Rosenbauer develops a dedicated EV fire suppression system
EV switches will require a lot of EV-specific solutions, one of the most important being how to come up with the battery Fire. Via RideApart, Shirt Fire service company Rosenbauer, the same one that gave the United States its first electric fire truck, has developed a remotely operated fire suppression system for lithium-ion batteries that injects water directly into the battery housing. Electric vehicles are less likely to catch fire than an ICE car, but the chemicals in the battery can cause hotter electrical fires, because of the physical nature of the housing, can be renewed. After a Tesla caught fire in Houston in April of this year, Houston firefighters needed 28,000 gallons of water to put out the fire after it flared up twice. NBC News report that a typical ICE fire can be extinguished with about 300 gallons.
The Rosenbauer apparatus has two components, a fire-fighting unit and an operating unit, which are interconnected by means of a water hose. Firefighters need to get the fire extinguisher between the battery and the road surface if the EV is still on its wheels, or attach it to the outside or inside of the vehicle near the battery if the EV is on its side or roof. Firefighters can then operate the unit from a distance of about 25 feet. At their behest, the fire department drove a mandrel with a pointed tip that pierced the battery with a force of several tons, then passed water through the spike so that it flooded the battery. The device can be attached to the battery during shipping, so as long as there is still a water supply, more water can be pushed into the battery in the event of a recharge.
Rosenbauer says they have tested the system with factory, professional and volunteer fire authorities in Europe, and on different battery designs with desired results and integration with departmental tactics. current division. We look forward to seeing it in action; in the image, a fireman puts the mandrel set under a tram, we want to know how the mandrel assembly is placed under or on a car that has caught on fire. The system is available to order now, with deliveries starting next year.
