Application
TI's integrated passive balancing evaluation module is designed to monitor and balance battery cells to
ensure safe and reliable operation. Energy storage systems can be severely impacted by improper
management of the charge and discharge cycles of the employed battery cells. Over time, charge and
discharge cycling causes individual variations in the voltage, charge capacity and internal impedance of
the battery pack cells, leading to reduced effective capacity and lower efficiency.
