EXTINGUISHING SYSTEM FOR EV BATTERIES
The Rosenbauer BEST is an extinguishing system for high-voltage lithium ion
batteries in electric vehicles. Tried and tested since 2018, it is the safest, most
efficient, and fastest extinguishing option on the market to cool batteries and
quickly stop thermal runaways.
With its easy positioning and approach, the operator is a safe 25’ away from
the EV when activating the system. The piercing stinger penetrates the battery
housing, flooding it with water at 8 gallons per minute. A proven reduction in
water, compared to the alternative of a surround and drown method, which
has shown the need of 6,000 – 8,000 gallons of water being required for an
equivalent outcome.
With as little as 500 gallons of water, the Rosenbauer BEST can extinguish a
vehicle battery fire.
Safe. Efficient. Fast
BEST FEATURES & BENEFITS
SAFE
The firefighters only spend a short period of time in the direct vicinity of the electric vehicle to be extinguished. This short time near the vehicle reduces the risk of contamination from the smoke if the battery is evaporating gas.
EFFICIENT
The extinguishing system brings water exactly where it is needed – to cool the cells and modules in the battery housing. Extinguishing the fire is very resource efficient and the spread of smoke gases is minimal.
FAST
Thanks to the 8 milisecond firing speed of the piercing stinger, all currently known and tested battery housings can be quickly penetrated.
COMPATIBLE
Using traditional apparatus compliments, the BEST is propelled by standard SCBA bottles to activate and enter EV batteries.
TESTED UNDER REAL CONDITIONS
During research and development, numerous fire tests were carried out with a large number of battery systems and complete vehicles. The system was tested on all common cell types (round, pouch or prismatic cells) in the platforms of American and European cars and trucks. The batteries tested had a capacity of up to 120 kWh.
PROVEN IN PRACTICE
Factory, professional, and volunteer fire departments have been testing the extinguishing system and are providing important feedback from their experiences.
NORMAL PRESSURE EXTINGUISHING SYSTEM
The extinguishing system simply needs a water supply with a pressure of 60-150 psi.
