    • Provided is a stabilization apparatus of a secondary battery, which automatically terminates an electric charging at the full-charge or over-charge point, and thus protects a lithium ion secondary battery from overcharge. The stabilization apparatus of a secondary battery comprises: a secondary battery(102); a power source(100) that is connected to both ends of the secondary battery(102) and supplies charge voltage and charge current to charge the secondary battery(102); and a secondary battery stabilization part(104) that short-circuits the power source(100) to terminate charging of the secondary battery(102) when the charge voltage of the secondary battery(102) is higher than predetermined voltage.
    • 本发明提供一种二次电池的稳定装置,其在全充电或过充电点自动终止充电,从而保护锂离子二次电池免于过充电。 二次电池的稳定装置包括:二次电池(102); 电源(100),连接到二次电池(102)的两端,并提供充电电压和充电电流以对二次电池(102)充电; 以及当二次电池(102)的充电电压高于预定电压时使电源(100)短路以终止二次电池(102)的充电的二次电池稳定部分(104)。

    • Provided is an apparatus for protecting a secondary battery, which discharges a secondary battery to protect a lithium secondary battery and a user from a risk such as firing or explosion when the battery is exposed to a calorific or high-temperature environment. The apparatus(102) for protecting a secondary battery comprises: a temperature sensor(104) that senses a temperature of a secondary battery(100) and generates control currents according to the sensed temperature; and a switching device(106) that connects both ends of the secondary battery(100) with each other to forcibly discharge the secondary battery(100) according to the control current. If the sensed temperature is above a certain temperature, the control current is supplied to the switching device(106).
