Fuel economy is an important index for fuel cell hybrid powertrain system. Because fuel economy can be affected by control strategies, test protocols and system design, traditional economy analysis method should calculate all fuel economy results under different strategies and protocols. In this paper, a three-step evaluation method has been proposed for fuel cell hybrid powertrain system fuel economy analysis. For a fuel cell hybrid system system, effeciency curve is used for fuel cell system economy analysis, average power demand variation is used for fuel cell hybrid system economy analysis, output power histogram is used for energy management strategy analysis. It has been validated that this method can be used to guide the system design and fuel economy evaluation.
