摘要： A secondary battery with high safety is provided. A heater and a diode are connected in series, and a thermistor is connected in parallel with thus formed series circuit. A fuse is connected in series with thus formed parallel circuit to form a protective circuit, which is attached to an accumulator to complete a secondary battery. In the case of overcharging, the accumulator generates heat so that the thermistor heats up to increase the resistance value. As a result, the current pass through the heater, which generates heat to break the fuse. In the case of short circuit, the diode is reverse-biased and no current passes through the heater so that the fuse does not break.

摘要： 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.
