  • Patent number: 8581557
    Abstract: A direct-current power source apparatus in which a lithium-ion capacitor unit is used as an electric storage system and which can fully utilize the lithium-ion capacitor unit and maintain the supply of electricity to a load is provided. An electric storage system includes a lithium-ion capacitor unit and a lead-acid battery connected in parallel with a load, and a voltage detecting section that detects the voltage of the lithium-ion capacitor unit. When the voltage detecting section detects that the voltage of the lithium-ion capacitor unit has reached a unit lower-limit voltage, a control circuit outputs a conduction signal for causing a switching circuit to get into a conductive state. When the switching circuit gets into a conductive state, the secondary battery supplies an electric power to a motor. At this time, the secondary battery charges the lithium-ion capacitor unit.

  • Patent number: 6979977
    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.
