The Rosenbauer BEST system, meanwhile, has been a purpose-developed to extinguish high-voltage lithium-ion batteries in EVs, with the firefighter using a piercing stinger attached to a hose to penetrate the battery housing and flood the cells, rather than the deck. Direct cooling stops the chemical reaction in the cells and consequent thermal runaway.
“The BEST system has been tested with all known battery types used by European and American manufacturers of passenger cars, trucks, and vans, in capacities of up to 120 kWh,” says Louise Søgaard. “European emergency response services have also tested the system extensively and provided valuable feedback on its practical applications.”
René Kofod, Center Manager at the Slagelse Rescue and Safety Center, Denmark, has spent two years overseeing trials within the ELBAS project (Electric Vehicle Fires at Sea: New Technologies and Methods for Suppression, Containment, and Extinguishing of Battery Car Fires Onboard Ships). He says the Danish Institute of Fire and Security Technology project has confirmed that firefighting tools which deliver water to the battery cell through intermediary spikes or spears are safe, fast and highly effective.
“This type of approach is a new development that you won’t find in the STCW Code,” says René Kofod. “An induction process is certainly necessary to learn about hose connections, pressure set-ups and so on. But the technology is very efficient. The cooling process starts immediately after penetration: sensors in the battery pack show temperatures dropping from 600 degrees to 60 degrees within about 15 minutes, with flow of about 25 liters of water per minute. Other solutions can use 10 or 20 times that amount, which can cause problems on a ship.”
