Renault opens Fireman Access patent for global EV safety

Renault Group has announced that it will make its patented Fireman Access fire suppression system available for free to the entire automotive industry, allowing other manufacturers to enhance safety measures for electric vehicles. This innovation significantly reduces the time required to extinguish battery fires from several hours to just minutes, while also using ten times less water compared to traditional methods. The system features an adhesive disc that seals a battery casing opening, which is dislodged by a high-pressure water jet during a fire, allowing water to directly reach the battery cells. This initiative, developed in collaboration with fire services, aims to improve road safety and aligns with Renault's commitment to global mobility safety. The decision reflects Renault's dedication to sharing technological advancements within the industry for the benefit of emergency responders and public safety. Seven patents have been filed for this technology, which is already integrated into Renault's electric and plug-in hybrid models.
