Abstract

An energy exchange network provides a coupling service to users of the network. Access to a user through an access controller is controlled initially by allowing only the coupling service to communicate with the user. Several wireless communications zones are established so that the vehicle can be identified and guided to effect coupling. The coupling service effects control of the physical connection of a user vehicle to the energy exchange network. Typically, other services are subsequently provided and a service is not given more access than needed at any point in the sequence, hence a user can only respond to the service currently connected and cannot access other services. The coupling service automates connection to the energy exchange network while protecting the network against unauthorized access. A security service is associated with the coupling service to provide various levels of security for users of the coupling service.
