1. A battery pack, comprising:
- a battery including at least one battery cell to supply electricity to a load;
a battery management system (BMS) to monitor voltage and current states of the battery and to control charge and discharge operations of the battery; and
an inertia sensor, wherein the BMS is to determine a moving state of the load based on inertia information from the inertia sensor, and is to output 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, the first critical current value indicating that the battery has an error because the discharge current of the battery has exceeded an amount of current for a stationary state of the load indicated by the inertia information, the BMS to determine that the battery has the error when the discharge current is equal to or greater than the first critical current value.

Abstract
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.
