To provide a technique that can achieve a plurality of circuit structures, with no need of two boost converters.SOLUTION: An electric-powered vehicle comprises: a battery; an electric-powered unit; a boost converter; a charging inlet; and a connection circuit including a plurality of relays, through which the battery. the electric-powered unit, the boost converter and the charging inlet are electrically connected to one another. The connection circuit can alternatively form a power-running circuit structure, a low-voltage charging circuit structure and a high-voltage charging circuit structure, by switching the plurality of relays. In the power-running circuit structure, the battery is electrically connected to the electric-powered unit through the boost converter. In the low-voltage charging circuit structure, the charging inlet is electrically connected to the battery through the boost converter and the electric-powered unit is electrically shut off from the boost converter. In the high-voltage charging circuit structure, the charging inlet is electrically connected to the battery without interposing the boost converter therebetween and the electric-powered unit is electrically shut off from the boost converter.SELECTED DRAWING: Figure 1

    【課題】2個の昇圧コンバータを必要とすることなく、複数の回路構造を実現し得る技術を提供する。【解決手段】電動車は、バッテリと、電動ユニットと、昇圧コンバータと、充電インレットと、複数のリレーを含むとともに、バッテリ、電動ユニット、昇圧コンバータ及び充電インレットを電気的に接続する接続回路と、を備えている。接続回路は、複数のリレーを切り替えることにより、力行回路構造と低圧充電回路構造と高圧充電回路構造とを択一的に形成可能である。力行回路構造では、バッテリが昇圧コンバータを介して電動ユニットへ電気的に接続され、低圧充電回路構造では、充電インレットが昇圧コンバータを介してバッテリへ電気的に接続されるとともに、電動ユニットが昇圧コンバータから電気的に遮断され、高圧充電回路構造では、充電インレットが昇圧コンバータを介さずにバッテリへ電気的に接続されるとともに、電動ユニットが昇圧コンバータから電気的に遮断される。【選択図】図1
