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.

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.
An electric vehicle, comprising:
- a motor to operate based on electrical energy;
- and
- a battery pack to supply electrical energy to the motor, wherein the battery pack includes:
- 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.
An apparatus, comprising:
- an interface;
- and
- logic to determine a moving state of a load based on inertia information from an inertia sensor and to output at least one control signal to interrupt flow of a discharge current of a battery when discharge current of the battery is equal to or greater than a first critical current value for a preset time period and the load is determined to be stationary.
