The invention relates to an electric motor vehicle. The electric motor vehicle includes a voltage conversion circuit (20A), a primary-side smoothing capacitor (14), a battery (10), a system main relay (16), an inverter circuit (30A), a secondary-side smoothing capacitor (15), an electric motor (50), a first voltage sensor (61), a collision sensor (64), and a controller (70). The controller (70) is configured to adjust an operation of the voltage conversion circuit (20A), detect primary-side voltage by using the first voltage sensor (61) in a state that the voltage conversion circuit is operated (20A) in a case where a collision is detected by the collision sensor (64), and detect a state that the system main relay (16) is off based on a change in the detected primary-side voltage.
