Beyond the end of charging.
Balance throughout operation.
Cell differences persist after charging ends. Conventional balancing has a short window and limited cumulative effect. All-time Balancing extends the available window to address differences throughout operation.

IC CURVE ANALYSIS
Insight without a rest period.
When no rest period is available, use characteristic peak spacing in IC curves to assess cell capacity and calculate the capacity to balance, informing balancing duration.
Peak spacing ∝ Cell capacity
