PROBLEM TO BE SOLVED: To improve energy efficiency of an entire electric power supply system in a vehicle including a converter connected between a main battery and an auxiliary machine battery.SOLUTION: In a hybrid vehicle 1, a memory 500 stores a map indicating a voltage ratio between a main battery 100 and an auxiliary machine battery 200 and a relationship between electric currents of the main battery 100 and an auxiliary machine 400 and an electric current of the auxiliary machine battery 200 when efficiency of an electric power supply system 10 becomes maximum. An ECU 600 controls a DC-DC converter 300 so that an electric current of the auxiliary machine battery 200 becomes a value calculated from outputs of electric current sensors 110, 410, outputs of voltage sensors 120, 220 and the map.SELECTED DRAWING: Figure 1

【課題】メインバッテリと補機バッテリとの間に接続されたコンバータを備える車両において、電源システム全体のエネルギー効率を改善する。【解決手段】ハイブリッド車両１において、メモリ５００は、電源システム１０の効率が最大となる場合の、メインバッテリ１００及び補機バッテリ２００の電圧比と、メインバッテリ１００及び補機４００の電流と、補機バッテリ２００の電流との関係を示すマップを記憶する。そして、ＥＣＵ６００は、補機バッテリ２００の電流が、電流センサ１１０，４１０の出力、電圧センサ１２０，２２０の出力、及びマップから求められる値になるようにＤＣＤＣコンバータ３００を制御する。【選択図】図１
