Abstract
Description
図1に示すように、蓄電装置1は、車両の後席のシートクッション下面と車体フロアとの間に配置される。蓄電装置1は、電気自動車の走行駆動源であるモータ・ジェネレータに給電する。蓄電装置1は、複数のバッテリモジュール2と温調装置3とで構成される。複数のバッテリモジュール2は電力を蓄電する。温調装置3は、複数のバッテリモジュール2の底面に熱的に接触する冷却部材4により、複数のバッテリモジュール2の温度を調整する。なお、バッテリモジュール2の底面と冷却部材4との間に伝熱部材を設けて、冷却効率を高めるようにしても良い。
応する第1プレート22の各位置には、下方へ突出する円筒状の突起33がバーリング加工により形成される。第1プレート22と第2プレート23とは、各突起33を各貫通孔32に挿入し、次いで各突起33を内側から拡径させて、突起33を貫通孔32にハトメのようにカシメることにより、一体化される。このように、第1プレート22及び第2プレート23の中央領域を互いに結合することにより、冷却部材4の内部空間に流通する冷却媒体の圧力が上昇した場合であっても、冷却部材4の膨らみを抑制することができる。
図14は第2実施形態にかかる温調装置を備える蓄電装置1を分解して示す図である。図15は第2実施形態にかかる温調装置を備える蓄電装置1を車体メンバに取付けた状態で示す図である。図16は図15のY矢視図である。本実施形態においては、温調装置3をバッテリケース10の下方に配置した。なお、第1実施形態の構成と同一又は対応する構成には同一符号を付してその説明を省略ないし簡略化する。
