Abstract
An electric vehicle includes: a motor for traveling; a transmission connected to the motor; a battery; an inverter configured to convert direct-current power output by the battery, into alternating-current power for driving the motor; a capacitor connected between a positive electrode of direct-current input terminals of the inverter and a negative electrode of the direct-current input terminals of the inverter; and a controller configured to change a gear stage of the transmission when both of a condition i) and a condition ii) are satisfied. The condition i) is a condition that the rotation speed of the motor is in a predetermined range. The condition ii) is a condition that the output of the motor exceeds a predetermined output threshold.
