Abstract

A vehicle charging station for use with a system for transmitting charging power to an electric vehicle is configured to receive a unique identifier from the electric vehicle and determine a preferred electrical charging power provider based on the identifier. Vehicle charging station is further configured to determine an account associated with the preferred provider and with the identifier, deliver a quantity of electrical charging power to the electric vehicle, and meter the quantity of electrical charging power delivered to the electric vehicle.

Claims

1. A vehicle charging station for use with a system for transmitting charging power to an electric vehicle, said vehicle charging station configured to:

communicatively couple to the electric vehicle;

electrically couple to the electric vehicle via a connector;

receive a unique identifier from the electric vehicle;

determine a preferred electrical charging power provider based on the identifier;

determine an account associated with the preferred provider and with the identifier;

deliver a quantity of electrical charging power to the electric vehicle via the connector; and

meter the quantity of electrical charging power delivered to the electric vehicle.

2. A vehicle charging station in accordance with claim 1, wherein said vehicle charging station is further configured to transmit the identifier to a server to determine the preferred provider and the account associated with the identifier.

3. A vehicle charging station in accordance with claim 2, wherein said vehicle charging station is further configured to:

determine a present balance of the account based on the identifier; and

deny access to electrical charging power if the present balance of the account is less than a predetermined balance.

22. A vehicle charging station in accordance with claim 1, wherein said vehicle charging station is further configured to transmit, to the preferred provider, the quantity of electrical charging power delivered to the electric vehicle to determine a transaction amount.

23. A vehicle charging station in accordance with claim 22, wherein said vehicle charging station is further configured to deduct the transaction amount from the account.

24. A vehicle charging station in accordance with claim 1, wherein said vehicle charging station is further configured to compare the metered quantity of electrical charging power delivered with a metered value determined by the electric vehicle.

25. A vehicle charging station in accordance with claim 1, wherein said vehicle charging station is coupled to at least one visual display, said vehicle charging station is further configured to output to the at least one display at least one of a quantity of electrical charging power delivered, a monetary value of the quantity of electrical charging power delivered, and a quantity of electrical charging power remaining to be delivered.

5-21. -21. (canceled)

26. A vehicle charging system for use in charging an electric vehicle, said system comprising:
