PURPOSE:To obtain a high capacity battery which can charge/discharge a high current by employing a parallel circuit of a high capacity battery which can not charge/discharge a high current and a low capacity battery or a capacitor which can charge/discharge a high current. CONSTITUTION:A high capacity battery 1 which can not charge/discharge a high current, e.g. a nickel/hydrogen battery, is connected in parallel with a low capacity battery 2 which can change/discharge a high current, e.g. a nickel/ cadmium battery. When a switch 4 is turned ON, power is fed from the batteries 1, 2 in case of a light load whereas power is fed mainly from the battery 2 through high current discharge in case of a heavy load. When the switch 4 is turned OFF, the battery 2 is charged by the batter 1. The operation is repeated. The batteries 1, 2 function as a high current, high capacity battery when it is viewed from the load 3 side. |
