A battery pack includes a battery, a battery management system (BMS), a charge switch, a discharge switch, and a tilt sensor. The BMS monitors voltage and current states of the battery and control charge and discharge operations of the battery. The charge and discharge switches operate based on control signals from the BMS. The BMS measures a variation in tilt angle of the battery pack or a load based on tilt information sensed by the tilt sensor, and turns off the discharge switch when the tilt angle variation is equal to or less than a first critical value for a preset time period. The load may be an electric vehicle or another type of load.
