Overview

• 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.
