Hyundai, a pioneer in automotive innovation, pushes the boundaries of safety with a revolutionary technology designed to prevent battery fires. As electric vehicles gain in popularity, battery safety is becoming a major concern for automakers and consumers alike.
Hyundai is committed to offering forward-thinking solutions to ensure drivers’ peace of mind. This technological breakthrough promises to transform the landscape of the automotive industry by boosting confidence in electric vehicles. Discover how this innovation could redefine safety standards and influence the future of sustainable mobility.
Capacity and characteristics of the extinguishing agent developed by Hyundai
Hyundai has recently unveiled an innovative extinguishing agent, with an extinguishing capacity around five times greater than that of a standard 3.3 kg domestic extinguisher. Designed to prevent battery-related fires, the agent boasts outstanding cooling, insulation and permeability.
In the event of overheating, the system detects anomalies and sprays the agent directly onto the battery, preventing heat spreading to other cells. Environmentally-friendly and safe for humans, this technology meets the increasingly stringent safety standards imposed by various countries to prevent thermal runaway incidents in electric vehicles.
Role of the battery management system and cooling technology
The battery management system plays a crucial role in preventing thermal incidents. Its sensors continuously monitor cell temperature, voltage and pressure. When an anomaly is detected, the integrated software determines the precise location where the extinguishing agent should be applied, thus activating the extinguishing device.
At the same time, Hyundai Mobis has developed an innovative “pulsating heat pipe” technology that enables rapid cell cooling. This approach uses high heat transfer rates to effectively reduce cell temperatures, helping to prevent thermal runaway risks and enhance the safety of electric vehicles.
Energy transition and international regulations
The transition to cleaner energies, such as wind and solar power, has accelerated the electrification of transport, but has also increased the risk of battery-related fires. To counter these dangers, international regulations have been put in place.
In Europe, China and India, a five-minute delay is imposed to delay thermal runaway after cell ignition. Hyundai Mobis, a subsidiary of Hyundai, is committed to developing advanced battery systems that comply with these global standards. The company recently filed three patents for its innovative technology, which integrates hardware and software solutions to effectively prevent thermal runaway in electric vehicles.
