摘　　要：针对蓄电池单独作为汽车电源不能满足纯电动汽车短时间功率的需求问题,可采用超级电容与双向DC/DC串联再与蓄电池并联的复合电源来满足汽车功率的需求。利用模糊控制工具箱设计对于复合电源功率分配的模糊控制器,搭建整车复合电源控制策略模块,应用Cruise软件快速完成整车模型的搭建,将控制策略添加到整车模型中。仿真结果表明,纯电动汽车复合电源控制策略能够有效地分配蓄电池和超级电容的功率,从而使超级电容充分发挥"削峰填谷"的作用。Aiming at the problem that the battery power supply cannot meet the demand of short time power of blade electric vehicle, the hybrid power system composed by the super capacitor and bi-directional DC/DC in series with the battery parallel is adopted to satisfy the requirement of the vehicle. The fuzzy control toolbox is taken to design fuzzy controller for composite power distribution and build the hybrid power control strategy module. Cruise software is adopted to complete the vehicle model quickly and the control strategy is added to the vehicle model. The results show that blade electric vehicle hybrid power system control strategy can effectively allocate the power between the battery and the super capacitor so as to make the super capacitor give full play to ＂cut peak and fill valley＂.
