Abstract: On the basis of the green energy-saving and zero-pollution fuel cell vehicles, in order to improve the coordination stability of "electric-electric" hybrid vehicles and the efficiency of power systems, and meet the requirements of dynamic performance, the power system matching design of fuel cell/battery "electric-electric" hybrid vehicles is carried out. This paper takes fuel cell vehicles as the research object, and the selection and parameter matching of the drive motor, fuel cell system and power battery system are carried out according to the economic indicators of vehicle power performance. The degree of mixing definition is quoted and the power coordination between the fuel cell and battery hybrid systems is considered. Advisor vehicle simulation software is used to simulate various matching schemes under common working conditions. The results show that the determined power system matching design scheme has certain feasibility in terms of power performance and fuel economy, and complies with vehicle design specifications, that is, the best match between fuel cell (34 kW) and lithium-ion battery (46 kW). The reasonable power matching between the two power sources can effectively improve the power performance of the whole vehicle, ensure the economy, and thus reduce the average running cost of the vehicle.
