ELECTRIC VEHICLE CONTROL DEVICE AND CONTROL METHOD

摘要

In order to reliably discharge a fuel cell stack when a vehicle collides, an electric vehicle comprises: a fuel cell stack that generates power by an electrochemical reaction between a fuel gas and an oxidation gas and supplies the generated power to a vehicle drive electric motor; a first discharge electric resistor (81) electrically connected through an electrically controlled discharge switch (82) to the fuel cell stack; a discharge control circuit (90) for controlling the turning on and off of the discharge switch; and a collision detector for detecting a vehicle collision and outputting a collision signal to the discharge control circuit. The discharge control circuit turns on the discharge switch when the collision signal is input to electrically connect the fuel cell stack to the first discharge electric resistor, thereby allowing the fuel cell stack to be discharged. The power for the discharge control circuit is supplied from the fuel cell stack.
