摘要
为合理分配燃料电池/蓄电池电源投入的功率及很好地保护蓄电池,本文利用Matlab/Simulink搭建了燃料电池/蓄电池混合动力汽车整车系统模型,并基于燃料电池系统的功率效率曲线,设计了其能量管理系统(energy management system,EMS),根据蓄电池的荷电状态(state of charge,SOC)和负载需求功率分为14种状态,以此确定燃料电池系统的输出参考功率,在合理保护蓄电池的同时,尽可能地提高燃料电池系统的输出效率。为测试该能量管理系统对燃料经济性的改善程度,本文在Matlab/Simulink环境下进行仿真模拟。仿真结果表明,与基于功率追踪的EMS相比,本文提出的EMS蓄电池储存的电能更高,可以有效地减少氢气的消耗,同时使蓄电池的SOC保持在合理区域,使混合动力汽车具有更好的经济性和安全性。该研究具有重要的经济实用价值。
In order to reasonably allocate fuel cell and battery input power and protect battery well,a vehicle fuel cell/battery hybrid vehicle system model is built by using Matlab/Simulink in this paper.An energy management system(EMS)is also designed based on the power efficiency curve of the fuel cell system.The control strategy is divided into 14 states according to the state of charge(SOC)of the battery and the load power to determine the output reference power of the fuel cell system.The proposed EMS can improve the output efficiency of the fuel cell system as much as possible while reasonably protecting the battery.In order to test the improvement of fuel economy,this paper simulates the EMS under the Matlab/Simulink environment.The simulation results show that,compared with the EMS based on power tracking,the proposed EMS can effectively reduce the hydrogen consumption and store higher electrical energy,which makes the hybrid vehicle have better economy and safety.The study has important economic and practical value.
