PROBLEM TO BE SOLVED: To cool a plurality of batteries.SOLUTION: A cooling structure for vehicular battery is characterized in that a plurality of battery boxes 11 which accommodate batteries and each have an air suction port 11a for sucking cooling air and an air exhaust port 11b for discharging hot air 22 after cooling are mounted on a roof panel 10a of a vehicle 10, and a battery cover 13 which covers the plurality of battery boxes 11 is provided for the roof panel 10a. A partition 16 is provided which partitions a space surrounded with the roof panel 10a and battery cover 13 and accommodating the plurality of battery boxes 11 into air suction chambers 17 on both width-directional sides of the vehicle 10 and an air exhaust chamber 18 sandwiched between the air suction chambers 17 and extending to the front and rear. The plurality of battery boxes 11 are arrayed in two columns separately in the width direction of the vehicle 10 so as to have air suction ports 11a opened to the air suction chambers 17 and air exhaust ports 11b opened to the air exhaust chamber 18. Suction and exhaust ports 13g which communicate with the air exhaust chamber 18 are formed in the front and rear of the battery cover 13.

    【課題】複数のバッテリを均一に冷却する。【解決手段】車両用バッテリの冷却構造は、バッテリを収容して冷却風を吸引する吸気口11aと、冷却済み熱風22を排出する排気口11bとを有する複数のバッテリボックス11が車両10のルーフパネル10aに搭載され、複数のバッテリボックス11を覆うバッテリカバー13がルーフパネル10aに設けられる。ルーフパネル10aとバッテリカバー13とにより囲まれて複数のバッテリボックス11を収容する空間を車両10の幅方向の両側における吸気室17と吸気室17に挟まれて前後に延びる排気室18とに仕切る仕切り16が設けられ、複数のバッテリボックス11が吸気口11aを吸気室17に開口し排気口11bを排気室18に開口するように車両10の幅方向に分けて2列に配列される。バッテリカバー13の前後に排気室18に連通する吸排気口13gが形成される。【選択図】 図1
