BATTERY PACK AND CONTROL METHOD THEREOF

This relates to a battery pack and a control method of the battery pack. An embodiment of the present invention provides a battery pack with at least one cell module connected between a plurality of pack terminals, including: at least one thermoelectric element disposed in each of the at least one cell modules; a thermoelectric element power supply circuit configured to supply a driving voltage to the at least one thermoelectric element; and a controller configured to control the thermoelectric power supply circuit to transfer a first voltage that is applied for driving the thermoelectric element from a charger as the driving voltage for the at least one thermoelectric element when a temperature of the at least one cell module is out of a first range in a charging mode. Herein, the first voltage may be different from a second voltage that is applied for charging from the charger.
