AI Thermal Imaging by Raytron Establishes New Benchmark for EV Battery Thermal Runaway Prevention

MUNICH, Nov. 7, 2025 /PRNewswire/ -- As the global electric vehicle (EV) sector accelerates, lithium-ion battery thermal runaway remains the most urgent safety challenge for the automotive industry. Recent lithium fire incidents underscore the urgent need for non-intrusive, proactive and high-precision monitoring solutions. Raytron, a global leader in infrared thermal imaging, has unveiled its advanced AI-driven thermal imaging technology for monitoring the entire lithium-ion battery lifecycle to prevent catastrophic failures.

Why Thermal Imaging is Essential for Battery Safety?

Thermal runaway is initiated subtle temperature changes, which are the first physical signs of an impending catastrophic failure. However, infrared thermal imaging is a non-contact technology that can provide the necessary real-time, visual temperature data to intervene. At the early signal detection, the thermal imaging instantly identifies minute hotspots, which are early indicators of internal shorts, high resistance connections, or cooling failures, well before they trigger a full-blown lithium battery fire. By integrating AI with thermal camera data, Raytron's solution moves beyond simple temperature thresholds, analyzing temperature rate-of-rise and patterns to provide predictive warnings, effectively boosting the performance of traditional Battery Management Systems (BMS).

How Thermal Imaging Prevents Thermal Runaway Across Stages?

• In R&D, infrared thermography cameras validate BTMS and structural safety by precisely capturing heat propagation during stress tests, allowing engineers to design effective containment against thermal runaway battery spread.
• During Production, Raytron's TN220 thermographic cube camera is used for critical quality control. They screen out high-risk cells with micro-shorts or welding defects by detecting abnormal heat during fast charge/discharge, thereby eliminating latent failure points.
• In Logistics, 24/7 thermal imaging scanners monitor warehouses for spontaneous hot spots, ensuring early intervention to prevent a costly lithium fire.
• Finally, for After-sales Service, handheld thermography cameras enable maintenance crews to quickly locate faulty cells or high-resistance connections, stopping minor heat anomalies from escalating into a full thermal runaway event.
