摘　　要：针对双源纯电动汽车运行中超级电容与蓄电池联合供电的能量分配问题,本文引入基于模糊控制的能量管理策略。通过将整车需求功率、蓄电池及超级电容SOC(荷电状态,State of Charge)作为模糊控制器的输入,蓄电池功率分配系数作为输出,对能量控制系统进行建模仿真。通过Simulink的仿真结果表明,该模糊控制器能够较好地分配能量,满足实车运行中的功率需求,减少大电流对蓄电池的冲击,提高蓄电池的循环利用次数,有利于汽车长时间稳定运行。According to the energy distribution problem of super capacitor and battery during the dual -energy source pure electric vehicles traveling, a energy management strategy based on fproposed. The fuzzy controller takes the required vehicle power, SOC （ State of Charge） of battery andsuper capacitor as the input, and battery power distribution coefficient as tand simulation of tlie energy control system. The simulation results of tlie energy control system blink show that tlie fuzzy controller can distrilDute the energy well and satisfy thicle operation, reducing the impact of high current on the bater, improving the number of bater recy-cling, which is conducive to long - term stable operation of tlie car.
