摘要

针对磷酸铁锂电池组在搁置阶段出现的不均衡问题,通过电池单体开路电压与SOC的拟合方程,利用电池组中的最高电压,得到一个判断电池组不均衡性的动态阈值,并为均衡过程的实现制定了均衡控制策略,最后在MATLAB/Simulink软件平台了搭建了均衡管理模型。
        For the imbalanced problems in the suspension phase of lithium iron phosphate battery pack, through the fitting equation of the open circuit voltage of the battery cell and the SOC, using the highest voltage in the battery pack, a dynamic threshold for judging the imbalance of the battery pack was obtained, and a balanced control strategy was established for the realization of the balancing process. Finally, the balancing management model was built on the MATLAB/Simulink software platform.
