摘要
近年来大量退役的动力电池给社会带来压力,退役电池梯次利用是最理想的应用.使用容量、内阻对比法研究电池成组特性,结果发现并联电池内阻与电池组容量存在线性关系,在相同时间内同内阻电池的充入容量与原容量成正相关,相同容量电池的充入容量与原内阻成负相关,这个规律优化了退役电池梯次利用串并联方案,有利于退役电池组的梯次利用.
In recent years,decommissioned power batteries have brought pressure to society,and the cascade utilization of decommissioned batteries are the most ideal application.In order to study the seriesparallel characteristics of power battery pack after decommissioning,the method of capacity and internal resistance comparison was used to study the characteristics of battery packs.The results showed that there was a linear relationship between the parallel internal resistance and the capacity and internal resistance of battery pack.It was positively correlated with the capacity of internal resistance battery pack and negatively correlated with the capacity of capacity battery pack and the original internal resistance.The cascade and parallel connection scheme of decommissioned batteries is optimized regularly,which is conducive to better cascade utilization of batteries.
