Although electric vehicles have a lower risk of catching fire than internal combustion vehicles, they still pose unique challenges and potential hazards for emergency responders, secondary responders, EV drivers, and the general public.
Letting the battery burn out safely may be possible, but this could take weeks.
Water cooling can slow and stop battery overheating, but it may take a few hours.
Submerge the entire vehicle in water. Could cause re-ignition.
Special lithium extinguishers can be used to suppress the fire. Risk of re-ignition remains.
FIRE ISOLATOR is a concept for isolating and fighting EV car fires based on best practices and live testing. In general, there is not one single solution to extinguish or control EV car fires, as all firefighters who have dealt with these types of car fires will be able to confirm. Effectively isolating and fighting EV car fires takes several different methods because of the lithium-ion batteries on board of EV cars. The EV car will need to end up submerged in water in a container, but with the FIRE ISOLATOR concept, a lot can be done beforehand to minimize the damage. Fighting EV car fires with the Fire Isolator concept has been thoroughly tested and proven effective.
FIRE ISOLATOR can be summarized by ‘winning as much time as possible to limit the collateral damage’. The tactics needed for doing this were tested successfully on combustion engine cars and EV cars in 2021 in Denmark by professional firefighters and experts from all over Europe.
