ABSTRACT:
Connection between internal batteries and external terminals of the battery pack is controlled by semiconductor switching devices, rather than by switches with mechanical contacts. When the battery pack Is not connected, battery short circuits are prevented by non-conduction of the switching devices. When the battery pack is attached to electrical equipment, a control circuit turns the switching devices on to supply power to the equipment. If the electrical equipment is a battery charger, the switching devices are turned on to supply power to the battery pack.
