The only physics-based battery safety system that's FAA-certifiable. 7-9 days of advance warning. No training data. No black boxes.
Current battery monitoring can't predict novel failures. They wait for known signatures — by then, it's too late.
Conventional BMS monitors thresholds. By the time voltage or temperature spikes, thermal runaway is already beginning.
Internal cell damage is invisible to voltage and capacity measurements until catastrophic failure occurs.
Machine learning needs thousands of failure examples. New chemistries and edge cases remain unpredictable.
A single, physics-derived metric that quantifies battery stability in real-time.
Cell-level monitoring, fleet-wide visibility, and FAA-certifiable safety insights — all from one interface.
Real-time SMI for every cell in your pack. Identify weak links before they fail.
Multi-aircraft dispatch authority with go/no-go decisions based on stability margin.
ARP4761 safety assessment, DO-178C compliance, and full audit trails.
Traditional battery monitoring relies on thresholds and machine learning. SEIONICS takes a fundamentally different approach — applying first-principles physics to predict instability before it occurs.
Our proprietary methodology uses fundamental physical laws to calculate a real-time Stability Margin Index (SMI). This deterministic approach requires no training data and works across any battery chemistry.
Unlike black-box ML models, SMI is fully explainable and FAA-certifiable.
SMI is validated across multiple electrochemical domains — proving the underlying physics are fundamental, not curve-fitted.
Battery safety is mission-critical across industries. SMI provides the certainty needed for high-stakes applications.
FAA certification requires physics-based safety monitoring. DO-178C compliant.

SMI integrates directly into cell manufacturing lines — using V, I, and T data you're already collecting to reduce scrap, optimize yield, and trace defects to their root cause.
The GM Bolt recall cost $2 billion. The Hyundai Kona recall cost $900 million. Both traced back to manufacturing defects that passed every quality check on the line.
End-of-line testing catches failures too late — after the cell is built, formed, and aged. Capacity and impedance checks look normal. SOH shows 90%+. Meanwhile, the thermodynamic signature of instability is already there, invisible to conventional metrics.
SMI changes the equation: detect instability during formation cycling — not after weeks of aging — using only the voltage, current, and temperature data your cyclers already produce.
Flag unstable cells during formation cycling — before they move to aging. Reduce end-of-line scrap by catching defects at the source.
Real-time correlation between process parameters and SMI scores. Adjust slurry composition, drying profiles, and formation protocols to maximize yield.
Trace every underperforming cell back to the specific process deviation — loading variance, viscosity drift, temperature excursion — at the parameter level.
Works across NMC-811, NMC-622, NMC-532, NCA, LFP, and LCO. No retraining or recalibration when switching chemistries.
Deterministic, explainable results. No machine learning models to train, no historical failure datasets required. Physics in, physics out.
Plugs into your existing cycler infrastructure. Only requires voltage, current, and temperature — data every manufacturer already collects.
We're partnering with select manufacturers for pilot validation. No new hardware. No lengthy integration. Just better insight from data you already have.
