Provided is a battery pack, which has a reduced number of embedded components so as to have reduced cost and weight and has an efficiently adjusted internal temperature so as to have improved performance and stability, the battery packing including: a lower case including a first lower side wall extending from a bottom surface, and a second lower side wall and a third lower side wall respectively connected with the first lower side wall and arranged so as to face each other, wherein the side facing the first lower side wall is open; a battery unit accommodated in the lower case and including a plurality of battery cells; and an upper case arranged to face the lower case so as to seal the battery unit.

Battery pack

An embodiment of the present disclosure provides a battery pack including: a plurality of battery modules each including at least one battery cell; a housing supporting the plurality of battery modules which are arranged side by side in a first direction, the housing including a support wall that covers at least one surface of the plurality of battery modules and a barrier wall that is placed between the plurality of battery modules; a compression member provided on the housing and pressing the plurality of battery modules; and a cover coupled to the housing and covering the plurality of battery modules and the compression member.

An embodiment of the present disclosure provides a device for cooling a battery pack, the device including: a housing including flow passages extending in a first direction; a first sub-housing provided on the housing in the first direction; and a second sub-housing arranged opposite the first sub-housing in the first direction and provided on the housing, wherein the first sub-housing includes a first coupling hole communicating with one of the flow passages and a first guide hole communicating with at least one of the flow passages, the second sub-housing includes a second coupling hole communicating with one of the flow passages and a second guide hole communicating with at least one of the flow passages, and a path of a fluid flowing in the flow passages varies according to installation positions of coupling members inserted into the first and second coupling holes.

Device for cooling battery pack

A battery pack includes a housing accommodating a battery cell and having a throughhole; and a pressure equalization device coupled to the throughhole and equalizing internal and external pressures of the housing, wherein the pressure equalization device includes a first pressure equalization member configured to equalize the internal and external pressures of the housing when a variation in the internal pressure of the housing is smaller than a reference pressure variation; and a second pressure equalization member configured to equalize the internal and external pressures of the housing when the variation in the internal pressure of the housing is greater than the reference pressure variation.
