Hyundai Mobis Develops Cutting-Edge Technology to Prevent Thermal Runaway in Electric Vehicles

Hyundai Mobis, a leading automotive supplier based in Seoul, Korea, has made groundbreaking advancements in safety technology for electric vehicles. The company has successfully developed a new system that can extinguish fires in battery cells within 5 minutes of ignition, effectively preventing thermal runaway. This innovative technology not only prevents heat transfer to adjacent cells but also marks a significant milestone in next-generation safety measures for the global market.

Preventing Thermal Runaway: A Game-Changing Innovation

The new system designed by Hyundai Mobis goes beyond simply delaying thermal runaway using heat-resistant materials. It focuses on preventing thermal runaway from occurring in the first place, setting a new standard in safety technology for electric vehicles. Major countries such as Europe, China, and India have mandated measures to delay thermal runaway for at least five minutes after ignition, with some tightening regulations to prevent thermal transfer altogether. Hyundai Mobis’ battery system assembly (BSA) with a cell-level fire extinguishing feature is expected to lead the way in global safety technology.

Hyundai Mobis’ Revolutionary Battery System Assembly

The BSA developed by Hyundai Mobis comprises a battery management system (BMS), hardware with a fire extinguishing device and battery case, and software logic for seamless control. Real-time data collected by sensors is analyzed to detect abnormalities in temperature, voltage, and pressure within the battery system. The system then determines the precise location for spraying the extinguishing agent and commands the fire extinguishing device to operate. With a focus on quick and accurate decision-making, Hyundai Mobis’ software features multiple safety devices and a redundant algorithm structure for optimal performance.

The battery system is equipped with a fire extinguishing agent with five times the capacity of a standard home fire extinguisher. This substance boasts excellent cooling, insulation, and permeability properties while being environmentally friendly and safe for human use. Hyundai Mobis has also filed for three patents, including a battery case and fire extinguishing device, showcasing its commitment to ongoing innovation and advancement in safety technology.

A Vision for the Future: Hyundai Mobis’ Commitment to Safety

Park Yong Jun, Vice President of the Battery System R&D Group at Hyundai Mobis, emphasizes the importance of stringent safety standards for battery systems in an evolving market. The company aims to integrate hardware and software to develop advanced battery systems that not only meet but exceed global standards, ensuring the highest level of safety for consumers worldwide.

In addition to its groundbreaking fire extinguishing technology, Hyundai Mobis is also focused on commercializing a new material to prevent battery overheating. The pulsating heat pipe, composed of aluminum alloy and refrigerant, has shown promising results in lowering internal battery temperatures, particularly during rapid charging. This innovative thermal management system is poised to revolutionize heat management in electric vehicles.

Conclusion

Hyundai Mobis’ relentless pursuit of safety and innovation has positioned the company as a leader in the automotive industry. With cutting-edge technologies to prevent thermal runaway and overheat, Hyundai Mobis is setting new standards for safety in electric vehicles. As the global market shifts towards stricter safety regulations, Hyundai Mobis remains committed to developing advanced solutions that prioritize consumer safety and environmental sustainability.
