The fuel cell electric vehicle (FCEV) is a promising transportation technology for resolving the air pollution and climate change issues in United States. However, large-scale penetration of FCEVs would require sustained supply hydrogen which does not exist now. Water electrolysis can produce reliably sustainably if electricity grid clean, but impacts on are unknown. In this paper, we develop comprehensive framework to model FCEV-driving -refueling behaviors, water process, operation. We...

This paper presents an optimized energy management strategy for Li-ion power batteries used on electric vehicles (EVs) at low temperatures. In low-temperature environments, EVs suffer a sharp driving range loss resulting from the and capability reduction of battery. Simultaneously, because Li plating, battery degradation becomes increasing concern as temperature drops. All these factors could greatly increase total vehicle operation cost. Prior to charging operating, preheating...
