  "textContent": "A protective circuit capable of coping with broad voltage variations of a battery unit to interrupt its charging/ discharging current path as damages to the heating unit are prevented from occurrence is disclosed. The protective circuit includes fuses (31a),(31b),connected to a charging/ discharging current path in series between a battery unit (10) and a charging/ discharging control circuit (20), and a heating unit (32) composed by a series connection of resistors (32a), (32b). One of two ends of the resistor (32a) or (32b) which is not connected to the peer resistor is connected to a current path of the fuses (31a), (31b). The ends of the resistors (32a), (32b) not connected to the fuses (31a), (31b), are provided with a plurality of terminals 33(a), 33(b) selected for connection to a current control element (50) that controls the current flowing through the heating unit (32), as a range of voltage variations of the battery unit (10) is taken into account.",
