What is battery management system?

The electric vehicle battery management system (BMS) is an important coupling of onboard power batteries and electric cars.

What's the battery management system? its main features include physical parameters real-time monitoring of battery, battery state estimation, online diagnosis, early warning, charge, discharge and charge control, balance and thermal management, etc.

Secondary batteries have the following shortcomings, such as small storage energy, short life, series, and parallel use problems, use safety, difficult battery estimation, etc. The performance of batteries is very complex, and the characteristics of different types of batteries vary greatly. The battery management system (BMS) is mainly used to improve the utilization rate of batteries, prevent overcharging and over-discharging of batteries, prolong the service life of batteries, and monitor the status of batteries. As battery management systems evolve, other features will be added.
