  • Publication number: 20150270590
    Abstract: Battery module includes a plurality of substantially columnar batteries, and a plurality of cases that store respective batteries and are disposed in parallel with each other. Cases are disposed so that a vent disposed in one case of two adjacent cases communicates with a vent disposed in other case. Thus, the route from another vent disposed in one case to another vent disposed in other case is formed as an airflow path passing through the vents communicating with each other between adjacent cases.

  • Publication number: 20140193674
    Abstract: A battery module includes: battery blocks which are connected to each other and each of which includes cells. Each of the cells has an opening through which a gas generated in the cell is released to an outside. Each of the battery blocks has a holder in which the cells are accommodated with the openings of the cells being aligned on a same side. On a side of the battery block on which the openings are aligned, a flat plate in touch with one end of the cells is disposed such that the gas passes above the flat plate. Each adjacent two of the battery blocks are disposed such that the flat plates are substantially flush with each other. The flat plate of one of the each adjacent two of the battery blocks extends above the holder of the other of the each adjacent two of the battery blocks.
