    • 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.
    • 每个电池模块100包括容纳电池10并由导热材料制成的保持器20和容纳保持器20的矩形固体外壳30.保持器20包括容纳在容器21中的容器21,每个电池单元10中的一个被容纳。 壳体30具有平行于保持器20的容器21的侧面的第一侧面30a和第二侧面30b,并且彼此面对。 电池组200通过在第一侧表面30a和第二侧表面30b彼此重叠的方向上堆叠电池模块100而形成。 在相邻的两个电池模块100之间,在宽度方向上的壳体30的第一和第二侧表面30a和30b的两端,沿着垂直方向的方向设置有具有预定宽度的间隔件50a和50b 到宽度方向。 间隔件50a和50b在第一和第二侧表面30a和30b之间形成间隙60,冷却介质通过该间隙流动。
