Abstract:The parameter matching of the power system is an important part of the design of the fuel cell electric vehicle, which directly affects the power and fuel economy of the vehicle. Taking a certain extended fuel cell car as the research object, the parameter matching and key component selection in the design of the extended fuel cell electric vehicle power system were studied. The structure and working mode of the power system of the FCV are clarified. The parameters matching and selection of the fuel cell engine system, the drive motor and the battery are carried out according to the dynamic performance and economic indicators of the vehicle. The ADVISOR2002 vehicle simulation software is used. The vehicle's power and economy are simulated. The simulation results show that the determined power system scheme can meet the vehicle performance requirements and verify the rationality of vehicle parameter matching and selection.Keywords: Parameter matching; Power system; Extended fuel cell vehicle; Performance simulationCLC NO.:TK411  Document Code: A  Article ID: 1671-7988(2019)23-01-04

引言

燃料電池电动汽车因具有零排放、效率高、能源可再生、多元化等优点,成为全球各大汽车公司的研究热点[1-3]。自 20世纪 80年代起,奔驰、丰田、本田、通用等汽车公司对燃料电池电动汽车进行了近 40 年的研究,其整车性能和可靠性已与传统汽车相当,正处于产业化前期[4-6],但相关的匹配设计技术尚不完善。

合理地选择动力系统的参数,才能充分保证 FCV的整车动力性和续驶里程的要求。文中首先介绍了 FCV动力系统的结构配置和工作模式;然后以 FCV 整车动力性能指标和续驶里程要求为约束条件,对 FCV开展了动力系统各部件的参数匹配设计,最后,使用以ADVISOR2002汽车仿真软件进行了仿真验证。
