燃料电池城市客车动力驱动系统的合理匹配研究

为实现国家"十一五"863重大科研项目——燃料电池城市客车专项的燃料电池城市客车动力性能指标,建立了燃料电池城市客车的整车动力系统结构形式,进而完成新样车的概念设计。对实际目标样车动力驱动系统不同部件(包括电机、变速器、燃料电池、蓄电池)性能参数的合理匹配理论和过程进行了详尽的研究。建立了基于电压控制策略的动力驱动系统仿真模型。仿真结果达到目标样车的动力性能指标,同时建立的仿真模型对进一步深入研究整车控制策略的优化具有重要指导意义。匹配理论和仿真模型对其他类型的电动汽车研究具有一定的参考价值。

Research on Reasonable Matching of Powertrain of Fuel Cell City Bus

In order to realize dynamic performance indices on Fuel Cell City Bus(FCCB),the powertrain configuration of the whole vehicle was established,and then the conceptual design of a new prototype vehicle was completed.The theory and process of performance parameters reasonable matching for different comPonents (including motor,gearbox,fuel cell,battery)of real target prototype vehicle powertrain were discussed in detail. The simulation model of powertrain based on voltage control strategy was built.The simulation results meet dynamic performance indices of target prototype vehicle.Meanwhile,the simulation model has instructional significance for the optimization of the whole vehicle control strategy profoundly.The matching theory and simulation model have a certain reference value for other types of electric vehicles.
