摘　　要：针对周期间歇性脉冲负载对蓄电池循环寿命的影响,优化蓄电池的工作状态,引入蓄电池-超级电容器复合电源解决方案,充分发挥蓄电池比能量大和超级电容器比功率大的优势.选择蓄电池与超级电容器直接并联的被动式结构复合电源作为研究对象,并对被动式结构复合电源结构进行改进.在MATLAB仿真环境下,对应用于周期间歇性脉冲负载的蓄电池单一电源、被动式结构复合电源和改进型被动式结构复合电源进行对比仿真研究,同时搭建实验平台,进行对比实验研究.仿真和实验结果均表明,改进型被动式结构复合电源相比于其他两种电源,由于超级电容器对蓄电池功率的充分补偿,蓄电池放电过程得到优化,伴随着放电电流曲线更加平滑.In view of the influence of periodic intermittent pulse load on the cycle life of the battery,and to optimize the working conditions of battery,we introduce a solution of battery-ultracapacitor hybrid energy storage system（HESS）,it can make full use of high energy density of battery and high power density of ultracapacitor.Select the passive structure of HESS which battery connects with ultracapacitor directly as the object of study,at the same time,improve the passive structure of HESS.Under the MALTAB simulation environment,the single battery,the passive structure of HESS,and the improved passive structure of HESS are chosen to simulation comparative study.Meanwhile,the experiment platform is established for comparative study.Simulation and experiment results indicate that full power compensation from the ultracapacitor on the battery optimizes the discharge process and makes the discharge current become curve more smooth.
