As newenergy battery energy density continues to break through and their applicationscenarios continue to expand, infrared thermal imaging testing technology isbecoming a key safeguard for battery safety. This technology captures infraredradiation emitted by an object itself, converting the temperature distributionduring battery operation into intuitive thermal images. This provides a preciseprediction and monitoring solution for potential thermal runaway risks withinthe battery.
TechnicalPrinciple
Infraredthermal imaging testing uses infrared detectors to receive infrared radiationfrom various parts of the battery. Based on the differences in radiation energybetween different temperature zones, it generates a high-resolution, real-timethermal distribution image through signal processing and image reconstruction.Its core advantage is that it can penetrate the battery casing without touchingthe battery itself, clearly revealing localized temperature anomalies caused byhidden faults such as tab solder joints, diaphragm damage, and internal shortcircuits. With a detection resolution of up to 0.01°C, even the slightestprecursor to thermal runaway can be detected promptly.
QualityAdvantages
•Non-contact testing avoids damage to the battery structure and performance, andis compatible with battery testing requirements for various packaging formats.
•Real-time dynamic monitoring tracks temperature changes throughout thebattery's charge-discharge cycle, high- and low-temperature cycling, and otheroperating conditions, accurately locating fault points.
•Supports batch automated testing, increasing testing efficiency by over 300%compared to traditional manual temperature measurement, significantly reducinglabor costs.
•Real-time storage and analysis of test data provide data support for batteryproduction process optimization and lifespan assessment.
ApplicationAreas
Thistechnology has become an essential testing method for new energy batteries inareas with high safety standards:
•Electric vehicle power battery packs and energy storage battery systems
•Consumer electronics lithium batteries (such as mobile phone and laptopbatteries)
•Batteries for special environments (such as aerospace and batteries for extremeclimates)
•Safety testing during battery recycling and reuse
As newenergy batteries develop towards higher capacity and faster charging,traditional testing methods are no longer able to address the complex safetyrisks. Infrared thermal imaging testing not only solves the current pain pointof hidden battery faults being difficult to detect, but also promotes thetransformation of battery manufacturing from "passive after-sales" to"active prevention" through real-time data feedback, building a solidline of defense for the safe development of the new energy industry.
