Abstract: A battery pack includes a battery module and a pack case. The battery module includes a plurality of cylindrical batteries each including, at one end in a specified direction, a battery exhaust valve that opens in response to an increase in internal pressure; and a battery holder including a plurality of housing parts for the one ends of the cylindrical batteries in the specified direction to be inserted. The pack case houses the battery module and internally includes an exhaust passage for gas exhausted from at least one of the plurality of cylindrical batteries to be exhausted out of the pack case. Each of the plurality of housing parts includes a lid part facing the battery exhaust valve of a corresponding cylindrical battery. The lid part includes an opening cover part that creates a larger holder opening with a greater outside diameter than the battery exhaust valve, and the opening cover part includes a ring-shaped or incomplete ring-shaped outer periphery that is defined by a weak part with less strength than a part external to the opening cover part.

Abstract: Battery pack (10) having a substantially sealed structure includes a plurality of cells (11-16) each having an opened portion provided in order to discharge an internal gas when an internal pressure rises. Non-resettable pressure switch (30, 31) that is connected to controller (50) by a signal line. The pressure switch changes irreversibly from a significant state to a non-significant state when a pressure in battery pack (10) is greater than a predetermined pressure threshold value.

Abstract: A battery module includes a partition wall to separate an upper space from a lower space, a first plate that defines the upper space together with the partition wall, and a second plate that is disposed above the first plate such that a gap is left between the first and second plates. A case has an opening that is formed to let the gap communicate with an outside of the case. The first plate has a through hole through which the upper space and the gap communicate. The battery module further includes a through path passing through the partition wall and each of the plates to let the lower space communicate with a space above the second plate. The upper space and the gap constitute an exhaust duct, while the lower space and a top space constitute a cooling duct.
