So far as we will inform, America has its first pure battery-electric fire truck, now part of the Mesa Hearth and Medical Division Station 221 in Mesa, Arizona. Los Angeles took delivery of a European-style electrical fireplace truck in Could 2022 constructed by Austrian firm Rosenbauer and known as the RTX. The L.A. truck, nonetheless, is a range-extender EV, housing a 3.0-liter BMW inline-six with 300 horsepower to maintain the 2 Volvo Penta batteries topped as much as their 132-kWh mixed capability. Mesa’s new E-One Vector fireplace truck is powered solely by a 327-kWh battery (316 kWh usable). What’s extra, it was designed within the American fashion and in-built Florida by Emergency One, which focuses on building of all method of firefighting autos and equipment.
The large pack powers a 400-kW electrical motor (536 horsepower) that in flip powers both the rear axle or the pump system. When working the pump, the motor can rapidly drain the truck’s 530-gallon onboard water and foam tank. When hooked to a water provide, the pumper can spray a most of 1,250 gallons per minute, or run 750 gallons per minute by way of 4 hoses for 4 hours on a full cost. E-One says that is “the longest electrical pumping length in business.” For fireplace departments that request a range-extender engine, the utmost circulation price rises to 1,500 gallons per minute and lasts so long as the gasoline does.
Again on the station, outfitted with a DC quick charger, the Vector’s 120-kW most fast-charge price can refill its battery in about 3.5 hours.
L.A.’s Rosenbauer RTX truck value the town $1.2 million. Mesa authorities did not expose a worth for the E-One Vector, solely noting that funding got here from a voter-approved bond subject from 2018 and the town’s basic fund. The $1.2M is not out of line with present costs for conventional diesel-powered pumpers due to exceptional inflation over the previous three years, even wilder than that for the automotive market. A fire department in Sudbury, Ontario, Canada, bought three pumper vehicles in 2020 for $788,010 CAD ($590K U.S.) per truck. In 2022 and 2023, the town council accredited shopping for two extra pumper vehicles for a mixed worth of $1.7M CAD ($1.2M USD), accounting for a historic price of three% worth inflation. When the council lastly put out the tenders and obtained them accredited in late 2023, the worth of every truck was $1.46M CAD ($1.1M U.S.). A similar thing happened in Connecticut early final 12 months, the Norwalk Hearth Division asking for $1.35 million mixed for 2 fireplace vehicles in 2022, however needing to pay $1.84 million by the point of buy in 2023, on prime of seeing its ready time for supply go from the standard 9 to 12 months to 2 or three years.
L.A.’s records for its Rosenbauer RTX PHEV present virtually totally electrical operation. Within the preliminary six months of service, the RTX’s pure-electric working got here to 99% of service time for calls, 98.2% of service time when together with all operations and coaching. Estimates for the present 12 months of operation that ends in March determine a minimal of 96% pure electrical operation in all phases of use. Mesa purchased its electrical fireplace truck as a part of efforts to be carbon impartial by 2050, and because the Vector is all-electric, it must be even greater than L.A.’s excessive commonplace when evaluating car emissions.
