Secondary battery module and secondary battery module apparatus

A secondary battery module apparatus comprising:

• a plurality of secondary battery modules stacked in a vertical direction, each of the plurality of secondary battery modules comprising:
• a casing in which a plurality of vents are formed so as to allow outside air to flow in a vertical direction;
• at least one partition wall configured to partition an internal space of the casing into a plurality of cell chambers;
• and
• a plurality of rod-shaped battery cells housed in the cell chambers, wherein the partition wall comprises:
• a communication path configured to communicate between the cell chambers and the outside of the casing so as to allow outside air to be introduced into the internal space of the cell chambers;
• a support member configured to support the plurality of battery cells along a horizontal direction and at predetermined intervals in the vertical direction in the cell chambers such that a cell axis direction is perpendicular to the vertical direction and extends along the partition wall, wherein
• the communication path of at least one of the secondary battery modules, other than a lowermost stage secondary battery module, is connected to a pipe configured to supply air by means of an air supplying unit.

A secondary battery module comprising:

• a casing configured to house a plurality of battery cells;
• at least a first cell chamber and a second cell chamber partitioned by a partition plate within the casing, each extending in the vertical direction so as to accommodate the plurality of battery cells in a plurality of stages along the vertical direction;
• upper-side vents and lower-side vents provided to the casing and configured to allow outside air to flow through the first and second cell chambers in the vertical direction;
• and
• an outside air introduction path configured to introduce outside air acquired via outside air acquisition openings other than the lower-side vents into an intermediate stage on an outside air flow path via which outside air flows through the first and second cell chambers from the lower-side vents to the upper-side vents.
