Abstract: A battery pack including at least one battery cell, a protective circuit module on a side of the at least one battery cell, and a case including the protective circuit module and the at least one battery cell. The protective circuit module includes a battery management system, an inverter, and an output terminal to supply power for driving a motor.

Abstract: A battery pack including a battery, a sensor, a controller, and a self-discharge circuit. The battery includes at least one battery cell connected between a pair of external terminals. The at least one battery cell is used for an engine-start attempt. The sensor detects a temperature of the battery. The controller compares the temperature of the battery with a reference temperature value and outputs a self-discharge signal when the temperature of the battery is lower than the reference temperature value. The self-discharge circuit is connected between the pair of external terminals in parallel with the battery and performs self-discharge the battery based on the self-discharge signal.

Abstract: A battery module including: a plurality of battery packs each having a plurality of battery banks; a first wire that connects the plurality of battery packs in parallel; and a second wire that connects battery banks of the different battery packs in parallel. A natural balancing operation may be implemented without a complicated circuit configuration.
