Balancing batteries in series involves equalizing the voltage and state of charge (SoC) across all cells to maximize performance, battery life, and safety. Proper balancing prevents overcharging or deep discharging of individual cells, distributing energy evenly and avoiding damage. Balancing the cells in a cabinet battery is crucial for ensuring the longevity, efficiency, and safety of the battery system. As a cabinet battery supplier, I've seen firsthand the importance of proper cell balancing. In this blog, I'll share some tips on how to achieve this. The means used to perform cell balancing typically include by-passing some of the cells during charge (and sometimes during discharge) by connecting external loads. Specifically, in applications that need the connection of numerous battery cells in series and parallel configuration, battery balancing is a vital factor of BMSs.
