Abstract
【解決手段】低圧蓄電装置22を充電する降圧器であるDC/DCコンバータ24の出力電流Idcを検出し、検出した出力電流IdcとDC/DCコンバータ24の効率ηとに基づいて、DC/DCコンバータ24の効率ηが所定効率ηth以上になるように低圧蓄電装置22に並列に接続される補機負荷20の消費電力を制御することにより、高圧蓄電装置14又は外部電源70から低圧蓄電装置22を高効率に充電することができる。

なお、上述したステップS2の判定において、DC/DCコンバータ24が作動中ではない(非作動中の)場合には(ステップS2:NO)、ステップS11にて、低圧蓄電装置22の温度Tbを温度センサ56で検出し、ステップS12にて、ステップS7〜S9の処理で説明したように、検出した温度Tb及びステップS1で検出した充電状態SOCに基づき、DC/DCコンバータ24の出力電圧、すなわち低圧蓄電装置22の電圧Vb、この場合、充電電圧Vchgを設定して(Vb=Vchg)、DC/DCコンバータ24を起動する(ステップS13)。以下、ステップS3以降の充電処理等を実行する。
14…高圧蓄電装置 18…一般負荷
20…補機負荷 24…DC/DCコンバータ
26、52、54…電流センサ 30、46…ECU
50…充電装置 56…温度センサ
70…外部電源
