The power matching of fuel cell vehicles is a very important part of the research and development design of fuel cell vehicles,which directly affects the power and economy of fuel cell vehicles.However,there is currently no mature method for power system parameter matching on the market.Considering the above situation,combined with the developed full power and hybrid architecture models,based on vehicle indicators,combined with dynamic theory and testing experience,a fuel cell vehicle powertrain parameter matching method is proposed.Full-power and hybrid models are selected for actual vehicle verification,further confirming the rationality of the vehicle power matching method,It has good reference significance for the integration of fuel cell vehicle power matching and parameter selection.
