The battery pack is idle and there is no current flowing through it. The cell balancing algorithm activates when the minimum difference in the cell state of charge is greater than 0.05% and the battery pack is idle. The algorithm charges closes switches for all cells other than the one with lowest state of charge.
Simultaneous cell balancing can also be accomplished for multiple cells at once by means of comparator-based circuit solutions which facilitate the decision of bypass or energy transfer considering the entire battery pack. Anton Beck, “Why proper cell balancing is necessary in battery packs”, Battery Power.
The inherent differences and discrepancies among individual cells within a battery pack give birth to the need for battery balancing. Production differences, aging, temperature effects, or differing load conditions can cause these inequalities. Cells are joined end-to-end, and the same current moves through each cell in a series configuration.
So, the only solution is to use an external system that forces the cells to get balanced again after they get unbalanced. This system is called the Battery Balancing System. There many different types of hardware and software techniques used for battery cell balancing. Let is discuss the types and widely used techniques.
Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity. A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing.
Cell balancing is all about the dissipation or movement of energy between cells. The aim being to align them all with respect to state of charge. Aligning the state of charge of all of the cells in a pack will allow the pack to deliver the most energy and power.
