By enabling the battery pack to work within safe and efficient factors, battery balancing strategies are used to equalize the voltages and the SOC among the cells. Numerous parameters such as the application’s particular needs, budget restrictions, and required efficiency are responsible for selection of ideal balancing 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.
Individual cell voltage stress has been reduced. This study presented a simple battery balancing scheme in which each cell requires only one switch and one inductor winding. Increase the overall reliability and safety of the individual cells. 6.1.
These balancing methods are typically integrated into a BMS, which continuously monitors and manages the state/voltage of each cell, contributing to enhanced battery pack performance, safety, and overall longevity by adding an additional balancing circuit with the battery pack. The overview of cell balancing is shown in Fig. 9.
The battery string consists of n battery cells connected in series. A MOSFET is connected in parallel to each battery cell to realize the balancing function. The model based balancing control module measures the current of the battery string and voltages of all the battery cells. Fig. 1. The schematics of the model based balancing system.
