MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611111892 A) filed by Motilal Nehru National Institute Of Technology on September 17, 2026, for A Two-Stage Autonomous Thermal Management And Fire Mitigation System For Battery Pack And Method Thereof.
Inventors include Rustam Khan; Swastik Acharya; Praveen Kumar Agarwal; Sachin; Yash Bansal; Shantanu; and Rahul Samota.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention provides a two-stage autonomous thermal management and fire mitigation system (100) for battery pack comprises an upper chamber (107) accommodating the battery pack (105) and featuring venting holes (111) and slots (112), and a lower immersion chamber (101) containing a dielectric fluid. It includes collapsible support plates (104) hingedly mounted upon the lower chamber (101) via hinges (103) and retained by solenoid pins (102). In a first stage, the controller (108) sprays carbon dioxide through nozzles (106) when battery exceeding a temperature threshold by sensing the temperature from temperature sensors (110). In a second stage, upon detecting smoke, the controller (108) triggers the solenoid pins (102) to collapse the plates (104), dropped the battery pack (105) into the fluid in response of detection of fire initiation through smoke sensor (109) to suppress fire and mitigate thermal runaway propagation while improving efficiency and operational lifespan of the battery.
