<p>Each battery module 100 includes a holder 20 accommodating cells 10 and made of a thermal conductive material, and a rectangular solid case 30 accommodating the holder 20. The holder 20 includes containers 21, in each of which one of the cells 10 is accommodated. The case 30 has a first side surface 30a and a second side surface 30b, which are parallel to side surfaces of the containers 21 of the holder 20, and face each other. The battery pack 200 is formed by stacking the battery modules 100 in a direction that the first side surface 30a and the second side surface 30b overlap each other. Spacers 50a and 50b, each of which has a predetermined width, are provided between adjacent two of the battery modules 100, at both ends of the first and second side surfaces 30a and 30b of the case 30 in a width direction, along a direction perpendicular to the width direction. The spacers 50a and 50b form a gap 60, through which a cooling medium flows, between the first and second side surfaces 30a and 30b.</p> |
