Battery Module

摘要

Provided is a battery module, wherein heat-radiating plates are coupled to a plurality of battery cells stacked and arranged in the battery module so as to be closely adhered to both surfaces of each of the battery cells, curved parts are formed on both sides of each of the heat-radiating plates, adjacent heat-radiating plates are formed to be spaced apart from each other by a predetermined distance, such that a volume change caused by expansion of the battery cell and a dimensional tolerance of the battery cell itself may be absorbed, and cooling performance may be improved.

1. A battery module comprising:
a plurality of battery cells stacked and arranged in parallel with each other so as to be spaced apart from each other by a predetermined distance; heat-radiating plates closely adhered to both surfaces of each of the battery cells and formed to protrude toward both sides of the battery cells; and supporters interposed between one pair of heat-radiating plates at both sides of each of the battery cells, respectively, wherein curved parts are formed at both sides of each of the heat-radiating plates, both ends of one pair of adjacent heat-radiating plates are closely adhered to each other, and closely adhered parts between both side curved parts are formed to be spaced part from each other by a predetermined distance.
