Cell selection is the process of screening, evaluating, and matching individual battery cells before assembling them into modules or packs. The goal is to ensure uniformity in performance characteristics, which is critical for the safety, efficiency, and lifespan of the entire battery system.
Purpose of Cell Selection:
Minimize performance imbalance between cells
Improve cycle life and reliability of the battery pack
Reduce internal stress and avoid weak-cell dominance
Prevent early degradation, swelling, or failure
