A Single Cell Reaches Thermal Runaway in 12 Seconds
Adjacent cells follow in 90 seconds. Your BESS facility has 14,000 cells across 340 modules. Your daily report says “all systems normal” because nobody checks module-level temperatures.
Four Blind Spots That Let Thermal Events Cascade
Each of these gaps exists on most BESS projects today. Any one of them can turn a single cell anomaly into a facility-level event.
Module-level temperatures hidden in BMS exports nobody reviews daily
Battery management systems generate thousands of temperature readings per day. These exports sit in raw CSV files on a shared drive. Nobody reviews module-level trends because the data volume is overwhelming and there is no dashboard to surface anomalies.
HVAC cooling system PM schedules disconnected from ambient temperature data
Cooling systems are serviced on fixed calendar intervals regardless of how hard they are working. A cooling unit running at 94% capacity during a heat wave gets the same PM schedule as one idling in January. When cooling fails during peak load, cascade risk spikes.
Gas detection sensors tested quarterly — thermal events happen in seconds
NFPA 855 requires gas detection but does not mandate daily verification. Sensors are tested quarterly during scheduled maintenance. A sensor that drifted out of calibration last week will not be discovered for another 11 weeks. Thermal runaway produces gas in seconds.
Fire suppression system maintenance records exist in separate binders
Suppression system inspections are documented by the fire protection contractor in their own system. Your daily report says nothing about suppression readiness. If a module enters thermal runaway today, you cannot confirm from your daily log that suppression was tested this month.
The POD Thermal Safety Stack
Four integrated capabilities that connect BMS data, cooling performance, gas detection, and fire suppression into one daily safety picture.
Module-Level Thermal Dashboard
POD ingests BMS thermal exports and maps every module temperature to a visual dashboard. Anomalies are flagged automatically. Rising baseline temperatures trigger alerts before they reach runaway thresholds.
HVAC-Ambient Correlation Engine
POD cross-references cooling system performance data with ambient temperature readings and module heat output. When cooling capacity drops below the demand curve, maintenance is triggered proactively, not on a calendar.
Gas Detection Compliance Tracker
Daily verification status for every gas detection sensor is tracked in POD. Calibration dates, test results, and sensor health are visible in one view. Overdue sensors are flagged in the morning brief before crews arrive.
Integrated Suppression Readiness
Fire suppression inspection records are captured in the same daily report as thermal data. POD shows suppression system status alongside module temperatures so safety managers can confirm protection is active before every shift.
Watch a Thermal Cascade Unfold Across Your Rack
32 modules in a single container. One module overheats. Adjacent modules begin absorbing heat. Without intervention, the entire rack is at risk. POD detects the first temperature anomaly and triggers alerts before cascade begins.
One Hot Cell Cascades in 12 Seconds — POD Tracks Every Module's Temperature
These KPIs update automatically from BMS exports and daily safety reports. Maintenance scores, thermal trends, and incident rates in one view.
Predictive Maintenance
PODTRIR
Thermal Safety Features Built for BESS
Four capabilities purpose-built for battery energy storage thermal risk management.
Module Temperature Monitor
Every battery module mapped to a thermal dashboard. Color-coded heat status, trend arrows, and threshold alerts — updated daily from BMS exports.
Thermal Cascade Predictor
AI analyzes module temperature patterns across adjacent cells. Rising baseline trends and abnormal heat differentials are flagged before cascade conditions develop.
HVAC-Ambient Correlator
Cooling system output measured against ambient conditions and module heat load. When the gap narrows, maintenance is escalated automatically.
Gas Detection Compliance
Sensor calibration dates, daily test status, and health metrics in a single compliance view. Overdue sensors surface in the morning brief.
“We had a module reach 78 degrees at 2 PM on a Thursday. Our BMS logged it. Nobody saw it until the weekly report. By then three adjacent modules were trending up. POD would have flagged it the same day in the daily report. That is the difference between a data point and a prevention.”
