为了解决目前国内混合动力电动汽车普遍采用的是单一蓄电池供电能量存储系统,蓄电池的寿命不能最大化的利用这一问题,在混合动力结构中加入了超级电容器组,分析了超级电容的原理与特性后,在Matlab/Simulink里建立了蓄电池组与超级电容组成的复合电源系统模型,并确定了复合电源系统的拓扑结构以及各元件的选型以及参数匹配,加入复合电源控制策略,并对Advisor进行了二次开发,对比复合电源供电的车辆与单一蓄电池供电在性能与燃油经济性方面的差异。结果表明复合电源系统供电的混合动力车辆能够减小蓄电池组的大电流充放电,并且能够提高混合动力汽车的动力性和燃油经济性。
In order to solve the problem that the battery electric energy storage system is commonly used in domestic hybrid electric vehicles at present, the lifetime of the battery can not be maximized, a supercapacitor bank is added into the hybrid power structure to analyze the principle and characteristics of the supercapacitor After that, a model of composite power system composed of battery and supercapacitor was established in Matlab / Simulink, and the topology of the composite power system and the selection of components and matching of parameters were determined. The composite power control strategy was added and Advisor The second development, comparing the difference between performance and fuel economy of a hybrid powered vehicle and a single battery. The results show that the hybrid power supply system of hybrid vehicles can reduce the large current charging and discharging of the battery pack, and can improve the power and fuel economy of the hybrid vehicle.
