Abstract

There is disclosed an electric vehicle charging station, an electric vehicle charging system, and methods of provisioning and operating an electric vehicle charging station. The electric vehicle charging station may include a power control to control the flow of power from a power grid, a controller coupled to the power controller, and a wireless communications interface operable to communicate using a short range wireless communications protocol. The controller may be configured to communicate with a remote server opportunistically via the wireless communications interface and an available personal computing/communications device external to the electric vehicle charging station.

Claims

1. An electric vehicle charging station, comprising:

a power control to control the flow of power from a power grid;

a controller coupled to the power controller; and

a wireless communications interface operable to communicate using a short range wireless communications protocol,

wherein the controller is configured to communicate with a remote server opportunistically via the wireless communications interface and an available personal computing/communications device external to the electric vehicle charging station.

2. The electric vehicle charging station of claim 1, wherein

the controller is configured to store one or more access keys received from the remote server via the wireless communications interface and an installer'"'"'s personal computing/communications device.

3. The electric vehicle charging station of claim 2, wherein

the controller is further configured to accept a charging request from a driver of an electric vehicle via the wireless communications interface and the driver'"'"'s personal computing/communications device.

4. The electric vehicle charging station of claim 3, wherein

the controller is further configured to control the power control to allow power to flow from the power grid to the electric vehicle only after receipt, from the driver'"'"'s personal computing/communications device via the wireless communications interface, of an access key that matches one of the one or more access keys stored within the electric vehicle charging station.

5. The electric vehicle charging station of claim 3, wherein

the controller is further configured to report at least one of initiation of charging the electric vehicle and completion of charging the electric vehicle to the remote server via the wireless communications interface and the driver'"'"'s personal computing/communications device.

6. An electric vehicle charging network, comprising:

one or more electric vehicle charging stations, each electric vehicle charging station configured to communicate with personal computing/communications devices via a short range wireless communications protocol; and

a server configured to communicate with personal computing/communications devices via a second wireless communication protocol different from the short range wireless communications protocol, wherein

each electric vehicle charging station communicates with the server opportunistically via an available personal computing/communications device.

7. The electric vehicle charging network of claim 6, wherein

the second wireless communications protocol is one of a wireless local area network protocol and a cellular telephone network data communications protocol.

8. A method of provisioning an electric vehicle charging station, comprising:

transferring configuration information between the electric vehicle charging station and a remote server via a personal communications/computing device external to the electric vehicle charging station, wherein

the personal communications/computing device communicates with the electric vehicle charging station via a short range wireless communications protocol, and

the personal communications/computing device communicates with the remote server using a second wireless communications protocol different from the short range wireless communications protocol.

9. The method of claim 8, wherein

the second wireless communications protocol is one of a wireless local area network protocol and a cellular telephone network data communications protocol.

10. The method of claim 8, further comprising:

downloading an application to the personal communications/computing device; and

executing the application to manage transferring configuration information between the electric vehicle charging station and the remote server.

11. The method of claim 8, wherein transferring configuration information further comprises:

transferring an electric vehicle charging station identifier from the electric vehicle charging station to the server.

12. The method of claim 8, wherein transferring configuration information further comprises:

transferring one or more access keys from the server to the electric vehicle charging station.

13. A method of operating an electric vehicle charging station, comprising:

storing one or more access keys received from a remote server via a wireless communications interface and an available personal computing/communications device external to the electric vehicle charging station.

14. The method of claim 13, wherein communications between the wireless communications interface the available personal computing/communications device use a short range wireless communications protocol.

15. The method of claim 13, further comprising:

accepting a charging request from a driver of an electric vehicle via the wireless communications interface and the driver'"'"'s personal computing/communications device.

16. The method of claim 15, further comprising:

providing electrical power to charge the electric vehicle only after receipt, from the driver'"'"'s personal computing/communications device via the wireless communications interface, of an access key that matches one of the one or more access keys stored within the electric vehicle charging station.

17. The method of claim 15, further comprising:

reporting at least one of initiation of charging the electric vehicle and completion of charging the electric vehicle to the remote server via the wireless communications interface and the driver'"'"'s personal computing/communications device.
