摘要： A battery pack includes a battery cell stack formed by a plurality of stacked battery cells, a battery module housing configured to wrap the other outer surfaces of the battery cell stack excluding a first surface and a second surface, from which electrode leads protrude, a water tank configured to supply a coolant to the battery cell or the battery module housing, and a battery pack case configured to receive a plurality of battery module housings. The battery pack case includes a pack case space portion located adjacent to the first surface and a crossbeam located adjacent to the second surface, whereby, when fire breaks out in the battery cell, it is possible to rapidly and accurately prevent spread of flames of the ignited battery cell.

摘要： A battery module includes a battery cell stack constituted by a plurality of stacked pouch-shaped battery cells, a battery module housing configured to receive the battery cell stack, and a heat dissipation member coupled to a portion of the battery module housing, wherein the heat dissipation member has a through-hole formed in a heat dissipation plate disposed so as to face the battery cell stack and a sealing member is added to the through-hole, and a method of manufacturing the heat dissipation member. It is possible to effectively prevent thermal runaway of a battery cell that has caught fire while minimizing an increase in volume of the battery module.
