Abstract

A battery cell stack includes a plurality of battery cells, a temperature adjuster configured to prevent an increase in temperature of the battery cell stack due to a high external temperature, a heat plate disposed at a lower surface and a side surface of the battery cell stack, a pack case configured to receive the battery cell stack, the temperature adjuster, and the heat plate therein, and a cooling fan configured to discharge heat in the pack case to the outside. The battery cell stack is configured such that, when external power is supplied to an electrical apparatus connected to the battery pack, the battery cell stack does not supply current to the electrical apparatus, and when no external power is supplied to the electrical apparatus, the battery cell stack supplies current to the electrical apparatus.
