Motor-driven vehicle

A motor-driven vehicle comprising:

• an electric motor that outputs running power;
• a drive circuit that drives the electric motor;
• a power storage device;
• a system main relay that is attached to a running electric power line connecting the power storage device to the drive circuit;
• a capacitor that is attached to the running electric power line between the system main relay and the drive circuit;
• a vehicle-side connector that is connected to a stand-side connector of a direct-current charging stand outside the vehicle;
• a charging relay that is attached to a charging electric power line connecting the vehicle-side connector to the running electric power line between the system main relay and the drive circuit;
• and
• a control device that controls the system main relay and the charging relay,
• wherein, when the stand-side connector is disconnected from the vehicle-side connector while the power storage device is being charged with electric power from the direct-current charging stand, the control device turns off the charging relay, turns off the system main relay, diagnoses a two-pole welding abnormality of the charging relay in that state, and discharges the capacitor.
