摘要
为优化电动汽车充电电池的供电性能,研究电动汽车充电站动力电池并联重组供电均衡性。通过串并联转换方式对动力电池完成并联重组。并在并联重组的电池上安装供电均衡性控制器,确定控制运行周期、导通占空比等作为均衡控制参数,进而实现对并联重组动力电池的供电均衡性控制。通过应用实验可得出结论:所提方法应用下,电动汽车充电站动力电池的供电电压的时序均衡指标、空间均衡度指标、放电量偏差和负载标准差均满足应用要求,由此证明设计方法控制效果较好。
In order to optimize the power supply performance of electric vehicle charging battery,the power supply balance of par-allel reorganization of power battery in electric vehicle charging station is studied.The power battery is reorganized in parallel through series parallel conversion.The power supply balance controller is installed on the parallel reconstituted battery,and the control operation cycle and on duty cycle are determined as the balance control parameters,so as to realize the power supply bal-ance control of the parallel reconstituted power battery.Through the application experiment,it can be concluded that under the application of the proposed method,the timing balance index,spatial balance index,discharge deviation and load standard de-viation of the power battery of the electric vehicle charging station meet the application requirements,it is proved that the control effect of the design method is better.
