In a significant advancement for electric vehicle (EV) safety, Hyundai Mobis has unveiled a next-generation battery system designed to prevent thermal runaway at the individual cell level. This innovative technology aims to extinguish fires within five minutes of ignition, potentially setting a new standard in EV safety protocols.
Traditional EV safety systems often rely on heat-resistant materials to delay thermal events. In contrast, Hyundai Mobis’ approach actively prevents the spread of heat to adjacent cells. The newly developed Battery System Assembly (BSA) integrates a fire extinguishing device, a robust battery case, and an intelligent battery management system (BMS). This combination allows real-time monitoring of battery temperature, voltage, and internal pressure, enabling precise and swift deployment of the extinguishing agent.
The fire suppressant used in the system boasts a capacity five times greater than that of a standard 3.3 kg home extinguisher. It is noted for its excellent cooling, insulation, and eco-friendly properties. Additionally, the software component features redundant logic and multiple safety layers to enhance decision-making during thermal anomalies.
Hyundai Mobis’ innovation aligns with evolving global safety standards, offering a proactive solution to the challenges posed by thermal runaway in EV batteries. By focusing on cell-level intervention, the system aims to mitigate risks before they escalate, enhancing overall vehicle safety.
This development underscores the industry’s commitment to advancing EV safety technologies. As electric vehicles become increasingly prevalent, such innovations are crucial in addressing safety concerns and promoting consumer confidence in EV adoption.
