摘要
the inconsistency of the battery cells has a great impact on battery grouping performance. In this paper, the inconsistency effect of internal resistance is analyzed by using the series-connected Rint battery model. And the difference of the parameter definition between the battery cell and the battery strings is analyzed. Through the theory analysis and simulation verification, some principles of battery cells grouping are achieved, which has an important reference significance to guide how to select and classify battery cells in the battery strings for better performance.
