BATTERY MODULE WITH IMPROVED UNIFORMITY IN TEMPERATURE OF BATTERY CELLS

A battery module includes a module case having a battery cell stack constituted by a plurality of stacked battery cells received therein, a heat dissipation resin added between the battery cell stack and a first surface of the module case, a cooling member coupled outside the first surface of the module case, the cooling member being configured to cool the battery cell stack, and a heat transfer material added to a middle part of an outer surface of the cooling member that faces the first surface of the module case. The heat transfer material is disposed at a part of the battery cell stack that has a relatively high temperature, whereby temperature deviation between the battery cells is reduced.
