Abstract

Lithium-ion power batteries are used in groups of series-parallel configurations. There are Ohmic resistance discrepancies, capacity disparities, and polarization differences between individual cells during discharge, preventing a single cell from reaching the lower limit of the terminal voltage simultaneously, resulting in low capacity and energy utilization. The effect of the parameter difference (difference in parameters) of individual cells on the performance of the series-parallel battery pack is simulated and analyzed by grouping cells with different parameters. The findings reveal that when cells are connected in series, the capacity difference is a significant factor impacting the battery pack's energy index, and the capacity difference and Ohmic resistance difference are significant variables affecting the battery pack's power index. When cells are connected in parallel, the difference in Ohmic internal resistance between them causes branch current imbalance, low energy utilization in some individual cells, and a sharp expansion of unbalanced current at the end of discharge, which is prone to overdischarge and shortens battery life. Interestingly, we found that when there is an aging cell in a series-parallel battery pack, the terminal voltage of the single battery module containing the aging single cell will decrease sharply at the end of discharge. Evaluating the change rate of battery module terminal voltage at the end of discharge can be used as a method to evaluate the aging degree of the battery module. The research results provide a reference for connecting batteries to battery packs, particularly the screening of retired power battery packs and the way to reconnect into battery packs.

摘要

锂离子动力电池采用串并联配置成组使用。在放电过程中，各个电池之间存在欧姆电阻差异、容量差异和极化差异，导致单个电池无法同时达到端电压下限，从而造成容量和能量利用率较低。通过对具有不同参数的电池进行分组，模拟分析了单个电池的参数差异（参数不同）对串并联电池组性能的影响。研究结果表明，当电池串联连接时，容量差异是影响电池组能量指标的重要因素，容量差异和欧姆电阻差异是影响电池组功率指标的重要变量。当电池并联连接时，它们之间的欧姆内阻差异会导致支路电流不平衡，一些单个电池的能量利用率较低，并且在放电末期不平衡电流会急剧增大，容易发生过放电，缩短电池寿命。有趣的是，我们发现当串并联电池组中有一个老化电池时，包含老化单节电池的单电池模块的端电压在放电末期会急剧下降。评估放电末期电池模块端电压的变化率可作为评估电池模块老化程度的一种方法。研究结果为电池连接到电池组提供了参考，特别是退役动力电池组的筛选以及重新连接到电池组的方式。
