Renault Is Sharing Its Proprietary Technology to Rapidly Address EV Fires

      Renault is adopting a Volvo-like approach by offering its safety technology to the automotive industry at no cost. Long ago, Volvo gained recognition for developing the three-point seatbelt and, instead of charging other manufacturers a hefty fee, they made it freely available to enhance safety. Similarly, Renault is taking a commendable step with its electric vehicle "Fireman Access" system, which aids firefighters in extinguishing battery fires significantly more quickly.

      Battery fires in electric vehicles (EVs) can be catastrophic. Research indicates that EVs are less prone to catching fire compared to internal combustion engine vehicles, contrary to what some critics claim, but when they do ignite, the consequences can be severe. Fires resulting from thermal runaway burn at extremely high temperatures and do not require oxygen, making them particularly challenging to extinguish. It often takes a large volume of water and several hours to put out a battery fire, and it can reignite spontaneously, even long after it has been doused. Some fire departments have resorted to submerging ignited EVs in water-filled dumpsters for days to ensure they remain extinguished.

      Renault's patented system is straightforward: an adhesive disc seals a hole in the battery pack. This disc is deliberately designed to be weak enough to break under the pressure of a fire hose, enabling firefighters to inundate the battery compartment with water.

      Renault claims that this technique allows EV fires to be extinguished in as little as a few minutes rather than hours. Consequently, the company states that it reduces water usage by ten times.

      "Innovating to enhance road safety is intrinsic to Renault's identity. We take great pride in the collaboration established with fire services in recent years. Fireman Access exemplifies the potential of combining our manufacturing expertise with the skills of the dedicated individuals who protect us daily," stated Renault Group CEO Luca de Meo in a press release. "Today, I am thrilled to make this innovation available for free because, when it comes to safety, we must eliminate all barriers. This initiative aligns with our commitment in partnership with the United Nations to improve mobility safety worldwide."

      Currently, all Renault, Alpine, and Dacia EVs and plug-in hybrids are equipped with Fireman Access ports. Looking ahead, Renault hopes that more automakers will adopt similar systems, as they seek nothing more than a simple "thank you" and a friendly high five in return for the use of this patent. While it may not have the same impact as the three-point seatbelt, I believe any time a company prioritizes vehicle safety over profit, it deserves a resounding acknowledgment.
