Hyundai Mobis Introduces Cutting-Edge Fire Safety Technology for Electric Vehicle Batteries

In a significant advancement for electric vehicle (EV) safety, Hyundai Mobis has developed an innovative battery system that includes a built-in fire extinguishing feature. This system is designed to effectively combat the risks associated with battery thermal runaway by deploying a fire extinguishing agent within five minutes of detecting an ignition.

Overview of the New System

On April 14, 2025, Hyundai Mobis announced this groundbreaking technology aimed at enhancing the safety of electric vehicles. The battery system is engineered to not only delay the thermal runaway process but to prevent it from occurring altogether. Regulators in major markets like Europe, China, and India are mandating stricter regulations to curb thermal runaway incidents, making this innovation timely and essential.

The battery system's assembly includes a sophisticated combination of hardware and software, which allows for real-time monitoring and control of the battery's performance. Built with a unique battery management system (BMS), the device employs sensors to continuously assess the temperature, voltage, and internal pressure of the battery system. This data-driven approach enables it to determine the optimal spot for spraying the fire extinguishing agent, swiftly mitigating potential hazards.

Technical Features and Benefits

The technology showcases Hyundai Mobis’ commitment to leading safety advancements. When a battery cell exhibits signs of fire, the extinguishing agent is dispensed automatically. The system’s decision-making software uses reliable algorithms to ensure rapid response to anomalies, significantly increasing the chances of averting a full-blown fire.

One remarkable feature is the volume of the fire extinguishing agent, which is equivalent to five times that of a standard 3.3 kilograms home fire extinguisher. This agent is composed of environmentally friendly materials that ensure safety not only for the vehicle occupants but also for the environment.

Additionally, Hyundai Mobis has applied for three patents concerning various elements of this battery system, including an innovative battery case and the extinguishing device itself, demonstrating the company’s dedication to advancing battery technology.

The Future of Electric Vehicle Safety

Park Yong Jun, Vice President of the Battery System R&D Group at Hyundai Mobis, emphasizes the rising safety standards accompanying the emergence of larger electric vehicles. As the company continues to blend hardware and software advancements, their goal is to not only meet but exceed the global standards for battery safety and efficiency.

In tandem with this development, Hyundai Mobis is making strides in commercializing a new material designed to prevent battery overheating. This cutting-edge solution, known as a pulsating heat pipe, utilizes aluminum alloy and refrigerant to efficiently manage battery temperatures, even during rapid charging scenarios.

Conclusion

As the automotive industry increasingly pivots towards electrification, the introduction of Hyundai Mobis' fire extinguishing battery system marks a pivotal step in addressing safety challenges associated with electric vehicles. This innovative technology promises to safeguard against the risks of thermal runaway while positioning Hyundai Mobis at the forefront of the evolving landscape of automotive safety technology. As this technology transitions from concept to commercialization, the future of electric vehicle safety looks promising.
