Abstract
An apparatus including a control unit operably coupled to a voltage measuring unit, a temperature measuring unit and a discharging switch. The control unit measures a cell voltage and a cell temperature by using the voltage measuring unit and the temperature measuring unit, turns on the discharging switch to forcibly discharge the secondary battery through a load resistor when it is determined that a state where the cell voltage and the cell temperature are respectively equal to or greater than a critical voltage and a critical temperature according to a preset swelling management condition continues over a reference time, and turns off the discharging switch when a cell voltage or a cell temperature measured during the forced discharge falls below a preset safe voltage or a preset safe temperature according to the swelling management condition.
