Battery life: The BMS ensures that all cells within the battery pack are balanced, meaning they have similar voltage levels. Balanced cells operate more efficiently and have a longer lifespan. Types of BMS based on chemistry There are various types of BMS, depending on the application and battery chemistry. Some of the common types include:
Assuming the battery pack will be balanced the first time it is charged and in use. Also, assuming the cells are assembled in series. none, force the cell supplier to deliver cells matched to within +/-0.02V; none, gross balance the pack during first charge once built; preselect and group cells prior to build ; pre-charge/discharge all in-coming cells to a set voltage/SOC; average-balance ...
