In operating a battery powered vehicle, a battery charger is located at a stationary location but the battery charger control circuit is mounted on the vehicle and powered from the DC battery of the vehicle. During a charging operation, a microprocessor within the battery charger control circuit detects that a charging operation is taking place and locks the vehicle in position and when the battery charger is disconnected, the battery charger is de-energized prior to disconnecting the electrical contact between it and the vehicle to avoid arcing. The microprocessor and its memory within the battery charger control circuit records information about the energy state of the battery and controls the battery both by measuring input and output power to the battery and by measuring the rate of change of charging current. It also controls operations such as trouble lights within the vehicle and may control a speed control circuit within the vehicle as well.
