Each battery block comprises a plurality of batteries (100) that are connected in parallel, and each battery is provided with an open part (8a) for discharging a gas that is generated within the battery. Each battery block comprises: a holder (20) that houses the plurality of batteries in such an arrangement that the opening parts thereof have the same orientation; a bus bar (22) that is arranged on the holder and connects the open part-side electrodes of the batteries in parallel; and a cover (25) that is arranged on the bus bar and defines, together with the bus bar, an exhaust chamber (30) which discharges the gas discharged from the open parts to the outside of the battery block. The covers of at least two battery blocks are physically connected with each other. The covers are configured from aluminum, and the bus bars are configured from copper.</p> |
