Inventor: NAKAZAWA RYOJI
IPC: H01M10/44
Filed: 1993-02-08
Abstract: PURPOSE:To reduce voltage drop between a battery cell and load equipment to prevent inputting overvoltage, by detecting the voltage of the outside output terminal of a battery pack, and outputting an overvoltage signal when the voltage exceeds allowable voltage so as to interrupt a cable way. CONSTITUTION:When load equipment 20 is connected to outside output terminals 21 and 22, a transistor 50 maintains a nonconductive condition to apply no voltage to a coil 41, and a contact 42 is left to be closed to drive the equipment 20. In this case, the voltage drop in the contact 42 is slight. When a charger is connected instead of the equipment 20 and overvoltage, exceeding the allowable voltage of a battery cell 10, is applied to the terminals 21 and 22, this is detected by the voltage detector 20 to output an overvoltage signal, and the transistor 50 is made conductive to operate a relay 41 to interrupt a cable way 13 by using the contact 42. Consequently, voltage drop, between a battery cell and load equipment, is reduced to prevent the battery cell from applying of overvoltage.
