TK-UNDERSHIELD is an AI-powered fire prevention system specifically designed for electric vehicles. It integrates multiple sensing technologies—including thermal, gas, and visual data—processed through real-time AI algorithms to detect early signs of battery-related fire risks. Unlike conventional systems that rely on a single sensor input, TK-UNDERSHIELD applies cross-validation between diverse data sources to minimize false alarms and ensure accurate detection. Once a fire risk is identified, the system autonomously activates a high-pressure under-vehicle sprinkler to suppress the fire at its origin. Continuous water dispersion and thermal suppression prevent flame escalation and secondary damage. The entire system is integrated with a remote control platform for autonomous operation and real-time alerts. Because of its compact design and simple installation requirements, it is deployable in a wide range of infrastructure environments—from advanced markets to developing regions—making it a scalable, life-saving solution for global EV fire safety infrastructure.
