German firm launches new tech for firefighters to battle EV fires

One of many largest issues with electrical autos in the present day in an accident is a puncture of the battery cells. When battery cells are punctured, flammable supplies used within the building of contemporary lithium-ion batteries can overheat and catch hearth. It’s very troublesome to place out a battery hearth, and we’ve seen hearth departments take some excessive actions up to now. In some situations, your entire automobile has been positioned into a big tank of water.

An organization referred to as Rosenbauer has launched a brand new piece of kit for firefighters, particularly for combating battery fires in fashionable electrical autos. The tools is an EV-specific hearth extinguisher that has an extinguishing unit and an working unit. The design of the fireplace extinguisher permits firefighters to flood the battery cells with tons of water at a secure distance of about 25 toes away.

The best way the extinguisher works is that an operator would place the extinguisher unit beneath the electrical automobile. The extinguishing mandrel is pushed into the battery and may ship sufficient water to sufficiently cool it and cease the fireplace. Not solely is the system highly effective sufficient to penetrate the powerful metallic defending battery cells, nevertheless it’s additionally powerful sufficient that if the EV is on its aspect or roof, the mandrel can penetrate by means of the inside, high, or truck to chill the battery cells.

Rosenbauer has examined the EV hearth extinguisher on a number of battery designs, together with cells using pouch, prismatic, or spherical building. The system has additionally been examined with hearth departments establishing that it’s suitable with their current firefighting ways and sources. The producer says their extinguishing system is likely one of the finest and most progressive methods to struggle the danger of EV battery fires obtainable. Presently, the EV firefighting system is obtainable to be preordered, with items transport in early 2022.

The producer says that after the system penetrates the battery cells and cools them sufficiently, the automobile is able to be transported. It’s designed in order that water fills the battery housing offering environment friendly cooling to cease thermal runaway and extinguish the fireplace. As well as, the system can function from the conventional stress of the water provide. Which means no extra pumps are required to generate the stress wanted for the gadget to function.

One other huge advantage of the system is that it’s designed so the extinguisher can stay within the battery throughout transport and within the quarantine space. It has been famous a number of occasions up to now, notably throughout crash testing, that generally batteries don’t catch hearth straight away; it might probably take days earlier than the fireplace begins. Nevertheless, with the extinguisher mandril embedded within the battery, it may be simply extinguished once more if the fireplace flares up throughout transport.

The extinguisher system was developed in Germany, however presumably, it’s obtainable globally. With the main push in direction of transferring the lots to electrical autos, severe accidents involving electrical autos will definitely improve. As Chevrolet has seen, defects in battery manufacturing could cause fires with out an accident in any respect. The automaker has seen no less than a dozen fires in its recalled Bolt electrical automobile there have been all attributable to a producing defect on the meeting line at producer LG. The recall to repair these points and change the battery packs in each Bolt produced to date will value LG billions of {dollars}.
