The electric vehicle includes a first battery, a second battery having an output weight density higher than that of the first battery and an energy weight density lower than that of the first battery, a motor generator, an electric power conversion circuit, and a control device for controlling the electric power conversion circuit. The control device controls the electric power conversion circuit so that, during a powering operation of the motor generator, at least a part of electric power necessary for changing a vehicle speed among requested electric power is discharged from the second battery, and remaining electric power obtained by subtracting the electric power discharged from the second battery from the requested electric power is discharged from the first battery; and it controls the electric power conversion circuit so that, during a regenerative operation of the motor generator, electric power generated is charged to the second battery.
