A method of controlling a battery pack comprising a plurality of battery cells, the method comprising:
- permanently cutting off charging and discharging paths of the battery pack;
- and
- discharging one or more of the battery cells when the one or more battery cells satisfy a reference condition.
A battery pack comprising:
- a plurality of battery cells;
- a protection device for permanently cutting off charging and discharging of the battery pack;
- a discharge circuit for discharging one or more of the plurality of battery cells;
- and
- a battery management system (BMS) for operating the discharge circuit to discharge one or more of the plurality of battery cells, when the one or more of the plurality of battery cells satisfy a reference condition, after operating the protection device.
A battery pack comprising:
- a plurality of battery cells;
- a sensing device for sensing conditions of the plurality of battery cells;
- and
