Provided is a battery pack, and more particularly, a battery pack capable of preventing degradation of performance at a low temperature by allowing a portion of air exhausted through an exhaust port to be introduced into an inhalation port to optimize a temperature of external air introduced into a cell module.

Battery pack

A battery module assembly according to one embodiment of the present invention includes: a heat pipe having a battery module in which a plurality of battery cells are stacked in one direction, a coupling part which is in contact with and coupled to the side surface part of the battery module, and a cooling part which extends from the coupling part so as to project away from the battery module; and a cooling plate, one surface of which is in contact with and coupled to the cooling part of the heat pipe. A cooling passage may be formed on the other surface of the cooling plate. According to the present invention, heat generated from the battery module including the battery cell can be cooled effectively.

Battery module assembly

Provided are a battery module and a method for manufacturing the same. The battery module includes: a plurality of battery cells spaced apart from each other by a predetermined interval and stacked in parallel with each other; a plurality of heat exchange members integrally formed by connecting parts connecting between two partition walls neighboring to each other among partition walls each slid between the battery cells, respectively; and a filler applied onto the heat exchange members.
