New extinguishing system for burning traction batteries in electric vehicles
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.
OPERATION OF THE EXTINGUISHING SYSTEM
Upon assessment of the vehicle fire, it is possible that the battery is not affected. Always assume standard operating procedures of a vehicle fire and
only use the BEST if the battery is affected. If there are clear signs that the battery is affected, the BEST tool should be deployed and used as quickly
as possible.
The following symptoms are indicators of a battery fire:
The extinguishing unit with the piercing nozzle should be placed directly against the battery, where it can be quickly and directly penetrated. If the vehicle needs to be raised to get the unit under, simply use a car jack, spreader, or cribbing for example, then use a pike pole to push it into position.
The unit can also be used inside the cab or from the trunk depending on the location or access to the battery. The extinguishing time depends on the size and architecture of the battery and can be between 10 and 60 minutes.
