Effective Cell Balancing in BMS: Maximizing Battery Health | NAZ …
Without balancing, some cells can become overcharged or discharged more than others. This imbalance can reduce the overall capacity of the battery since the battery management system (BMS) will stop charging if any cell reaches a critical maximum voltage, and stop discharging if any cell reaches critical depleted voltage.
Cell Balancing Techniques and How to Use Them
The worst thing that can happen is thermal runaway. As we know lithium cells are very sensitive to overcharging and over discharging. In a pack of four cells if one cell is 3.5V while the other are 3.2V the charge will charging all the cells together since they are in series and it will charge the 3.5V cell to more than recommended voltage since the …
