Therefore, ignition of the gas exhausted from the opening 226 can be effectively prevented, and rupture of the battery module 200 can be reliably prevented.
- the partition wall 232 of the housing 230 prevents the heat of the battery unit 240, which has generated abnormally, from being transmitted to the adjacent battery unit 240. As a result, it is possible to significantly suppress the influence of the heat transfer from the storage unit 234 storing the battery unit 240 that generates heat abnormally to the battery unit 240 stored in another storage unit 234.
