Abstract
A power controller for a vehicle controls the supply of power to an electrical load when the vehicle's engine is stopped or a key switch is turned off, so as to prevent lowering of the remaining capacity of a main battery. The control system has a control portion which controls operation of a power generator and an electrical load mounted on an automotive vehicle. The control system also includes remaining capacity measuring means for measuring the remaining capacity of a battery. The control portion drives a predetermined power load when the engine is stopped or when a key switch is held OFF, and operation of the power load is stopped when a remaining capacity of the battery measured by the remaining capacity measuring means becomes smaller than a predetermined value.
