Alternative power sources for internal combustion engine (ICE) have been researched recently in order to cope with environment problems. Fuel cell is regarded as one of the most promising power generation device, because it can generate propulsion energy without harmful exhaust gases. This paper proposes a fuzzy controller for optimal power management of a fuel cell hybrid electric vehicle (FCHEV). A dynamic model of electric powertrain of the FCHEV is derived to establish power distribution strategy. The power distribution strategy is implemented with fuzzy controller. Then, the fuzzy controller is optimized using a genetic algorithm. The optimization process of the fuzzy controller is accomplished for a given driving cycle. Finally, the simulation results of the optimized fuzzy controller shows the improved performance in terms of minimum fuel consumption and SOC maintenance.
