Smart Energy

The primary role of a BMS is to protect and communicate the status of the battery. The variety of
hazards to be protected from is huge. The safe operating area in green (Figure 1) illustrates the limited
conditions in which a battery can be used. We need to make sure that the battery pack is not used

outside of the design operating range. Complex and safe mechanisms are necessary to keep a battery
in this area and to make it safe for humans. The software portion used in a BMS is a huge part of the
design and needs to be considered in the early project stage. There’s a cost associated with the choice
of IC, architecture, software and battery packs, and without deep knowledge, it’s hard to make the
“best” choice. Don’t hesitate to reach out to Arrow if you need any advice or support.
