The French manufacturer's Fireman Access system, installed in all of its current electric and plug-in hybrid models, is designed to allow EV fires to be extinguished in approximately the same time as a fuel-powered combustion engine.
The development is deemed so significant for road safety that Renault is now offering the technology to other brands so they can install it in their electric or hybrid cars.
Other car manufacturers and parts suppliers can now obtain a free licence for this new EV innovation through Renault’s ‘open collaborative platform’.
Part of the agreement states that any licenses that are issued will mean that any upgrades made by other companies have to be made available to all members of the community.
As a partner of the United Nation’s Secretary-General’s Special Envoy for Road Safety, Renault has stated that this is part of its commitment to road safety for drivers all over the world.

How does Fireman Access work?
An adhesive disc is placed over an opening in the vehicle’s traction battery casing, sealing it during normal operation.
Should the vehicle start smoking and catch fire – and the flames reach the car battery – then the forceful water jet from a fire hose dislodges the disc, allowing water to rapidly douse the cells.
According to Renault, this process can extinguish a battery fire in just minutes, compared to several hours. It can also use significantly less water than needed with previous EV fires.
Every Renault Group's electric and plug-in hybrid vehicle now comes with Fireman Access. This includes Renault, Dacia, Alpine, and Mobilize.
Luca de Meo, CEO Renault Group, commented: “Innovating to improve road safety is part of who we are at Renault. We're particularly proud of the partnership developed with the fire services in recent years.
“Fireman Access is a practical demonstration of what can be achieved by combining our expertise as a manufacturer with the skills of the men and women who keep us safe every day.
“Today, I'm delighted to be making this innovation freely available, because when it comes to a subject like safety, we need to break down all the barriers.
“This move is also in keeping with the commitment made alongside the United Nations, to make mobility safer, all over the world.”
What to do in the event of a car fire?
In the event of a car fire, the RAC urges you to follow these steps to stay safe.
Of course, if you are in immediate danger, always prioritise your (and your passengers) safety, and never put yourself at unnecessary risk during a car fire.
Pull over safely
As soon as you notice a fire or smoke coming from the engine, pull over to a safe location away from traffic, buildings, or other vehicles. In urgent cases, pull over immediately and evacuate the area.
Turn off the car engine
Shut off the engine immediately, as this will stop fuelling the fire, and will likely give you more time to get to a safer distance before the fire potentially escalates.
Evacuate the vehicle
Get out of the car as quickly and safely as possible, and make sure all passengers are out too. Ensure you are at a safe distance from the vehicle before taking anymore steps. If you have a chance, put your hazard warning lights on and open the bonnet before leaving the vehicle.
Call the emergency services
Dial emergency services on 999 to report the fire. A fire engine (and potentially police and an ambulance) should arrive as soon as possible. If you have left your mobile phone in the car, leave it there and ask another person or local shop to call.
Do not return to the vehicle for any reason
Car fires are very serious and should be left to the professionals to deal with. However, if it is a small fire, and you are confident in dealing with it, then use a fire extinguisher (if you have one). If it doesn’t have the desired effect, then follow the previous steps.
