Description
電源回路は、第1電力線と、降圧回路と、第2電力線とを備える。第1電力線は、直流インレットとバッテリとを接続する。降圧回路は、第1電力線上に配置され、直流インレットからバッテリに供給される電圧を降下させる。第2電力線の一端は、降圧回路とバッテリとの間において第1電力線に接続され、その他端は、補機部品に接続される。
電動車両は、電動車両を駆動する電動機と、電動機を駆動する電力制御ユニットとをさらに含む。降圧回路は、バッテリから供給された電圧を上昇させる昇圧機能をも有する昇降圧回路である。電源回路は、バッテリと電力制御ユニットとを接続する第3電力線をさらに備える。第3電力線は、直流インレットと昇降圧回路との間において第1電力線から分岐している。
図1及び図2を参照して、本発明の実施の形態1について説明する。
図1は、実施の形態1に係る電動車両10が備える電源回路30の構成を概略的に示すブロック図である。電動車両(以下、単に「車両」と称する)10は、モータジェネレータ(MG)12と、電力制御ユニット(PCU)14とを備えている。MG12は、一例として交流型であり、車両10を駆動するように構成されている。PCU14は、MG12を駆動するように構成されている。なお、MG12は、本発明に係る「電動機」の一例に相当する。
図2は、比較例に係る電源回路100の構成を概略的に示すブロック図である。この比較例の電源回路100と対比しつつ、実施の形態1に係る電源回路30の効果について説明する。
次に、図3を参照して、本発明の実施の形態2について説明する。
図3は、実施の形態2に係る電動車両60が備える電源回路70の構成を概略的に示すブロック図である。本実施形態の電源回路70は、以下に説明する点を除き、実施の形態1の電源回路30と同様に構成されている。
以上説明した実施の形態2に係る電源回路70によっても、外部直流電源の高い供給電圧Vs(800V)を利用した急速充電時には、バッテリ16に供給される電圧は、昇降圧回路72によって800Vから400Vに降下される。このため、実施の形態1の電源回路30と同様に、急速充電時に補機部品18、20に対して高電圧が印加することを回避できる。
