図1は、本発明の一実施形態に係るバッテリ冷却構造を採用した車両1の車室6後部及び荷室3を示す斜視図である。
図1に示すように、車両1は、後部座席2の後方に荷室3を有している。荷室3の下方には、フロアパネル7が凹状に屈曲形成されることでバッテリ収納空間5が設けられており、このバッテリ収納空間5にバッテリユニット100が配置される。フロアパネル7の下方であって、バッテリ収納空間5の両脇には、1対のフロアフレーム8が車両1の前後方向に延びている。荷室3は、バッテリユニット100を覆う後部フロア3a(図9参照)及びサイドトリム4の延出部4a(図9参照)によってバッテリ収納空間5を含む荷室下空間10から区画される。図1中の符号9は、荷室3のフロア面である。
図2は、バッテリユニット100の分解斜視図であり、図3は、バッテリフレーム14の分解斜視図であり、図4は、バッテリモジュール11及びダクト類を示す斜視図である。
図2~図4に示すように、本実施形態のバッテリユニット100は、複数のバッテリ11aを有するバッテリモジュール11と、DC-DCコンバータ12と、バッテリモジュール11及びDC-DCコンバータ12を保持するバッテリフレーム14と、これらを収容するケース15と、ケース15の上部開口を覆うカバー16と、バッテリモジュール11及びDC-DCコンバータ12を冷却するバッテリ冷却手段としての冷却機構18と、を備えており、図1に示すように、ケース15から左右に突出するバッテリフレーム14の固定部14aをフロアパネル7を介してフロアフレーム8に固定することにより、バッテリモジュール11がバッテリ収納空間5に配置されるとともにバッテリユニット100が、荷室下空間10に配置される。なお、後述する冷却機構18の上流側吸気ダクト118は、右側のサイドトリム4内を通って、後部座席2の下方に延びている。
図2に示すように、バッテリモジュール11は、矩形状であり、その長手方向が左右方向(車幅方向)に沿うようにバッテリユニット100内に配置される。各バッテリモジュール11内には、縦置きされる複数のバッテリ11aが左右方向に並べて配置されている。ここで、縦置きとは、三辺のうち最短の辺が左右方向に延びることを意味している。また、隣り合うバッテリ11a間には、後述する冷却風の流路である冷却流路11bが前後方向に沿って形成されている。冷却流路11bは、前側及び後側が開口しており、上側及び下側は気密に塞がれている。

例えば、上記実施形態では、排気口136が後部座席2の前端側下方の車幅方向左端側に配置される一方、吸気口137が後部座席2の前端側下方の車幅方向右端側に配置されていたが、逆でもよく、また、吸気口137及び排気口136は、車室6からの吸気と車室6への排気が正常に行える限り、任意の場所に設定することができる。
また、サイドトリム4に設けられるスリット4bの代わりに、シートベルト用の開口を用いて荷室3への排気を行ってもよく、サイドトリム4に別途排気口を設けてもよい。
