摘要
针对燃料电池混合动力汽车(Fuel Cell Hybrid electric Vehicle,FCHV)在频繁变载、启停、连续低载和怠速工况下燃料电池寿命衰减的现状,提出基于模糊控制与开关控制的滑动平均滤波复合能量管理策略,该复合能量管理策略以整车需求功率与燃料电池高效区下限之差和蓄电池SOC为模糊输入量,在有效避免燃料电池启停、连续低载和怠速工况的同时,通过开关控制可避免蓄电池过充产生的安全问题,通过滑动平均滤波控制可以改善燃料电池在频繁变载工况下耐久性差的问题。采用AVL Cruise软件和Matlab/Simulink软件进行联合仿真,仿真结果表明,提出的复合能量管理策略在保证蓄电池安全性的情况下,减少了引起燃料电池寿命衰减的工况,提升了燃料电池的耐久性。
In view of the Fuel Cell Hybrid electric Vehicle(FCHV)life decay under the condition of frequent load change,start stop,continuous low load or idle speed,a sliding average filter composite energy management strategy based on fuzzy control and switch control was proposed.The energy management strategy was based on the difference between the vehicle demand power and the lower limit of fuel cell high efficiency area and the power storage pool SOC was a fuzzy input,which can effectively avoid the start and stop,low load and idle conditions of the fuel cell,while the switch control can avoid the safety problems caused by the overcharge of the battery,and the poor durability of the fuel cell under frequent load changing conditions can be improved by the sliding average filter control.Joint simulation with AVL Cruise and Matlab/Simulink,the simulation results show that the proposed composite energy management strategy can reduce the working conditions that cause the life decay of fuel cell and improve the durability of fuel cell while ensuring the safety of battery.
