Abstract:

High cost of new energy vehicles (NEVs) is one of the most important factors restricting its development in China. In this study, a comprehensive model for economy analysis and comparison of battery electric vehicles (BEV) and fuel cell electric vehicles (FCEV) is constructed. Based on the learning rate curves of major components of NEVs, the future manufacturing cost trends of battery electric and fuel cell passenger cars, buses, and trucks are analyzed and compared. At the same time, combined with the four application scenarios of private car, taxi, bus and logistics vehicle in China, the use cost of battery electric vehicles and fuel cell electric vehicles in each application scenario is analyzed. Finally, the total cost differences between the two technical routes at different time points in the future are compared. The result shows that although the manufacturing cost of range?extended fuel cell vehicles will be lower in the future, the cost advantage of BEVs is distinct, with its total cost more competitive.
