The main functions of a Battery Management System for electric vehicles are:
- Battery protection in order to prevent operations outside its safe operating area.
- Battery monitoring by estimating the battery pack state of charge (SoC) and state of health (SoH) during charging and discharging.
- Battery optimization thanks to cell balancing that improves the battery life and capacity, thus optimizing the driving range for hybrid (HEV), plug-in (PHEV) and full electric vehicles (BEV).
