A battery pack includes a battery, a battery management system (BMS), and an inertia sensor. The battery includes at least one battery cell to supply electricity to a load. The BMS monitors voltage and current states of the battery and to control charge and discharge operations of the battery. The BMS determines a moving state of the load based on inertia information from the inertia sensor and outputs a control signal to interrupt flow of a discharge current of the battery when the discharge current is equal to or greater than a first critical current value for a preset time period and the load is determined to be stationary.
