Research on Hybrid Energy Storage System Energy Management Based on Improved Working Mode

针对峰值电流影响蓄电池寿命问题,利用超级电容比功率高,不受大电流充放电影响等优势,与蓄电池组合成复合电源,通过在传统复合电源的工作模式中增加超级电容器组单独工作的改进工作模式,制定逻辑门限控制策略来解决这一问题,并在高级车辆仿真软件ADVISOR中进行仿真验证。结果证明该方法使流过蓄电池的电流幅值降低了36.6%,有效的延长蓄电池的循环使用寿命。

According to peak current effect of the life of storage battery,the advantages of ultra-capacitor,high power,and high current charging and discharging are combined with batteries to form a hybrid energy storage.By adding an improved working mode of the ultra-capacitor group working alone in the working mode of the traditional composite power supply,a logic threshold control strategy can be used to solve this problem,and the simulation is verified in the advanced vehicle simulation software ADVISOR.The result proves that the method reduces the current amplitude of the current flowing through the battery by 36.6%,effectively extending the cycle life of the battery.
