Lithium ion cell imbalance

WebWe present a novel approach for a battery management system in which adaptive thermal control is employed to balance the capacities of individual groups of cells within a lithium-ion battery pack. Maintaining capacity balance within the battery pack in this manner can significantly extend its cycle life. We explore the physical implementation of this concept … Web28 jan. 2016 · Moreover, the Li-ion battery used in the present study has been verified to have low cell imbalance when 10 cells are connected in series without any cell equalizers, and the charging-discharging energy efficiency of the battery pack has been obtained through hardware experiments.
