Overriding delayed electric vehicle charging events

摘要

An electric vehicle charging station that supports delayed charging overrides. In one embodiment, to support delayed charging override in an electric vehicle charging station that requires authorization, after authentication is successful (e.g., the electric vehicle operator is authorized) and the electric vehicle is detected (e.g., the charging cord has been plugged into the charging port of the electric vehicle), the charging station begins a plug out timer for the electric vehicle operator to unplug the charging cord from the charging port of the electric vehicle and then begins a plug-in timer for the electric vehicle operator to plug the charging cord back into the charging port of the electric vehicle. If the electric vehicle operator does so within the periods of the timers, the charging session will not end and the delayed charging will be overridden.

主权项

1. A method in an electric vehicle charging station to support delayed charging override, comprising:
receiving a request for charging service from an electric vehicle operator, wherein the request for charging service includes an identifier; determining, based at least in part on the identifier, that the electric vehicle operator is authorized to use the electric vehicle charging station; and responsive to detecting that an electric vehicle has been connected to the electric vehicle charging station, performing the following:
starting a plug-out timer,responsive to determining that the electric vehicle has been disconnected prior to the plug-out timer expiring, starting a plug-in timer, andresponsive to determining that the electric vehicle has been connected to the electric vehicle charging station prior to the plug-in timer expiring, maintaining a charging session during which charging of the electric vehicle may occur, without requiring the electric vehicle operator to re-authorize.
