Claim 0:
1. A battery module comprising:
a battery cell assembly including a stack of a plurality of battery cells;
a module case which receives the battery cell assembly therein;
an electrical wire extending along an outer side of the battery cell assembly and positioned between the outer side of the battery cell assembly and an opposing inner surface of the module case; and
a thermally conductive adhesive interposed between the outer side of the battery cell assembly and the opposing inner surface of the module case, the thermally conductive adhesive extending over an enclosed region of the outer side of the battery cell assembly,
wherein the electrical wire extends across the enclosed region of the outer surface of the battery cell assembly so as to separate the enclosed region into a first covered subregion and a second covered subregion on respective opposing sides of the electrical wire, wherein the thermally conductive adhesive covers the first covered subregion and the second covered subregion without extending over the electrical wire, such that a noncovered subregion in which the thermally conductive adhesive is not present is defined between the first and second covered subregions, the noncovered subregion forming a narrow strip elongated along the electrical wire,
wherein the first covered subregion, the second covered subregion, and the noncovered subregion collectively define the enclosed region, and wherein the first and second covered subregions together occupy a majority of the area of the enclosed region, such that the thermally conductive adhesive is uniformly distributed over all of the plurality of battery cells of the battery cell assembly except for the narrow strip of the noncovered subregion.
