Stopyr is our thermal runaway detector for battery energy storage — multi-modal sensors and on-device ML that catch failure signatures before conventional BMS alarms react, with no cloud dependency for the safety decision.

Plugs into existing infrastructure
Conventional BMS monitoring waits for a temperature threshold — but by then, exothermic reactions are already underway.
Electrolyte decomposition vents trace gases before measurable heat. That earlier signal is the intervention window.

Thermal runaway
Threshold alarm trips.
Stopyr watches the rack continuously with low-cost, multi-modal sensors. On-device ML fuses those signals into an early runaway risk score — before a single sensor crosses a conventional threshold.
Multi-modal sensors capture gas, temperature, vibration, and acoustic signatures at the cell and rack — continuously, on-site.
Edge ML fuses those signals on-device to estimate thermal runaway probability — inferring risk that no single direct measurement can confirm alone.
Stopyr alerts reach your BMS, SCADA, or operations team with time to isolate a module — before conventional threshold alarms fire.
Gas trace before temperature
Industrial-grade sensing and edge ML — designed to deploy into existing BESS infrastructure, not replace it.
Trace-level H₂, CO, and VOC monitoring catches electrolyte decomposition gases before temperature thresholds move.
Runaway probability inferred on-device — no cloud round-trip and no connectivity dependency for the safety decision.
Multi-signal fusion and ML classification reduce nuisance trips that erode operator trust in conventional sensors.
Standard outputs plug into existing BMS, SCADA, and site alarm infrastructure — retrofit-ready, no rip-and-replace.
Independent sensing paths continue if one modality degrades — designed for safety-critical industrial environments.
Site-wide and multi-site view across racks, containers, and installations — one pane for distributed BESS fleets.
Stopyr connects to your BMS, site safety systems, and field networks — drop-in install, no rip-and-replace.

Battery storage safety is climate infrastructure — protecting the assets that make renewable grids work. Stopyr's early runaway detection keeps BESS installations bankable, in service, and aligned with Europe's decarbonisation goals.
Protect deployed storage assets. A single thermal runaway can destroy an entire container installation — years of capital, materials, and grid capacity lost in hours.
De-risk grid-scale renewables storage. Safe BESS operation is what makes large-scale energy buffering bankable — storage must scale without becoming the weak link in the transition.
Extend safe operational life. Early gas-signature detection enables planned intervention before catastrophic failure — keeping installations in service, not in the scrap yard.
