AbstractAn electric vehicle having a computer for controlling the charging of its battery includes a probe adapted to connect with a receptacle on a charging station which has a computer for controlling the charging voltage provided over the connection to the vehicle. In response to the vehicle announcing its presence with a broadcast signal, the charge station receptacle may be raised until it senses a laser signal presented by the vehicle to indicate alignment of the receptacle with the vehicle probe. The vehicle and station communicate over a current loop to establish battery type and voltage, method of payment and credit card number, as well as the cost basis for the power. When communications are complete, the system switches over to utilize the same connections for the charging current. The computers include stop modes which they rest in, and to which they return if performance of vehicle and station diagnostics (respectively) indicate inoperability or if other faults occur. The vehicle charges the battery in a short program triggered by a AC voltage zero crossing interrupt, the background program of which determines when charging should cease because the battery is full, a switch has been operated, or because excessive voltage or current has been sensed. The charged voltage is adjusted by motor driven autotransfer in response to a computer servoprogram. Many probe, receptacle and operational details assure safe, easy, automated operation.
