<p>PROBLEM TO BE SOLVED: To uniformly cool numerous storage battery modules disposed inside a case. SOLUTION: In a storage battery unit, a pressure reserving chamber 20 and an exhaust chamber 30 are superposed at the lower and upper surfaces of a case body 10 of a flat casing type, respectively, and numerous storage battery modules 12 are fixed at a bottom plate 11 of the case body 10 in vertical and lateral arrangement in a flat superposing state. Introducing openings 17 are formed in a manner corresponding to outside cooling flow paths 16 around the storage battery modules 12 at the bottom plate 11. Cooling air is allowed to flow into the outside cooling flow paths 16 from the pressure reserving chamber 20 through the introducing openings 17. Air orientation changing plates 18 are arranged in the outside cooling flow paths 16, so that the cooling air flowing vertically from the introducing openings 17 is allowed to laterally flow in inside cooling flow paths 14 of the storage battery modules 12.</p> |
