Core BMS senses, models and protects each cell individually — so the whole battery lives longer, runs harder and never surprises you.
One distributed architecture scales four orders of magnitude — same telemetry model, same safety logic, top to bottom.
Per-cell voltage, temperature and impedance sampling.
Active balancing and thermal mapping per module.
String protection, contactor control, pre-charge logic.
Pack aggregation, SoX estimation, EMS & cloud uplink.
Anomaly models trained on 40 billion cell-operating hours flag micro-shorts, lithium plating and connection drift long before temperature ever moves.
Per-cell impedance growth and self-discharge anomalies surfaced in real time.
Suspect strings derated or disconnected automatically — output uninterrupted.
Hardware-level protection chain independent of software, certified to ASIL-C.
Adaptive balancing and degradation-aware operating windows stretch usable life by up to 20% — verified across 14.2 GWh in the field.

Core BMS flagged a weak string three weeks before it would have tripped. We swapped it on a planned outage. No event, no headline.
