PROBLEM TO BE SOLVED: To cool a battery module effectively.SOLUTION: A power supply device 1 includes a battery module 7 including multiple battery cells 8, a housing body 4 having a bracket 15 constituting a first chamber 13 for housing the battery module and housing multiple battery modules in parallel, an enclosure 3 constituting an internal space surrounded by multiple wall faces, and housing the housing body 4 in the internal space, and a blower 5 provided in the enclosure and blowing air. A second chamber 70 for feeding the air, passed through the first chamber, toward the suction part 5a of the blower 5 is constituted between the wall surface and the bracket, the bracket has a partition board for partitioning the first and second chambers, and a delivery part provided in the partition board and sending out the air passed through the battery module to the second chamber, partition board is separated from the second chamber side wall surface of the enclosure so as to expand the volume of a region between the second chamber side wall surface and the partition board, and in the parallel direction of the multiple battery modules, the length of the bracket is greater than the distance between the wall surfaces constituting the second chamber inner face.SELECTED DRAWING: Figure 2

    【課題】電池モジュールを効果的に冷却すること。【解決手段】電源装置1は、複数の電池セル8を含む電池モジュール7と、電池モジュールを収容する第1室13を構成し且つ複数の電池モジュールを並列させて収容するブラケット15を有する収容体4と、複数の壁面により囲まれる内部空間を構成し、当該内部空間に収容体4を格納する筐体3と、筐体内に設けられて空気を吹き出す送風機5を備え、壁面とブラケットの間に第1室を通過後の空気を送風機の吸い込み部5aに向けて流す第2室70が構成され、ブラケットは、第1室を第2室と区画する区画板と、区画板に設けられ電池モジュールを通過した空気を第2室に送り出す送出部を有し、区画板は、第2室側の壁面と当該区画板の間の領域の容積を拡張すべく筐体の第2室側の壁面と離間し、複数の電池モジュールの並列方向において、ブラケットの長さは、第2室内面を構成する壁面間の距離より大きい。【選択図】図2
