Battery Pack Cell Balancing
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, the balancing algorithm starts when the battery pack is idle and the difference in the cell state of charge is above a certain predefined value.
