Abstract
Description
しかしながら、近年、車両には多くの電気機器が搭載され、それらの設置スペースは極めて多くの制約を受ける。
を備えた車両用バッテリユニット。
図1は、本発明の一実施形態としての車両用バッテリユニットを表す平面図である。
図2は図1の車両用バッテリユニットのA−A線断面図である。
図1及び図2において、車両用バッテリユニット1は断面にて図示のバッテリケース2に複合バッテリユニット3が収納されて構成されている。複合バッテリユニット3は、高圧バッテリ4と低圧バッテリ5とが支持体6によって相互に絶縁された状態で一体化されて、複合バッテリユニットの構成要旨である扁平型バッテリセルの積層方向に加圧して支持されるように構成されている。高圧バッテリ4は、所定の第1の仕様の複数の扁平型バッテリセルを積層して構成されている。ここに第1の仕様とは、例えば、平均電圧が数ボルトのラミネート電池である。また、全固体バッテリであり得る。全固体バッテリである場合にも、支持体6によって、扁平型バッテリセルの積層方向に加圧して支持されるため十全に機能する。低圧バッテリ5は、所定の第2の仕様の複数の扁平型バッテリセルを積層して構成されている。ここに第2の仕様とは、例えば、平均電圧が数ボルトの電池であり、第1の仕様と同仕様であり得る。車両用バッテリユニット1は、特に、HVやHEVにおける車両用バッテリユニットとして構成される。高圧バッテリ4は、主に車両走行用の電動機等を駆動するために用いられる。低圧バッテリ5は、一般的な車両の補機の電源として用いられる。
高圧バッテリ4は、複数の扁平型バッテリセル16が積層されて構成される。各扁平型バッテリセル16は図2の視座で上辺の左右両端近傍位置に正極及び負極の電極タブ(不図示)を有する。これら複数の扁平型バッテリセル16は、図1の接続導体17によって直列に接続される。
図3から図5において、図1及び図2との対応部には同一の符号附して示し、それら対応部については、図1及び図2における説明を援用する。
