Patent attributes
Various embodiments provide battery packs. A battery pack includes: a battery including at least one battery cell and configured to be discharged at a first discharge current or a second discharge current; and a switch connected to the battery and placed on a high current path through which charge current and discharge current of the battery flow, wherein when the discharge current of the battery is the first discharge current, discharging of the battery is stopped as voltage of the battery reaches a first discharge cut-off voltage, and when the discharge current of the battery is the second discharge current, discharging of the battery is stopped as the voltage of the battery reaches a second discharge cut-off voltage, wherein the first discharge current is greater than the second discharge current, and the first discharge cut-off voltage is greater than the second discharge cut-off voltage.
