Management
System / BMS

To meet the complex requirements of application, safety and legal regulations, a battery management system (BMS) is required in almost all cases. The essential task of a BMS is the safety function. In addition, there are optional comfort functions that increase the benefit of the application.

TASkS of a BMS

TASkS of a BMS

Protection of the battery pack against overvoltage, undervoltage, overcurrent and overtemperature

The weakest single cell of the battery pack determines the performance of the entire system. Cell balancing compensates for the different charge levels of the cells that occur during use, thereby improving the performance and service life of the battery pack.

Detection / display of the current capacity of the battery pack

The complexity depends on the type and accuracy of the determination of the state of charge.

Transmission of the characteristic data of the battery pack.

The most common systems are I2C, SMBus, Can, Bluetooth and LIN

Develop your own Bluetooth apps to communicate with your battery.
