在分析复合电源结构的基础上，建立复合电源 DC/DC 仿真子模块，制定基于功率需求分配的模糊控制策略，建立模糊控制复合电源仿真模型，并在汽车仿真软件 ADVISOR 平台上对其进行二次开发，搭建模糊控制复合电源系统的纯电动汽车仿真模型。以 UDDS 工况为例进行仿真分析，结果表明，该模糊控制复合电源系统能合理分配蓄电池和超级电容的功率输出，超级电容能在汽车加速时提供瞬时峰值功率，延长了蓄电池的使用寿命，提高了车载电源的整体性能。

Based on the analysis of composite power source structure,a DC/DC simulation sub-modular of composite power source was built,and then a fuzzy control strategy based on power demand allocation was developed in this paper.A composite power source simulation model based on fuzzy control strategy was thus set up,and then a model of pure electric vehicle with compos-ite power source system was built by secondary development of ADVISOR simulation software. The model was carried out with the UDDS operating condition.The simulation results show that the composite power source system can properly distribute the battery energy and ultra-capacitor power output,and the ultra-capacitor can provide instantaneous peak power,which can prolong the service life of battery and improve the performance of vehicle power supply.
