摘　　要：针对以蓄电池为单一车载电源的纯电动汽车存在着功率密度低、能量密度低、使用寿命短等缺点,将超级电容引入到纯电动汽车的储能系统中,组成了超级电容—蓄电池的复合电源结构。在MATLAB/SIMULINK环境下建立复合电源储能系统和驱动系统的仿真模型。基于搭建的实验平台参数,以可能多地利用电机再生制动力、最大程度实现制动能量的回收为目的制定制动力分配控制策略,根据标准市区循环工况进行再生制动仿真实验。结果表明,此再生制动系统回收了24%的制动能量,可以很好地弥补了蓄电池的低功率密度和低能量密度等缺陷,提高车载能量的利用率和车辆的动力性能,延长电动车的续驶里程。Because storage battery used for driving the electric vehicle only has low power density, low energy density and other disadvantages, supercapacitor was applied to the energy storage system in battery electric vehicle to form a multiple energy supply system with battery. The multiple energy supply system model and driving system model were established via simulation environment of MATLAB/SIMULINK. In order to use more motor regenerative braking force and maximize braking energy recovery module, the braking force distribution control strategy was developed based on ex- periment platform parameter. The regenerative simulation test was conducted according to the power demands under standard urban driving cycle. The result shows that the regenerative braking system can recycled 24% braking energy. The multiple energy supply system can make up for the low pow- er density, low energy density and other defects of car battery very well. It can improve the energy utilization ratio and the dynamic performance of the vehicle, and extend the driving range of electric cars.
