To restrain influence exerted on an electric power conversion circuit by a peripheral circuit connected to an electric power transmission route between a main machine battery and the electric power conversion circuit or influence exerted on the peripheral circuit by abnormality of the electric power conversion circuit.SOLUTION: One of a pair of DC electric power lines 30 is connected to section on a travel inverter 40 side of a positive electrode relay 12P of a positive electrode line 24P, and the other of them is connected to a section on a main machine battery 10 side of a negative electrode relay 12N of a negative electrode line 24N. A charge circuit 32 is connected to a pair of charge lines 25 and a pair of second charge lines 26. One of the pair of charge lines 25 is pulled out from between the positive electrode relay 12P and a travel inverter 40, and the other of them is pulled out from between the negative electrode relay 12N and the travel inverter 40. One of the pair of second charge lines 26 is pulled out from between the main machine battery 10 and the positive electrode relay 12P, and the other of them is pulled out from between the main machine battery 10 and the negative electrode relay 12N.SELECTED DRAWING: Figure 1

    【課題】主機バッテリと電力変換回路との間の電力伝送経路に接続された周辺回路が電力変換回路に及ぼす影響、または、電力変換回路の異常が周辺回路に及ぼす影響を抑制することを目的とする。【解決手段】一対のDC電力線30は、正極線24Pのうち正極リレー12Pの走行インバータ40側の区間に一方が接続され、負極線24Nのうち負極リレー12Nの主機バッテリ10側の区間に他方が接続されている。充電回路32は、一対の充電線25および一対の第2充電線26に接続されている。一対の充電線25は、正極リレー12Pと走行インバータ40との間から一方が引き出され、負極リレー12Nと走行インバータ40との間から他方が引き出されている。一対の第2充電線26は、主機バッテリ10と正極リレー12Pとの間から一方が引き出され、主機バッテリ10と負極リレー12Nとの間から他方が引き出されている。【選択図】図1
