AUTHORIZATION IN A NETWORKED ELECTRIC VEHICLE CHARGING SYSTEM
First Claim
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; and
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.

Abstract
Networked electric vehicle charging stations for charging electric vehicles are coupled with an electric vehicle charging station network server that performs authorization for charging session requests while the communication connection between the charging stations and the server are operating correctly. When the communication connection is not operating correctly, the networked electric vehicle charging stations enter into a local authorization mode to perform a local authorization process for incoming charging session requests.

6. 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, the method comprising:
-
receiving a first charging session request that includes a first identifier to request a charging session between a first electric vehicle and the networked electric vehicle charging station; performing a restricted list authorization procedure for the first identifier received in the first charging session request, wherein the restricted list authorization determines whether the first identifier belongs to a group of identifiers that can use the charging station at a time when the first charging session request is received, and wherein a result of the restricted list authorization procedure indicates that the first identifier passes the restricted list authorization procedure; generating and transmitting a first charging session authorization request to the electric vehicle charging station network server to perform a profile based authorization process for the first identifier, wherein the first charging session authorization request includes the first identifier; receiving a charging session authorization reply from the electric vehicle charging station network server that indicates whether to grant or deny the first charging session request; and granting or denying the first charging session authorization request as indicated by the received charging session authorization reply. - View Dependent Claims (7, 8, 9)

10. A networked electric vehicle charging station for charging electric vehicles, comprising:
-
a charging point connection to couple electric vehicles to a power line coupled with a power grid; an electricity control device coupled with the charging point connection to control the flow of electricity to the charging point connection; a transceiver to communicate directly or indirectly with an electric vehicle charging station network server; a charging station controller coupled with the electricity control device, the current measuring device, the transceiver, and the configuration/operator data store, the charging station controller to perform the following; receive charging session requests each including an identifier; for those charging session requests that are received while the communication connection between the networked electric vehicle charging station and the electric vehicle charging station network server is operating correctly, performing the following for each of those charging session requests; generate a charging session authorization request that includes the identifier included in that charging session request, transmit the charging session authorization request to the electric vehicle charging station network server for profile based authorization, and receive a charging session authorization reply from the electric vehicle charging station network server that indicates whether to grant or deny that charging session request, wherein the controller is to cause the electricity control device to energize the charging point connection responsive to receipt of a charging session authorization reply that indicates a granting of that charging session request; for those charging session requests that are received while the communication connection between the networked electric vehicle charging station and the electric vehicle charging station network server is not operating correctly, performing the following for each of those charging session requests; perform a local authorization procedure for that charging session request based on the identifier included in that charging session request; for those charging session requests that pass the local authorization procedure, cause the electricity control device to energize the charging point connection; and for those charging session request that fail the local authorization procedure, reject the charging session request. - View Dependent Claims (11, 12, 13, 14)
