根据北京某公交行驶工况研究的结果,对燃料电池城市客车动力系统进行了构型选择和主要参数匹配,然后在Matlab/Simulink软件中利用封装技术建立了详细的整车动力系统仿真模型,对其工况跟踪和动力电池特性进行了仿真研究。仿真结果说明了整车动力系统的设计和参数匹配比较合理,能够满足北京公交的运营需要,同时也说明了仿真模型是正确的并且为后续详细控制算法的研究提供了基础。
According to the result of researching on the driving condition of a bus in Beijing, the configuration and main parameters of fuel cell city bus power system are matched. Then a detailed vehicle powertrain simulation model is established by Matlab / Simulink software. Its condition tracking and power battery characteristics were simulated. The simulation results show that the design and parameter matching of the vehicle powertrain are reasonable and can meet the operational requirements of Beijing bus. At the same time, it also shows that the simulation model is correct and provides the foundation for the subsequent detailed control algorithm research.
