Power Control and Optimization of Fuel Cell Hybrid Vehicle

研究一种低成本、高性能的三能源(燃料电池,动力蓄电池和超级电容)plug-in混合动力系统方案。比较多种能量控制策略,采用适合该系统的逻辑门限控制策略,并基于Matlab/Simulink编写程序,建立仿真车型进行控制策略仿真;分析ECE-EUDC循环工况下该系统的扭矩、功率的分配以及行驶状态的变化,并优化重要门限参数使整车系统达到最优状态。仿真结果表明,燃料电池汽车三能源混合系统能够在满足动力性的前提下,稳定高效运行,降低能耗,改善经济性。

This paper concentrates on the power distribution of fuel cell hybrid vehicle and proposes a low-cost and high-performance multiple dynamic system which is consisted of fuel cell,battery pack and ultra-capacitor.The logic gateway control strategy is applied and simulated in the Matlab/Simulink vehicle model.The changes of vehicle power and running states which operated on ECE-EUDC road cycle are demonstrated and analyzed.The key parameters of the logic gateway control strategy are then optimized and the results of the simulation show that the strategy on this vehicle system can effectively ensure the fuel cell engine,battery pack and ultra-capacitor perform smoothly with high efficiency and low energy consumption.
