Battery pack

Abstract

A battery pack capable of efficiently dissipating heat generated from battery cells by increasing heat exchange efficiency using coolant, and not requiring a separate driver for driving the flow of cooling water by causing the cooling water to flow in a natural, uncompelled manner. In one exemplary embodiment, the battery pack includes a plurality of battery cells, a cooling part coupled to the plurality of battery cells and including a plurality of cooling plates including a first plate having a coolant inlet opening and a coolant exhaust opening, a second plate having a coolant flow passage, and a third plate, wherein the plurality of cooling plates are sequentially arranged adjacent the plurality of battery cells, and a coolant reservoir for supplying coolant to the first plate and for receiving the coolant from the first plate.
