As electric vehicles (EVs) continue to expand across global markets, from public transport and construction to mining and agriculture, the fire safety challenges they bring are evolving just as quickly.
For fire safety professionals, adapting to this high-voltage reality means rethinking traditional suppression systems and adopting technologies designed for today’s mobility landscape.
At Fogmaker International AB, we have developed fire suppression solutions for complex, enclosed engine environments since 1995. As battery electric (BEVs) and hybrid powertrains become the new normal, our work is more important than ever.
Understanding fire risks in electric vehicles
While EVs are generally safe, their fire risk profile differs significantly from that of combustion engines. Fires in electric vehicles are often caused by collisions or fires that start in a more traditional place than the battery pack, but once the batteries are affected, temperatures can rise rapidly, ignite adjacent cells and release toxic gases. Research has shown that many of the fires in BEVs do not originate or even have a link to the battery itself, but it is also known that the severity when a fire gets to the battery is high.
Battery fires present several challenges. They can reignite long after appearing extinguished, are difficult to access because battery packs are well protected and are located in compact spaces within the vehicle. These characteristics demand suppression systems that activate automatically, respond rapidly and provide strong cooling performance.
In addition, emergency responders must consider the extended duration of EV battery incidents. Fires can burn for longer periods and may require sustained cooling to prevent thermal runaway from spreading to neighbouring cells within the battery pack.
Why high-pressure water-based mist works
High-pressure water mist systems provide an effective solution for enclosed vehicle environments. Fogmaker’s system produces micro-droplets with a large, combined surface area that absorbs heat quickly, chokes the fire, and cools the affected area.
The technology offers several important advantages:
- Rapid flame knockdown
- Efficient cooling to reduce the risk of re-ignition
- Minimal water consumption
- Safe operation around sensitive electronics
- Automatic activation independent of vehicle power supply
