Fire Suppression for Electric Vehicles

There are many questions and misconceptions about electric vehicles and the potential fire hazard they pose. Note that electric cars, buses, and machines have advanced battery management systems, and the battery chemistry isn’t necessarily the same as in for instance electric bikes or scooters.

On this page, you will find a general discussion about the fire hazards of electric vehicles, why the Fogmaker system is the best choice, and why it is safe for use in electric vehicles. You can also find answers to Frequently Asked Questions here.

The Challenge…

As alternative energy sources become more common, society must get used to new ways of thinking, and managing new risks. Electric Vehicles are not yet standardized, and the designs differ between manufacturers, which means different vehicles have a variety of risk areas in different places. In addition, we don’t know much about how the vehicles will age.

In battery-electric vehicles and machines, both thermal runaway and components can be fire initiators. Research presented at the 2023 FIVE conference shows 50-60% of EV fires never involve the battery itself, and the remaining 40-50% rarely start in the battery.

The main reasons for battery fires in electric vehicles are damage by collision and external fires.

Traditional fire instigators still remain, such as hydraulics, compressors, power steering, and heaters. In addition, EVs have high voltage connectors where corrosion can generate heat, there’s a power inverter and other electronics, and a charging port that will wear with time.

…And Solution

Water-based solutions are considered the best option for lithium-ion fires, because of the cooling effect. Fogmaker works through preventing a fire from reaching the battery, and if a battery should catch fire, the Fogmake system cools it and gives time to evacuate.

Fogmaker has decades of experience in detecting and suppressing fires, and the system will provide the best possible fire protection performance if there is an emergency.

The specially formulated water-based mist protects engines, hydraulic components, and similar at-risk areas. The system is always active, fully automatic, and independent of electricity. It has a great cooling effect and long emptying time, and this prevents re-ignition.

Triple Action

Fogmaker’s fire suppression system handles all three sides of the fire triangle: heat, oxygen, and fuel. The system deploys when the protected area becomes too hot, and sprays a water-based mist that expands and chokes the fire. The mist also cools the area for a long time, at least double compared to other certified systems* which prevents re-ignition.

Always ACtive, Fully Automated, and Independent of Electricity

Research shows water-based mists are the most efficient fire suppressants for electric vehicles. Fogmaker’s mist will not penetrate IP classification IP66 or higher. If the system is activated, clean-up is easy – just rinse well with clean water.

Fogmaker benefits include:

  • Choice between several piston accumulator sizes
  • Easy installation
  • Simplicity – no power supply, the system is independent of position, and it requires minimal space
  • Attacks all three sides of the fire triangle
  • Automatic engine shutdown (optional)
  • Great cooling effect and long emptying time, which prevents re-ignition
  • System monitoring – activity, low pressure, and fire alarm
  • Low life cycle cost – annual inspection, 5-year service, and 10-year service
  • Quality and environmental certifications. IATF-16949
  • Free technical support
  • Global network via certified partners
  • Training through Fogmaker Academy
