を有する、車両用熱マネージメントシステム。
(2) 前記制御装置は、前記低電圧系空調機器の出力に応じて前記高電圧系空調機器の出力を変える、(1)記載の車両用熱マネージメントシステム。
(3) 前記制御装置は、前記低電圧系空調機器の出力を上げたとき、前記低電圧系空調機器の出力が上げられていないときに比べて、前記高電圧系空調機器の出力を下げる、(2)記載の車両用熱マネージメントシステム。
(4) 前記メインバッテリは、モータジェネレータと電力の授受を行うことが可能とされており、
前記メインバッテリと前記モータジェネレータとの間の電力経路と前記補機バッテリとの間には、前記電力経路からの電圧を降圧するDCDCコンバータが設けられており、
前記制御装置は、前記回生電力が余剰となるときに、前記メインバッテリに充電可能な電力に対して前記回生電力が余剰とならないときに比べて、前記DCDCコンバータの電圧を上げて前記補機バッテリの電圧を上げることで、前記低電圧系空調機器の出力を上げる、(1)~(3)のいずれか1つに記載の車両用熱マネージメントシステム。
(A)制御装置16が、メインバッテリ22に充電可能な電力に対して回生電力が余剰となるときに、メインバッテリ22に充電可能な電力に対して回生電力が余剰とならないときに比べて、回生電力を供給して低電圧系空調機器14の出力を上げるため、車室乗員の快適性を維持するために必要とされる高電圧系空調機器の出力(単位時間当たりの仕事量、電力)を下げることができる。よって、車室乗員の快適性を維持しつつ電費向上を図ることができる。
