To suppress dispersion between discharge amount of air from a first exhaust part to outside of a storage space and discharge amount of air from a second exhaust part to outside of the storage space.SOLUTION: A battery device 20 comprises: a battery pack 21 which is arranged in a storage space 17; a suction part 30 which is arranged at a first lateral direction LH side relative to the battery pack 21; a first exhaust part 41 which is arranged at the first lateral direction LH side relative to the battery pack 21 to exhaust warmed air by heat exchange with the battery pack 21; and a second exhaust part 42 which is arranged at a second lateral direction RH side relative to the battery pack 21 to exhaust warmed air by heat exchange with the battery pack 21. A first exhaust passage 51 that guides air passing through the battery pack 21 into the first exhaust part 41 and a second exhaust passage 52 that guides air passing through the battery pack 21 into the second exhaust part 42 are formed in the storage space 17. The battery device 20 includes a circulation regulation part 55 which regulates circulation of air passing through the battery pack 21 into the first exhaust passage 51.SELECTED DRAWING: Figure 3 【課題】第１排気部から収容空間外への空気の排出量と、第２排気部から収容空間外への空気の排出量とのばらつきを抑えること。【解決手段】電池装置２０は、収容空間１７に配置された電池パック２１と、電池パック２１よりも第１横方向ＬＨに設けられた吸気部３０と、電池パック２１よりも第１横方向ＬＨに配置され、電池パック２１との熱交換によって暖まった空気を外部に排出する第１排気部４１と、電池パック２１よりも第２横方向ＲＨに配置され、電池パック２１との熱交換によって暖まった空気を外部に排出する第２排気部４２とを備える。収容空間１７には、電池パック２１内を通過した空気を第１排気部４１に導く第１排気通路５１と、電池パック２１内を通過した空気を第２排気部４２に導く第２排気通路５２とが形成されている。電池装置２０は、電池パック２１内を通過した空気の第１排気通路５１への流通を規制する流通規制部５５を備える。【選択図】図３
