Abstract: As a cooling draft flows from a rear side to a front side of battery cells (72) inside a battery pack (30), it is divided into two cooling drafts (F1, F2) in a left-right direction, which is the direction that the battery cells (72) are disposed in parallel, and those two cooling drafts respectively flow through a plurality of passageways that longitudinally extend along the battery cells (72). More particularly, a second battery cell (722) is cooled by the cooling draft flowing in a second ventilation-path volume (Q2) before a first battery cell (721) and a third battery cell (723) are cooled by cooling drafts respectively flowing in a first ventilation-path volume (Q1) and a third ventilation-path volume (Q3), which are longer than the second ventilation-path volume (Q2).
Abstract translation: 当电池组30内部的电池单体72的后侧流向前侧时，在左右方向上分为两个冷却通风口（F1，F2） 电池单元（72）平行设置，并且这两个冷却通风分别流过沿着电池单元（72）纵向延伸的多个通道。 更具体地，在第一电池单元（721）和第三电池单元（723）通过分别流过的冷却风流冷却之前，通过在第二通气量（Q2）中流动的冷却通风来冷却第二电池单元（722） 在第一通风路径体积（Q1）和第三通风路径体积（Q3）中，其比第二通气道容积（Q2）长。

Abstract: A battery housing portion S includes regulating members 30 adapted to fit grooves of a battery pack having a T-shape cross section, so that the battery pack can be housed in the battery housing portion S in the state that the both regulating members 30 fit the grooves. The regulating members 30 regulate housing orientation of the battery pack 20, so that misjudgment about orientation of the battery pack 20 is prevented. In addition, if the orientation has been misjudged, an operator can notice such misjudgment immediately, thereby improving the operability during mounting the battery pack 20.
