<p>Provided, in an electric vehicle equipped with a discharging device for discharging a capacitor upon collision, is a technology that prevents the discharging device from being damaged due to an induced current caused by counter electromotive force of a motor. A hybrid vehicle (100) is provided with a capacitor (C1), a current sensor (14), a discharging circuit (20), and a controller (30). The capacitor (C1) is connected to the input side of an inverter (13). The discharging circuit (20) is connected in parallel to the capacitor (C1). The current sensor (14) measures an induced current caused by counter electromotive force of a motor (MG). When a signal indicating abnormality or collision is inputted into the controller (30), the controller (30) activates the discharging circuit (20) when the magnitude of the induced current measured by the current sensor (14) is less than a prescribed threshold current value, and does not activate the discharging circuit (20) when the magnitude of the counter electromotive force current is more than the threshold current value.</p> |
