摘要：
将沿着上下方向层叠多个单元电池(13)而成的电池(11)收纳在壳体(7)内而构成电池模块(1)，将多个电池模块(1)沿着上下方向层叠而形成电池模块层叠体(31)。壳体(7)具有下壳体(3)和上壳体(5)。下壳体(3)的侧壁部(3b)位于比上壳体(5)的侧壁部(5b)靠外侧的位置，并且侧壁部(3b)的上端(3b1)位于比侧壁部(5b)的下端(5b1)靠上方的位置。在下壳体(3)的侧壁部(3b)和上壳体(5)的侧壁部(5b)之间形成有连通部(15)，该连通部(15)将在壳体(7)的内部产生的高温气体释放到外部。
摘要（英）：

A battery module (1) is configured by housing a battery (11), which is obtained by stacking a plurality of unit cells (13) in the vertical direction, in a case (7). A battery module laminate (31) is obtained by stacking a plurality of battery modules (1) in the vertical direction. The case (7) is provided with a lower case (3) and an upper case (5). A side wall portion (3b) of the lower case (3) is positioned outside a side wall portion (5b) of the upper case (5), and the upper end (3b1) of the side wall portion (3b) is positioned above the lower end (5b1) of the side wall portion (5b). A communicating portion (15) for discharging a high-temperature gas generated within the case (7) to the outside is formed between the side wall portion (3b) of the lower case (3) and the side wall portion (5b) of the upper case (5).
