混合动力汽车复合电源的设计

Design of hybrid power system for hybrid electric vehicle

在运用混合动力汽车(HEV)电池和超级电容(UCs)的基础上,设计了一种新型的超级电容-蓄电池复合电源的HEV控制系统(包括一个DC-DC转换器)。在高功率需要时,UC通过DC-DC与电机相连。实验结果表明,该复合电源电动车能兼顾蓄电池和超级电容的优点,可以更好地满足电动车启动和加速性能的要求,并能提高电动车制动能量回收的效率,增加续驶里程,降低了起动污染物的排放,提高了燃油的经济性。

In this paper, a new type of super capacitor-HEV battery composite power control system （including a DC-DC converter） was designed based on the use of hybrid electric vehicle （HEV） battery and super capacitor （UCs）. UC was connected with the motor through DC-DC when high-power was needed. The experimental results show that the composite power supply batteries for electric vehicles are able to take advantage of super capacitor and can better meet the needs of the electric car start-up, speed up the performance requirements, improve the electric vehicle braking energy recovery efficiency, increase mileage continued drive to reduce the start of the emissions of pollutants, and increase the fuel economy.
