PROBLEM TO BE SOLVED: To cool a battery cell of a battery module with high efficiency.SOLUTION: A power supply device 1 comprises: a battery module 7 including a plurality of battery cells 8; a housing body 4 that constitutes a housing chamber 13 that arranges and houses the plurality of battery modules; and an air blower 5 that blows an air. An inter-module passage 12 is constructed between the adjacent battery modules. An inter-cell passage 11 is constructed between the adjacent battery cells. The housing body includes: a fetching part 17A that fetches an air blow from the air blower; and a transmission part 16 that transmits the air fetched from the fetching part and passed through the inter-module passage and the inter-cell passage. The inter-module passage includes a first inter-module passage 12A into which the air before fetched from the fetching part and passes through the inter-cell passage is inserted. The transmission part is separated from the first inter-module passage through at least one battery module so that the air is passed in the inter-cell passage of each of the plurality of adjacent battery modules while nipping the first inter-module passage.SELECTED DRAWING: Figure 2
【課題】電池モジュールの電池セルを効率よく冷却すること。【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、複数の電池モジュールを並列させて収容する収容室13を構成する収容体4と、空気を吹き出す送風機5を備え、隣り合う電池モジュール間にモジュール間通路12が構成され、隣り合う電池セル間にセル間通路11が構成され、収容体は、送風機から吹き出された空気を収容室内に取り入れる取入部17Aと、取入部から取り入れられモジュール間通路とセル間通路を通過した空気を収容室から送り出す送出部16を有し、モジュール間通路は、取入部から取り入れられセル間通路を通過する前の空気が導入される第1モジュール間通路12Aを有し、第1モジュール間通路を挟んで隣り合う複数の電池モジュール夫々のセル間通路に空気が流通するように、送出部は少なくとも1つの電池モジュールを介して第1モジュール間通路と離間している。【選択図】図2
