Electric Vehicle (EV) Fires
Fast Thermal Runaway Control with Minimal Environmental Impact
The Challenge
EV battery fires are driven by thermal runaway—a self-sustaining chemical reaction producing extreme heat, toxic gases, and internal oxygen.
Key risks:
-
Temperatures exceeding 2000°C
-
Toxic and explosive gas release
-
High risk of re-ignition
-
Typical suppression requiring 10,000+ litres of water and 8–24+ hours
This leads to significant environmental damage, mainly from contaminated water and prolonged emissions.
The Environmental Problem
Conventional methods rely on large volumes of water over long durations, resulting in:
-
Heavily contaminated runoff (metals, fluorides, toxins)
-
Extended emission of toxic gases
-
Soil and ecosystem damage requiring remediation
The firefighting process itself often becomes a major environmental burden.
The Flamblocker CF7 Solution
Flamblocker CF7 combines extinguishing and deep cooling, directly targeting thermal runaway:
-
Rapid heat removal from battery cells
-
Continued cooling after application
-
Prevention of re-ignition
-
Strong reduction in water usage
CF7 is:
-
PFAS- and fluorine-free
-
100% biodegradable
- Non-toxic and non-corrosive
Proven Operational Performance
In a full-scale EV test:
-
Thermal runaway stopped in 6.01 minutes
-
Temperature reduced from >2000°C to 20°C
-
No re-ignition observed
-
Water usage: 1,980 litres (incl. 6% CF7)
By comparison, conventional approaches typically require:
-
8–24+ hours
-
10,000+ litres of water
-
Ongoing re-ignition risk
Rapid and complete suppression of thermal runaway in this timeframe remains a major challenge in the industry.
Environmental Impact Reduction
Using CF7 results in:
-
Up to 80% less water usage
-
Up to 80% reduction in emissions
-
Minimal contaminated runoff
-
No environmental impact from the agent itself
The combination of speed and efficiency significantly limits overall ecological damage.
