Abstract: The case housing a plurality of cells is divided, by a circuit board provided at the same sides of the cells, into a housing space housing the cells and an exhaust duct for releasing a gas from the vents of the cells to outside the case. The vents of the cells communicate with the exhaust duct through openings formed in the flat plate. The exhaust duct is divided into a first space and a second space by a partition provided between the flat plate and an external plate of the case. The first space communicates with the second space through holes formed in the partition.

Abstract: Disclosed herein is a battery pack which includes a plurality of battery modules housed in a housing. The battery modules are connected in series to each other via connecting members that connects external terminals of the battery modules to each other. The battery modules are classified into groups, each being comprised of at least two of the battery modules, two terminal ones of which have a potential difference of at most V or less between themselves. A first connecting member connects the external terminals of the battery modules to each other between two adjacent ones of the groups. A second connecting member connects the external terminals of the battery modules to each other within an identical one of the groups. If water penetrates into the housing, the first connecting member is electrically cut off, preferentially relative to the second connecting member.

Abstract translation: 这里公开了一种电池组，其包括容纳在壳体中的多个电池模块。 电池模块通过将电池模块的外部端子彼此连接的连接构件彼此串联连接。 电池模块被分成组，每个组由至少两个电池模块组成，其中两个终端电池之间的电位差最多为V或更小。 第一连接构件将两个相邻组之间的电池模块的外部端子彼此连接。 第二连接构件将电池模块的外部端子在相同的组内相互连接。 如果水渗透到壳体中，则优选地相对于第二连接构件电绝缘第一连接构件。
