Self-identifying power source for use in recharging vehicles equipped with electrically powered propulsion systems

A system for controllably providing power to recharge vehicles which include a propulsion system powered, at least in part, by electric power, at least some of which is stored onboard the vehicle in an electric power storage apparatus, comprising:

• electric grid interconnect means connected to a source of electric power for providing electric power to an electric power storage apparatus which is located in a vehicle and which is connected to said electric grid interconnect means via a conductive path which enables a flow of electric power from said source of electric power to said electric power storage apparatus;
• and
• power source identification means which transmits power source identification data, which uniquely identifies said electric grid interconnect means, to said vehicle when said vehicle is connected to said electric grid interconnect means.
