Abstract
A method for brand identification of an electric vehicle to a charging station includes connecting a plug of the charging station to a socket of the electric vehicle, receiving a control pilot signal at the socket from the charging station, terminating the control pilot signal in a variable resistance in the electric vehicle, and toggling the variable resistance in a vehicle pattern that transitions between two charging state resistances. The charging station detects the vehicle pattern and maps the vehicle pattern to a vehicle brand of the electric vehicle. The method includes receiving electrical current to recharge the electric vehicle at the socket.
