摘要： 针对多能量源复合燃料电池电动客车的开发，以燃料电池+ 动力电池+ 超级电容型复合电源 系统为研究对象，基于 MATLAB/Simulink/Stateflow 搭建了整车数学模型；基于动力性、经济性指 标与三能量源特性完成了动力系统和复合电源系统的参数匹配与校核，提出了以燃料电池输出功率为主、 动力电池输出功率为辅、超级电容防止燃料电池与动力电池过载为原则的逻辑门限值控制策略，并基 于中国典型城市循环工况和长春城市公交工况进行了仿真验证。仿真结果表明：整车最高车速为 73 km/h，最大爬坡度为 22 %，0~50 km/h 加速度时间为16.7 s，中国典型城市工况下续驶里程为 263 km，长春城市工况下续驶里程为 282 km。因而，整车动力性、经济性指标均满足设计要求。

Abstract: For development of fuel cell electric buses with multi-energy-source composite, taking multi-energysource composite of fuel-cell + power-cell + ultra-capacitor as research object, a vehicle mathematical model was built based on MATLAB/Simulink/Stateflow. Based on power index, economy index and characteristics of three energy sources, parameter matching and checking of multi-energy-source system were completed. Based on principle that fuel cell is main energy source, battery is auxiliary, and ultra-capacitor prevents overload of fuel cell and battery, control strategy of logic threshold was proposed. And simulation verification was finished under Chinese typical city circle and Changchun driving cycle. Simulation results show that maximum vehicle speed is 73 km/h, maximum climbing gradient is 22%, and acceleration time from 0 to 50 km/h is 16.7 s. Driving range under Chinese typical city circle is 263 km and that in Changchun driving cycle is 282 km and power and economic indexes of vehicle exceed design requirements.
