Abstract

An electric vehicle charging station network server which manages a plurality of charging stations receives subscriber notification message preferences for a subscriber (e.g., electric vehicle operator) which indicate one or more events of interest that the subscriber wishes to receive notification messages for. A set of one or more contact points associated with the subscriber is also received. The server authorizes the subscriber to use one of the plurality of charging stations. The server receives data associated with the subscriber from that one of the charging stations which indicates that a charging session has been established for an electric vehicle associated with the subscriber. The server detects an event of interest for the subscriber and transmits a notification message for that event to at least one of the set of contact points associated with the subscriber.
