Automated Thermal Visibility for Operations and Safety Managers

Battery Energy Storage Systems (BESS) play a critical role in renewable energy infrastructure, but managing large-scale lithium-ion assets introduces a significant operational challenge, identifying thermal issues before they escalate into a fire event. Managing high-energy lithium-ion environments introduces a critical operational challenge, battery storage fire risk.

The challenge isn’t just knowing the risk exists, it’s efficiently monitoring it without draining manual resources, and proving to underwriters that your site is protected. Traditional manual inspections are simply no longer enough to satisfy strict commercial insurance requirements or guarantee total site safety.

At Thermascan, we provide continuous, FLIR-powered thermal monitoring designed specifically for high-risk energy environments. Drawing on our experience protecting Battery Waste & Recycling Facilities and EV Charging Infrastructure, we help identify abnormal heat behaviour at the earliest stage. This automated approach reduces manual inspections helping to protect your people, assets, and operations.

With insurers placing increasing emphasis on fire detection and continuous monitoring within Battery Energy Storage Systems, our solutions provide the thermal visibility and data needed to support compliance, demonstrate effective risk management, and give operators greater confidence in the safety of their sites.

Targeted 24/7 Radiometric Monitoring for Critical Components

Relying on traditional, periodic inspections is labour-intensive and leaves dangerous gaps in visibility. Thermal conditions in battery systems can change in minutes, not months.

Our automated thermal imaging solutions provide seamless 24/7 radiometric monitoring of containers, busbars, inverters and cabling. You gain a constant, live  temperature profile of your entire infrastructure fed directly to your control room or dashboard:

  • Battery Containers & Enclosed Modules: Spot localised hotspot development across high-density lithium-ion cells.

  • Busbars & High-Current Electrical Connections: Identify gradual temperature drift and resistance build-up pre-failure.

  • Inverters & Power Conversion Systems: Monitor uneven heat distribution under normal and peak load conditions in real time.

  • Cabling, Junctions & Distribution Points: Detect unexpected temperature spikes across the wider electrical network before they trigger wider system outages.

Automated Alerts & Grid-Scale Thermal Runaway Prevention

Effective grid-scale thermal runaway prevention relies entirely on timing. Rather than waiting for a manual patrol to spot an anomaly, our continuous thermal systems do the heavy lifting for you.

The moment a component deviates from its baseline temperature, the system acts.

Integrating our continuous monitoring systems with your lithium ion battery fire suppression protocols ensures that suppression mechanisms are triggered accurately without needing a human on-site to make the call.

Our specialised Fire Detection Software can automatically alert operators  the millisecond predefined temperature thresholds are breached, giving safety teams the exact data they need, instantly, and providing a verifiable data trail for your insurers.

Frequently Asked Questions

  • Battery storage fire risks are primarily caused by thermal runaway, electrical faults, or the undetected overheating of critical components like lithium-ion cells, busbars, and power electronics.

  • Thermal runaway is an uncontrollable chain reaction where a rising internal battery temperature triggers rapid, self-sustaining heat generation. If not detected early by thermal monitoring systems, it rapidly spreads to adjacent cells and can result in a catastrophic fire.

  • Advanced 24/7 radiometric monitoring detects microscopic temperature anomalies before smoke or flames appear. This early-warning data can automatically trigger localised lithium-ion battery fire suppression systems, isolating the fault and preventing widespread damage.

  • Because high-load electrical environments change rapidly, periodic manual inspections leave critical visibility gaps. 

    Continuous radiometric monitoring ensures that abnormal heat patterns are identified the moment they develop, allowing operators to intervene before an escalation occurs.
