摘要
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。
Energy storage system widely used in hybrid electric vehicles is a single battery energy system,and its battery life cannot be used to maximization nowadays.For solving this problem,ultracapacitors were added into the structure of hybrid electric vehicle.After analyzing the principle and characteristics of ultracapacitor,the model of battery pack and ultracapacitor in parallel connection was established in Matlab/Simulink,hybrid energy storage system（HESS） control strategy was joined,and the topology of the HESS and type of each component were designed,and secondary development for composite power control strategy in Advisor was made.Then,the performance and fuel economy between HESS-powered vehicle and single battery-powered vehicle were compared.The results show that large current charge-discharge of battery pack can be reduced obviously by hybrid energy storage system powered hybrid vehicle,and the dynamic performance and fuel economy of hybrid electric vehicle can be improved as well.
