In short, the consistency of each cell's voltage, internal resistance, capacity and self-discharge rate (K-value) is crucial for a pack's safety, efficiency and lifespan. When cells are matched (like synchronized rowers), they share current evenly and age together. . Battery packs in EVs, storage systems and consumer devices rely on well-matched cells. Therefore, this paper focuses on the consistency modeling and state. . Cell consistency refers to the degree of difference between the performance parameters (such as capacity, internal resistance, voltage, etc.

How to evaluate the consistency of a battery pack?
Feature selection To comprehensively evaluate the consistency of a battery pack, it is necessary to simultaneously consider the differences in its voltage, internal resistance, capacity, temperature, and other relevant factors.
What is inconsistency in a battery pack?
In conclusion, inconsistency in a battery pack can be defined as the combined discrepancy in the capacity, internal resistance, and self-discharge rate of the battery cells, among other factors. Information fusion-based methods are more appropriate for evaluating the level of consistency.
Are battery pack consistency indicators based on multi-feature weighting?
Conclusions This study extracts four-dimensional consistency indicators of temperature, voltage, capacity, and resistance based on large-sample battery data and proposes a battery pack consistency evaluation scheme based on multi-feature weighting.
Can information fusion improve the consistency of battery packs?
This study proposes a consistency evaluation scheme based on information fusion, which comprehensively and accurately evaluates the consistency of battery packs in actual operation by integrating multiple factors, providing an effective guide for management optimization.
