Hyundai Mobis Unveils EV Battery Fire Suppression Technology

The newly developed system targets thermal runaway at its source, integrating advanced hardware and software to meet rising global safety standards.

Hyundai Mobis has announced a patented EV battery fire suppression system that automatically discharges a suppressant to prevent the spread of fire.
The innovation focuses on halting thermal runaway, a dangerous process of uncontrollable overheating in battery cells.
The system integrates a Battery Management System, extinguishing devices, and specialized battery cases equipped with internal sensors to detect and respond to abnormalities.
This first-of-its-kind technology aligns with stricter safety regulations in markets like Europe, China, and India, which require delays or prevention of thermal transfer during battery fires.
While the company has filed domestic and international patents for the system, no timeline has been disclosed for its commercial implementation.
