Methods and Apparatus for Charging Station Identification, Authentication and Energy Delivery
A charging station, an electric vehicle and a server may cooperate to determine whether the charging station and/or the electric vehicle are authentic, so that the charging station may deliver energy to the electric vehicle and the electric vehicle may receive energy from the charging station. The charging station may authenticate the electric vehicle, the electric vehicle may authenticate the charging station or both the charging station and the electric vehicle may mutually authenticate each other. The charging station and the electric vehicle may include local data for authentication without communicating with the server. Energy is not delivered or received without successful authentication.

4 . The method of claim 1 , wherein responsive to the vehicle verification notice identifying the electric vehicle as registered and the charging station verification notice identifying the charging station as registered, further establishing a wireless short-range link between the charging station and the electric vehicle.
5 . The method of claim 4 , wherein the electric vehicle transmits a financial information to the charging station via the wireless short-range link.
6 . The method of claim 5 , wherein the charging station receives the financial information from the electric vehicle via the wireless short-range link.
7 . The method of claim 6 , wherein the charging station verifies the financial information.
8 . The method of claim 1 , wherein responsive to the vehicle verification notice identifying the electric vehicle as not registered, transmitting a message to the electric vehicle that service will not be provided.
9 . The method of claim 1 , wherein responsive to the charging station verification notice identifying the charging station as not registered, presenting a message to a driver of the electric vehicle instructing the driver to not receive services from the charging station.
10 . The method of claim 1 , further comprising performed by the charging station: requesting the vehicle identifier from the electric vehicle.
11 . The method of claim 1 , further comprising performed by the electric vehicle: requesting the charging station identifier from the charging station.
12 . A method performed by a charging station and an electric vehicle for charging a battery of the electric vehicle, the method comprising:
performed by the charging station:
requesting a vehicle identifier from the electric vehicle;
receiving the vehicle identifier from the electric vehicle;
sending the vehicle identifier to a server for verification;
receiving a vehicle verification notice from the server; and
responsive to the vehicle verification notice identifying the electric vehicle as not registered, transmitting a message to the electric vehicle that service will not be provided; and
responsive to the vehicle verification notice identifying the electric vehicle as registered, providing an amount of energy to the electric vehicle for charging the battery of the electric vehicle;
performed by the electric vehicle:
requesting a charging station identifier from the charging station;
receiving the charging station identifier from the charging station;
sending the charging station identifier to the server for verification;
receiving a charging station verification notice from the server; and
responsive to the charging station verification notice identifying the charging station as not registered, presenting a message to a driver of the electric vehicle instructing the driver to not receive services from the charging station; and
responsive to the charging station verification notice identifying the charging station as registered, receiving the amount of energy from the charging station for charging the battery of the electric vehicle.
13 . The method of claim 12 , wherein at least one of sending the charging station identifier to the server and sending the vehicle identifier to the server comprises communicating with the server via a long-range link.
14 . The method of claim 12 , wherein at least one of receiving the charging station identifier from the server and receiving the vehicle identifier from the server comprises communicating with the server via a long-range link.
15 . The method of claim 12 , wherein responsive to the vehicle verification notice identifying the electric vehicle as registered and the charging station verification notice identifying the charging station as registered, further establishing a wireless short-range link between the charging station and the electric vehicle.
16 . The method of claim 15 , wherein the electric vehicle transmits a financial information to the charging station via the wireless short-range link.
17 . The method of claim 16 , wherein the charging station receives the financial information from the electric vehicle via the wireless short-range link.
18 . The method of claim 17 , wherein the charging station verifies the financial information.
19 . A method performed by a charging station and an electric vehicle for charging a battery of the electric vehicle, the method comprising:
