摘　　要：以超级电容与双向DC/DC变换器串联再与蓄电池并联的复合电源为研究对象,提出一种逻辑门限控制与模糊控制相结合的复合电源功率分配控制策略。首先利用Matlab/Simulink软件建立复合电源功率分配控制策略模块;然后运用ADVISOR软件进行二次开发,搭建纯电动汽车整车仿真模型;最后结合城市道路驱动工况进行仿真分析。结果表明,基于该控制策略的复合电源能够有效地节省蓄电池的电量,延长复合电源的工作寿命,纯电动汽车的动力性能和续驶里程明显提升。A power distribution control strategy of compound power supply combining logic threshold control and fuzzy control is proposed.In this paper,the compound power supply(the super⁃capacitor is connected with bi⁃directional DC/DC converter in series and then connected with accumulator in parallel)is taken as the research object.Firstly,the Matlab/SIMULINK software is used to build the power distribution control strategy module of compound power supply.Then,the ADVISOR software is used for secondary development to construct the vehicle simulation model for the pure electric vehicle(PEV).Finally,the simulation analysis is made on the basis of driving conditions of urban roads.The results show that the compound power supply on the basis of the control strategy can effectively save the accumulator power,prolong the service life of the compound power supply,and significantly improve the power performance and total mileage of the pure electric vehicle.
