Battery balancing is crucial to potentiate the capacity and lifecycle of battery packs. This paper proposes a balancing scheme for lithium battery packs based on a ring layered topology. Firstly, a two-layer balanced topology based on a Buck–Boost circuit is proposed. Then, an adaptive fuzzy logic controller (AFLC) is adopted to adjust …
As some cells may charge or discharge faster than others, this discrepancy can result in a state of imbalance across the battery pack. The Benefits of Balanced Cells. Lithium-ion cells are sensitive to extreme conditions, especially high voltage situations. Without balancing, some cells can become overcharged or discharged more than others.

As depicted in Fig. 7 b, the battery pack without balancing performs as well as the one with dissipative balancing in case of no self-discharge variation. However, an increase in relative variance of the self-discharge deteriorates the overall discharge energy of the battery pack without balancing, reaching 96.8% for doubling the relative …
Contributed Commentary by Anton Beck, Battery Product Manager, Epec. When a lithium battery pack is designed using multiple cells in series, it is very important to design the electronic features to continually balance the cell voltages. This is not only for the performance of the battery pack, but also for optimal life cycles.
This example shows how to implement a passive cell balancing for a Lithium-ion battery pack. Cell-to-cell differences in the module create imbalance in cell state of charge and hence voltages. In this example, …
