Below are two Tesla charging examples. Both show cell voltage behavior during charging. The difference becomes clear near the upper SOC range. One case shows balancing recovery.The other shows a condition where balancing can no longer recover the imbalance. Case 1: Balancing Recovers In the first graph, look at the circled area near high SOC. As charging progresses, the thickness of the cell voltage band becomes thinner. The spread between the highest and lowest cells gradual
