摘　　要：针对新能源汽车用单一电源的使用寿命短、不能同时满足高能量密度和高功率密度需求等问题,提出一种蓄电池超级电容器混合电源方案。该方案充分发挥了超级电容器快速充放电的特性,采用2种电源直接并联,并通过一种双向功率变换器变压向负载供电,可同时实现充足的能量供应和功率需求。建立了MATLAB/SIMULINK仿真模型,并搭建小功率实验平台,仿真及实验结果表明,混合电源系统具有良好的电能输出响应特性,能量回收快,可减少蓄电池的供电工况,从而延长其使用寿命。In order to solve the problems of a single battery power source for new energy vehicle such as short service life and low power density,a battery-supercapacitor hybrid power source is proposed in this paper.The hybrid power source brings into full play the role of the fast charging/discharging property of super-capacitor,and utilize two parallel power sources,finally provides the load the supply by a bidirectional power-converter,thus realizing steady energy supply and power requirement.A MATLAB/SIMULINK model is established,and a lowpower experiment platform is built.The simulation and experimental results show that the hybrid power source has good power output characteristic,high rate of braking energy recovery,thereby reducing the battery supply and lengthening its service life.
