Automotive battery management system (BMS)

Automotive Battery Management Systems (BMS) must be able to meet critical features such as voltage, temperature and current monitoring, battery state of charge (SoC) and cell balancing of lithium-ion (Li-ion) batteries.

What are the main functions of a BMS?

What are the main functions of a BMS?

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).
