Summary: | A protection apparatus for a secondary battery includes a memory unit, a measurement unit, a temperature estimation unit and a charging/discharging control unit. The memory unit stores first and second swelling conditions of temperatures and voltages of the secondary battery. The measurement unit measures temperatures and voltages of the secondary battery according to predetermined measurement periods. The temperature estimation unit estimates a temperature after a predetermined time using the temperatures measured in the measurement unit when the measured temperatures and voltages satisfy the first swelling condition. The charging/discharging control unit controls charging/discharging of the secondary battery when the estimated temperature and the measured voltage satisfy the second swelling condition. |
