An electric vehicle of the present disclosure includes a heat exchange system that transfers heat occurring in a three-phase alternating current motor to a battery, a coil cooling device configured to cool each of three-phase coils individually, and a controller that executes a heat generation control that controls the power control device such that direct current flows through each of the three-phase coils in response to satisfaction of a predetermined condition while the electric vehicle is stopped, and while the heat generation control is executed, controls the coil cooling device to cool the coil with a largest current flowing among the three-phase coils, and controls the power control device to increase the largest current. During the electric vehicle is stopped, it allows the three-phase alternating current motor to generate more heat while protecting the three-phase coils of the three-phase alternating current motor.
