POWER SYSTEM OF FUEL CELL VEHICLE

摘要

PURPOSE: A power system of a fuel cell vehicle is provided to simplify a circuit configuration by removing a supercapacitor blocking relay. CONSTITUTION: One end of a connection relay(112) is connected to a first contact point(152). The other end of the connection relay is connected to one end of a supercapacitor(106). A braking resistor current sensor is arranged in a line between the first contact point and one end of a braking resistor. A collector terminal of a chopper(108) is connected to the other end of the braking resistor. An emitter terminal of the chopper is connected to the other end of the supercapacitor.
