As global electric vehicle (EV) adoption accelerates, lithium-ion battery thermal runaway has become one of the industry’s most critical safety challenges. In response, Raytron, a global leader in infrared thermal imaging, has introduced an advanced AI-powered thermal monitoring solution that provides real-time, high-precision detection of temperature anomalies throughout the entire lithium-ion battery lifecycle—helping prevent catastrophic failures before they occur.
Thermal imaging is essential because thermal runaway begins with subtle, early-stage temperature changes that are invisible to traditional sensors. Raytron’s infrared technology enables non-contact, real-time temperature visualization to identify micro-hotspots—the earliest signs of internal shorts, poor connections, or cooling issues—long before they escalate into fires. Enhanced by AI algorithms, the system analyzes temperature rate-of-rise and thermal patterns to deliver predictive safety warnings, extending the capabilities of traditional Battery Management Systems (BMS).
Across the battery lifecycle, Raytron’s technology strengthens safety at every stage. In R&D, thermal cameras validate heat propagation and containment performance during stress tests. In production, the TN220 thermographic cube camera identifies cells with micro-defects during charge and discharge cycles. In logistics, 24/7 thermal scanners detect hotspots in storage areas, while in after-sales service, handheld thermography tools help technicians locate and address thermal faults early—preventing small issues from becoming dangerous events.
