According to Motoringresearch, Renault Group has announced that its ‘Fireman Access’ system, a patented safety technology designed to mitigate EV battery fire risks, will be made available to all automakers under a free license agreement. This initiative aligns with Renault’s broader commitment to road safety and sustainable mobility, further strengthening its role as a global partner of the United Nations Secretary-General’s Special Envoy for Road Safety. By allowing other automakers to adopt and enhance this technology, Renault aims to foster industry-wide collaboration to improve emergency response times and reduce the risks associated with thermal runaway in lithium-ion batteries.
How the Fireman Access System Works
EV battery fires present a unique challenge to emergency responders due to their prolonged combustion times and potential for reignition. Renault’s Fireman Access system directly addresses these concerns:
- Rapid Extinguishing Mechanism: An adhesive disc is placed over a designated access point near the main battery compartment.
- Direct Water Injection: In the event of a fire, firefighters can use a high-pressure water jet to dislodge the disc and flood the battery pack, cooling it rapidly.
- Minimizing Thermal Runaway Risks: This method significantly reduces the time required to extinguish battery fires from several hours to just minutes.
“Innovating to improve road safety is part of who we are at Renault. By freely offering Fireman Access to the industry, we break down barriers to ensure greater safety in electric mobility.” – Luca de Meo, CEO, Renault Group
Industry-Wide Adoption and Open Collaboration
Under the open license agreement, automakers that adopt Renault’s Fireman Access system must share any improvements they develop. This ensures that continuous innovation in EV fire safety benefits the entire industry.
- Standard Implementation: The technology is already installed on all electric and plug-in hybrid vehicles from Renault, Dacia, and Alpine.
- Global Collaboration: Emergency services across multiple countries have provided positive feedback on the system’s effectiveness in real-world fire scenarios.
Beyond Fireman Access, Renault has pioneered over 2,000 vehicle safety patents since 1970. Another notable innovation is the QRescue Renault system, a QR code-based safety feature that provides first responders instant access to vehicle technical data for efficient emergency intervention.
The Growing Importance of EV Fire Safety Solutions
As EV adoption accelerates, fire safety remains a critical industry challenge. Reports from the National Fire Protection Association (NFPA) indicate that EV battery fires burn hotter, longer, and can reignite even after initial suppression. Industry-wide implementation of fast-response fire mitigation solutions is essential to enhancing public confidence in electric mobility.
Renault’s decision to open-source its Fireman Access technology signals a transformational shift in how automakers address EV safety challenges. By fostering cross-industry collaboration, the initiative sets a new benchmark for emergency response innovation, ultimately making electric mobility safer and more sustainable for the future.
