Abstract

A recharging station for recharging an electric vehicle has a fixed transceiver operable with a local interface and a wide-area wireless interface, wherein the wide-area wireless interface corresponds to a cellular network provider. A user transceiver is activated by a user to send an authentication request to the recharging station via the local interface. A front-end server in a core network of the cellular network provider communicates with the recharging station and the user transceiver. The recharging station forwards the authentication request with an identification of the recharging station to the front-end server, and the front-end server creates a PIN code in response to the authentication request if the identification of the user transceiver is verified. A back-end server associated with the utility provider receives the PIN code and verifies the identification of the recharging station. The front-end server sends the PIN code to both the user transceiver and the recharging station via the wide-area wireless interface, and the PIN code is used to initiate charging.

Claims

1. A system for recharging an electric vehicle, comprising:

a recharging station having a fixed transceiver operable with a local interface and a wide-area wireless interface, wherein the wide-area wireless interface corresponds to a cellular network provider, and wherein the recharging station has a controllable output for selectably metering electrical power from a powerline of a utility provider to the electric vehicle for recharging;

a user transceiver operable with the local interface and the wide-area wireless interface, wherein the user transceiver is activated by a user when desiring to recharge the electric vehicle to send an authentication request to the recharging station via the local interface, wherein the authentication request identifies the user transceiver;

a front-end server within a core network of the cellular network provider adapted to communicate with the recharging station and the user transceiver via the wide-area wireless interface, wherein the recharging station forwards the authentication request with an identification of the recharging station to the front-end server, and wherein the front-end server creates a PIN code in response to the authentication request if the identification of the user transceiver is verified; and

a back-end server associated with the utility provider having a network interface with the front-end server for receiving the PIN code, wherein the back-end server verifies the identification of the recharging station and sends a confirmation to the front-end server;

wherein the front-end server sends the PIN code to both the user transceiver and the recharging station via the wide-area wireless interface;

wherein the user transceiver forwards the PIN code to the recharging station via the local interface; and

wherein when the recharging station compares the PIN code received from the user transceiver with the PIN code received from the front-end server, and if they match then it initiates charging of the electric vehicle.

2. The system of claim 1 wherein the recharging station monitors an amount of electrical consumption used in recharging the electric vehicle and transmits the amount to the user transceiver at the completion of charging.

3. The system of claim 1 wherein the recharging station monitors an amount of electrical consumption used in recharging the electric vehicle and transmits the amount to the front-end server and back-end server at the completion of charging.

4. The system of claim 3 wherein the cellular network provider bills the cost of the amount of electrical consumption together with a bill for service by the wide-area wireless interface.

5. The system of claim 1 wherein the user transceiver is comprised of a mobile handset.

6. The system of claim 1 wherein the user transceiver is vehicle mounted.

7. The system of claim 1 wherein the local interface is comprised of a wireless interface.

8. The system of claim 7 wherein the wireless interface is selected from the group consisting of Bluetooth and Wi-Fi.

9. The system of claim 1 wherein the wide-area wireless interface is selected from the group consisting of CDMA, TDMA, GSM, UMTS, WiMAX, and EVDO.

10. The system of claim 1 wherein the user transceiver is identified in the authentication request by at least one of an ESN, MDN, MSID, or MAC address.

11. A method of recharging an electric vehicle of a user at a recharging station having a fixed transceiver operable with a local interface and a wide-area wireless interface of a cellular network provider, wherein the recharging station receives electrical power from a utility provider, wherein the user has a user transceiver operable with the local interface and the wide-area wireless interface, wherein a core network of the cellular network provider includes a front-end server adapted to communicate with the recharging station and the user transceiver via the wide-area wireless interface, and wherein a back-end server associated with the utility provider has a network interface with the front-end server, the method comprising the steps of:

the user sending an authentication request from the user transceiver to the recharging station via the local interface when desiring to recharge the electric vehicle, wherein the authentication request identifies the user transceiver;

the recharging station forwarding the authentication request together with an identification of the recharging station to the front-end server;

the front-end server creating a PIN code in response to the authentication request if the identification of the user transceiver is verified;

the back-end server verifying the identification of the recharging station and sending a confirmation to the front-end server;

the front-end server sending the PIN code to both the user transceiver and the recharging station via the wide-area wireless interface;

the user transceiver forwarding the PIN code to the recharging station via the local interface;

the recharging station comparing the PIN code received from the user transceiver with the PIN code received from the front-end server; and

if the PIN code received from the user transceiver matches the PIN code received from the front-end server then the recharging station initiating charging of the electric vehicle.

12. The method of claim 11 further comprising the steps of:

the recharging station monitoring an amount of electrical consumption used in recharging the electric vehicle; and

transmitting the amount to the user transceiver at the completion of charging.

13. The method of claim 11 further comprising the steps of:

the recharging station monitoring an amount of electrical consumption used in recharging the electric vehicle; and

transmitting the amount to the front-end server and back-end server at the completion of charging.

14. The method of claim 13 further comprising the steps of:

consolidating the cost of the amount of electrical consumption together with costs for service by the wide-area wireless interface; and

submitting a bill for the consolidated costs from the cellular network provider to the user.

15. The method of claim 11 wherein the user transceiver is comprised of a mobile handset.

16. The method of claim 11 wherein the user transceiver is vehicle mounted.

17. The method of claim 11 wherein the local interface is comprised of a wireless interface.

18. The method of claim 17 wherein the wireless interface is selected from the group consisting of Bluetooth and Wi-Fi.

19. The method of claim 11 wherein the wide-area wireless interface is selected from the group consisting of CDMA, TDMA, GSM, UMTS, WiMAX, and EVDO.

20. The system of claim 11 wherein the user transceiver is identified in the authentication request by at least one of an ESN, MDN, MSID, or MAC address.
