Abstract

Methods and apparatus are provided for charging an onboard energy storage system of a plug-in vehicle using a charging station. An embodiment of the system includes a vehicle communication system configured to transmit data related to charging authorization to the charging station. The embodiment also includes an electronic device configured to communicate with the vehicle communication system within a set range from the plug-in vehicle; and a vehicle controller communicatively coupled to the vehicle communication system. The vehicle controller is configured to direct the vehicle communication system to transmit the data related to charging authorization if the electronic device is within the set range from the plug-in vehicle.

Claims

1. A system for charging an onboard energy storage system of a plug-in vehicle using a charging station, the system comprising:

a vehicle communication system configured to transmit data related to charging authorization to the charging station;

an electronic device configured to communicate with the vehicle communication system within a set range from the plug-in vehicle; and

a vehicle controller communicatively coupled to the vehicle communication system and configured to direct the vehicle communication system to transmit the data related to charging authorization if the electronic device is within the set range from the plug-in vehicle.

2. A system according to claim 1, wherein the vehicle communication system detects whether the electronic device is within the set range and wherein the vehicle controller prevents transmission of the data related to charging authorization if the electronic device is not detected within the set range.

3. A system according to claim 1 wherein the system includes a charging station comprising:

a station communication system configured to receive the data related to charging authorization from the plug-in vehicle;

a power flow switch configured to regulate electrical power for charging the onboard energy storage system;

a database including identification data related to plug-in vehicles authorized to charge at the charging station; and

a station controller communicatively coupled to the station communication system and to the database, the station controller configured to direct the power flow switch to allow charging of the onboard energy storage system if the data related to charging authorization corresponds to the identification data in the database.

4. A system according to claim 3 further comprising a charging cable coupled to the charging station and configured to provide the electrical power for charging the onboard energy storage system.

5. A system according to claim 4 wherein the charging cable is configured to couple the station communication system to the vehicle controller.

6. A system according to claim 1 wherein the vehicle communication system includes a short range wireless transmitter for communication with the electronic device.

7. A system according to claim 1 further comprising a vehicle driver interface device coupled to the vehicle controller, wherein the vehicle communication system detects whether the electronic device is within the set range and wherein the vehicle controller prompts a vehicle driver for a password through the vehicle driver interface device, if the electronic device is not detected within the set range.

8. A charging system for charging an onboard energy storage system of a plug-in vehicle, the charging system comprises:

a station communication system configured to receive data related to charging authorization from the plug-in vehicle;

a power flow switch configured to regulate electrical power for charging the onboard energy storage system;

a database including identification data related to plug-in vehicles authorized to charge at a charging station; and

a controller communicatively coupled to the station communication system and to the database, the controller configured to direct the power flow switch to allow charging of the onboard energy storage system if the data related to charging authorization corresponds to the identification data in the database.

9. A charging system according to claim 8 wherein the station communication system is configured to establish a secure communication link with the plug-in vehicle.

10. A charging system according to claim 8 wherein the plug-in vehicle comprises:

a vehicle communication system configured to transmit data related to charging authorization to the station communication system; and

an authentication system configured to verify presence of a vehicle operator prior to transmitting of the data related to charging authorization to the station communication system.

11. A charging system according to claim 8 wherein the controller is configured to direct the power flow switch to supply a pulse of electrical power to the plug-in vehicle to activate the plug-in vehicle prior to receiving the data related to charging authorization.

12. A method of charging an onboard energy storage system for a plug-in vehicle using a charging station, the method comprising:

transmitting a signal to an electronic device; and

if a response signal is received from the electronic device, transmitting charge authorization information to the charging station.

13. A method according to claim 12 further comprising detecting a charging cable connected to the plug-in vehicle, and activating the onboard energy storage system in response to the detecting of the charging cable.

14. A method according to claim 12 wherein the transmitting of the signal to the electronic device includes encrypting the signal prior to transmitting.

15. A method according to claim 12 wherein the response signal from the electronic device includes the charge authorization information.

16. A method according to claim 12 wherein the transmitting of the charge authorization information to the charging station includes transmitting vehicle identification information.

17. A method according to claim 12 wherein the transmitting of the charge authorization information to the charging station includes transmitting financial account information.

18. A method according to claim 12 wherein the transmitting of the charge authorization information to the charging station includes transmitting authorization codes to access financial account information in a remote database.

19. A method according to claim 12 wherein the charging station includes a power flow switch configured to regulate charging of the onboard energy storage system, and a database containing identification data related to plug-in vehicles authorized to charge at the charging station, the method comprising:

receiving, from the plug-in vehicle, the charge authorization information;

if the charge authorization information corresponds to the identification data in the database, regulating the power flow switch to allow charging of the onboard energy storage system.

20. A method according to claim 12 wherein if a response signal is not received from the electronic device, prompting a vehicle driver for a password, and verifying the password prior to transmitting the charge authorization information to the charging station.
