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.

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 protection circuit is provided. The protection circuit protects a battery pack from overcurrents and overvoltages using sensing means and a protection device having a heating resistor and a fuse element provided on a circuit board. This protection circuit allows for sharing a protection device regardless of the current rating and the voltage rating of the battery pack, thereby being manufactured at low costs. A protection circuit protects a battery pack having serially connected rechargeable batteries from overcurrents and overvoltages. The protection circuit includes a protection device having heating resistors and fuse elements provided on a circuit board, and sensing means for detecting an overvoltage across any of the batteries in the battery pack and switching a current flowing into the heating resistor. The protection circuit allows the sensing means in an overvoltage condition to switch on the current flowing through the heating resistor. This allows the voltage across a predetermined number of the serially connected batteries in the battery pack to be applied to the heating resistor, thereby causing the heating resistor to generate heat and the fuse element to be melted.

摘要： A secondary battery of the present invention a heat-sensitive element which varies in resistance value due to change of temperature is not placed on a path through which a charge or discharge current flows into or out of a storage battery. Accordingly, when a main switch element generates heat due to an overcurrent, a change in resistance value of the heat-sensitive element resulting from the heat will allow an auxiliary switch to be turned ON, thereby causing first and second auxiliary fuses to be blown. The charge or discharge current causes no power consumption at the heat-sensitive element, thereby providing high efficiency. The heat-sensitive element can be reduced in current capacity for use and it is suitable for compact design.
