SEOUL, April 14 (Korea Bizwire) — Hyundai Mobis Co. said Monday it has developed a new electric vehicle (EV) battery safety technology that automatically discharges fire suppressant in the event of a battery cell ignition to prevent fires from spreading to adjacent cells.
The battery technology uses heat-resistant materials and includes a fire suppression device integrated with the battery case. Hyundai Mobis said it has filed domestic and international patents for the technology.
Hyundai Mobis, an auto parts unit of Hyundai Motor Group, said the technology allows the prevention of thermal runaway, a term referring to the process of uncontrollable rapid overheating, at the source, going beyond merely delaying the spread of heat and flames.
The company said the technology is considered a first-of-its-kind innovation that has not yet been commercialized anywhere globally.
“As more large EVs with improved driving range appear, the safety standards for battery systems are becoming more stringent,” said Park Yong-jun, vice president of Hyundai Mobis’ battery system research division. “We will integrate hardware and software to develop advanced battery systems that meet and exceed global standards, and introduce them to the global market.”
