To provide an electric vehicle capable of preventing a flow of a charging current or a discharging current to an unintended power storage device, with respect to two power storage devices having different use ranges to voltage.SOLUTION: A vehicle V includes an inverter 3; a first battery B1, a first power line 21, a second battery B2, a second power line 22, and a voltage converter 4. Use ranges to an open circuit voltage of the first battery B1 and the second battery B2 are not overlapped, use ranges to a close circuit voltage of the first battery B1 and the second battery B2 are overlapped. An ECU7 supplies regenerative electric power outputted from the inverter 3 to the first power line 21 is supplied to the second power line 22 through the voltage converter 4. When the second battery B2 is charged, the maximum regenerative electric power with respect to the regenerative electric power outputted from the inverter 3 to the first power line 21 is calculated on the basis of the open circuit voltage of the first battery B1, and the inverter 3 and the voltage converter 4 are controlled so as to prevent the regenerative electric power from exceeding the maximum regenerative electric power.SELECTED DRAWING: Figure 1

    【課題】電圧に対する使用範囲が異なる2つの蓄電装置に対し、意図しない蓄電装置に充電電流や放電電流が流れるのを防止できる電動車両を提供すること。【解決手段】車両Vは、インバータ3と、第1バッテリB1と、第1電力線21と、第2バッテリB2と、第2電力線22と、電圧変換器4と、を備える。開回路電圧に対する使用範囲は第1バッテリB1と第2バッテリB2とで重複しておらず、閉回路電圧に対する使用範囲は第1バッテリB1と第2バッテリB2とで重複している。ECU7は、インバータ3から第1電力線21へ出力される回生電力を、電圧変換器4を介して第2電力線22に供給し、第2バッテリB2を充電する場合には、第1バッテリB1の開回路電圧に基づいてインバータ3から第1電力線21へ出力される回生電力に対する最大回生電力を算出し、回生電力が最大回生電力を超えないようにインバータ3及び電圧変換器4を制御する。【選択図】図1
