METHOD AND APPARATUS FOR COMMUNICATING BETWEEN AN ELECTRIC VEHICLE AND A CHARGING STATION

摘要

A method for communicating with an electric vehicle is described, including generating a first predetermined DC voltage level on a pilot conductor, recognizing the existence of an electric connection to an electric vehicle by detecting a second predetermined DC voltage level on the pilot conductor, transmitting an actuation signal on the pilot conductor, detecting a vehicle identification signal on the pilot conductor, and opening the power supply on a power conductor.
