Abstract:
1. A method for high quality of service for a networked electric vehicle charging station in an unreliable network, wherein the networked electric vehicle charging station is coupled with an electric vehicle charging station network server that performs profile based authorization during regular operation, and wherein the networked electric vehicle charging station communicates with the electric vehicle charging station network server over a communication connection, the method comprising: transmitting charging session authorization requests to the electric vehicle charging station network server while the communication connection between the networked electric vehicle charging station and the electric vehicle charging station network server is functioning correctly; receiving a local authorization list; performing a local authorization of charging session requests while the communication connection between the networked electric vehicle charging station and the electric vehicle charging station network server is not functioning correctly, wherein each of the charging session requests includes an identifier associated with an electric vehicle operator, and wherein performing the local authorization for each charging session request while the communication connection between the networked electric vehicle charging station and the electric vehicle charging station network server is not functioning correctly includes comparing the identifier associated with an electric vehicle operator included in that charging session request against the local authorization list to determine whether to grant the charging session request and initiate a charging session; storing state data for those charging sessions initiated while the communication connection between the networked electric vehicle charging station and the electric vehicle charging station network server is not functioning correctly; and transmitting the stored state data to the electric vehicle charging station network server upon determining that the communication connection is restored.
