Profile »

 

The s-BMS is an exceptionally flexible and cost-effective Battery Management System for automotive, industrial and stationary battery packs ranging from 12VDC up to 1000VDC.
It manages rechargeable lithium batteries of any chemistry and from any battery supplier allowing you maximum battery sourcing freedom.
The system consists of a master board (BMCU) communicating with up to 32 monitoring boards (LMU). Each LMU manages 3–8 cells in series and 2 temperature sensors. The BMCU handles pack level measurements, data logging, application and charger interfaces.
The PC Diagnostic Software provides an intuitive suite of system configuration tools as well as displays for monitoring battery and BMS performance. It allows you to set battery parameters such as limit voltages and temperatures, allowable charge and discharge rates or improve SoC estimation with your own battery model.
To simplify integration CAN frames can be constructed at “Bit-level” to broadcast any of the parameters measured and calculated by the s-BMS. A post-processing module allows you to scale and manipulate values and broadcast them on the CAN bus with no custom development needed. This allows the s-BMS to work as a drop-in replacement for many existing systems.
