<p>PROBLEM TO BE SOLVED: To be able to equalize sufficiently temperature of each unit cell 2, as well as to diffuse to the outside heat generated from each unit cell 2 with sufficiently high thermal conductivity, in a battery pack structured by setting together a plurality of cylindrical type unit cells 2 in a metal exterior case 1. SOLUTION: In a space pinched by an outer circumference surface of a plurality of unit cells 2 and an inner surface of an exterior case 1, a hollow fitting 3 having an outer shape appropriated with a three-dimensional shape of the space is set, a heat transfer cement 4 filled in the cavity of the hollow fitting 3.</p> |
