Balancing act
Without battery balancing, the weakest cell in a multicell battery always determines the capacity of the entire system.
However, since individual cells age differently, it is not possible to ensure that all cells have the same capacity, even with a conscientious selection. It needs different approaches.
Lithium-ion batteries, like other battery types, are subject to a process of wear and tear during charging and discharging due to chemical changes.
Battery management systems are responsible for controlling and monitoring the charging and discharging process of high-performance battery packs in autonomous power electronics applications (E-Power) such as electric and hybrid vehicles, robotics or similar. Its main task is to ensure that each individual cell does not exceed or fall short of a defined state of charge (SoC) limit for the application, both during loading and unloading.
