ABSTRACT:
A protective circuit for a secondary battery is formed with a heater and a thermistor that are connected in parallel, and a main fuse is connected in series with the parallel circuit. In a secondary battery equipped with this protective circuit, a charging/discharging current passes through the protective circuit and is limited by the operation of the thermistor when the voltage applied during abnormal conditions is relatively low. On the other hand, the current will cause the main fuse to blow when the voltage during abnormal conditions is high.
