configured to permit charging of the vehicle in response to the association of the first and second communication devices.

8. The system of claim 7 wherein the first communication device is further configured terminate the association with the second communication device when the vehicle travels farther than a predetermined range from the second communication device.

9. The system of claim 7 wherein the charging control device is further configured to communicate with a power grid to activate a charger on the premise system.

10. The system of claim 7 wherein the first communication device is further configured such that a selective association with the second communication device is exclusive.

11. The system of claim 7 wherein the charging controller is further configured to permit coupling between the vehicle and a primary inductive charger located on the charger controller upon a selective association between the first communication device and second communication device.

12. The system of claim 7 wherein the charging controller is further configured to communicate data to and from a power grid.

13. The system of claim 7 wherein the premise system is further configured to authenticate the vehicle upon receiving the association request from the first communication device.

14. A vehicle comprising:

a vehicle system having a first communication device being configured to selectively associate with a second communication device of a premise system based on a relative location of the vehicle to the premise system and a vehicle identifier,

wherein the vehicle system is configured to, in response to the association, generate a charge control command to cause a charging control system to charge the vehicle.

15. The system of claim 14 wherein the vehicle system is further configured to send and receive communication from a power grid.

16. The system of claim 14 wherein the first communication device further communicates an association request to the second communication device.

17. The system of claim 16 wherein the association request further includes the vehicle identifier and an authentication protocol.

18. The system of claim 14 wherein the selective association between the first communication device and the second communication device terminates upon the first communication device moving a predetermined range away from the premise system.

19. The system of claim 14 wherein the first communication device is further configured to associate with exactly one second communication device.
