As electric vehicles (EVs) reshape the global automotive landscape, the safety of lithium-ion batteries has become a major concern. Thermal runaway, in which battery cells overheat uncontrollably, poses risks such as fires, explosions, and costly recalls.  Raytron, known for its thermal imaging, has developed an AI thermal monitoring system that detects temperature issues in real time throughout the battery's lifespan. This system helps manufacturers, logistics companies, and technicians find and address battery issues before they become major problems, making EVs safer.

Raytron's system identifies the early signs of thermal instability that traditional sensors might miss. Thermal runaway typically starts with minor temperature changes that indicate micro-short circuits, weak connections, or poor cooling. Raytron's system uses infrared to create a visual map of these hotspots, so engineers and technicians can spot problems early. AI algorithms track temperature trends and changes, providing predictive alerts that complement traditional Battery Management Systems (BMS). This protects the cars and users and helps manufacturers trust their battery performance.

Raytron's tech is used at all stages of the battery's life. During research, it helps engineers verify heat transfer, test cooling systems, and test safety systems. In production, the TN220 thermographic cube camera examines individual cells for micro-defects, helping identify potential failure points during charging and discharging cycles. This reduces the risk of bad batteries reaching customers, minimizing recalls and protecting the company's reputation.

Raytron’s AI-enabled thermal imaging technology offers insights into battery performance and efficiency. By looking at heat maps over time, manufacturers see where heat is generated, improve cooling, and improve cell design. This helps them make batteries that store more energy, charge faster, and perform better overall. The AI system learns from new data, improving its predictions and working with new types of batteries. By using infrared imaging, industries across the board can monitor battery health in real time, prevent failures, and improve energy storage. Furthermore, the scalability and flexibility of Raytron's solution make it a crucial technology for the expanding battery ecosystem.
