PURPOSE:To provide a charge accumulated power device for motive power capable of storing charges efficiently by using capacitors, and supplying power to a load. CONSTITUTION:The charge storage power device for motive power is one which supplies power to a load by storing charges in a large-capacity capacitor, and it has a large-capacity capacitor C which is connected to a load and which supplies power to the load directly, a charging circuit 2 which charges the large-capacity capacitor C, a charging power source 1 connected to the large- capacity capacitor C through the charging circuit 2, a voltage detecting circuit 3 which detects the terminal voltage of the large-capacity capacitor C, and a charging limiting circuit S1 which discriminates that the terminal voltage detected by the detecting circuit 3 is a specified value or more and limits the charging of the large-capacity capacitor C. Consequently, it becomes possible to use the large-capacity capacitor C up to a maximum voltage designed, and raise electric energy storing efficiency. |
