PROBLEM TO BE SOLVED: To smoothly introduce air blown from a blower into a battery module.SOLUTION: A power supply device 1 includes: a battery module 7 including a plurality of battery cells 8; an accommodation body 4 constituting an accommodation chamber 13 for accommodating the battery module; a blower 5 disposed on one side of the battery module; and a housing 3 for storing the accommodation body in an internal space which is constituted by a plurality of wall surfaces including a first wall surface 31 located opposite to the one side of the battery module, a second wall surface 32 extending from the first wall surface to the blower side, and a third wall surface 33 located on the one side of the battery module. Air to be introduced into the accommodation chamber is introduced between the first wall surface and the battery module and an air introduction passage 50 having a higher pressure than the accommodation chamber is formed. A suction portion 5b of the blower is disposed between the third wall surface and the battery module, and a suction chamber 70 having a lower pressure than the accommodation chamber is formed. A communication path 65 is formed between the second wall surface and the battery module to connect a blower blowout portion 5a and the air introduction passage through the outside of the accommodation chamber.SELECTED DRAWING: Figure 2

    【課題】送風機から吹き出された空気を円滑に電池モジュールに導入すること。【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収容室13を構成する収容体4と、電池モジュールの一方側に配置された送風機5と、電池モジュールの一方側と反対側にある第1壁面31と、第1壁面から送風機側へ延びる第2壁面32と、電池モジュールの一方側にある第3壁面33を含む複数の壁面により構成した内部空間に収容体を格納する筐体3とを備え、第1壁面と電池モジュールの間に、収容室に取り入れられる空気が導入され且つ収容室より高圧の空気導入通路50が構成され、第3壁面と電池モジュールの間に、送風機の吸い込み部5bが配置され且つ収容室より低圧の吸い込み室70が構成され、第2壁面と電池モジュールの間に、送風機の吹き出し部5aと空気導入通路とを収容室の外側を通って繋ぐ連通路65が構成されている。【選択図】図2
