摘要： An electric vehicle includes front and rear wheels, a battery, an electric motor that drives at least one of the front and rear wheels, an accelerator, and a mode shift operator that is operated by a user in order to switch drive modes. The electric vehicle includes a driving force characteristics setter that sets, for each of the plurality of drive modes, driving force characteristics which are characteristics of an accelerator opening degree and a target motor driving force for the rotational speed of the electric motor. The electric vehicle further includes a controller which shifts up, according to an operation of the mode shift operator, the drive mode from a first drive mode to a second drive mode and which controls the target motor driving force according to the driving force characteristics. When a shift-down prohibition condition is met, the controller prohibits a shift down from the second drive mode to the first drive mode.

摘要： A battery with increased capacity is provided in a straddled electric vehicle including a drive unit provided on a rear arm for supporting a rear wheel such that the rear wheel is rotatable. A power supply unit is located in a vehicle body frame to supply electric power to the drive unit. The drive unit includes a motor that overlaps the rear wheel in a side view of the vehicle. The power supply unit includes a battery and a controller. The controller supplies electric power stored in the battery to the drive unit. The vehicle body frame includes a head pipe and a pivot shaft. The pivot shaft supports the rear arm such that it is swingable. The power supply unit is located between the head pipe and pivot shaft in a side view of the vehicle.
