Abstract
An electric vehicle includes: a motor to propel the electric vehicle; a secondary battery that exchanges power with the motor via a power line; a capacitor that is connected to the power line; a collision detection unit that detects a collision of the electric vehicle; a rotation speed detection unit that detects a rotation speed of the motor; and a control unit that, when a collision of the electric vehicle is detected and the detected rotation speed of the motor equals or exceeds a predetermined rotation speed, controls the motor such that the rotation speed of the motor falls below the predetermined rotation speed and then executes discharge control to discharge the capacitor.
