No long-haul electric truck technology exists.
Daimler Truck, one of the world’s largest commercial vehicle manufacturers, has unveiled its first heavy-duty, battery-electric truck – the Mercedes-Benz eActros LongHaul – with a new e-axle and a range of 500kms.
Electric truck maker Janus has debuted the first battery-powered prime mover in Australia and has plans to set up battery swap stations up and down the eastern seaboard within months. .. a first taste of the company’s plans to electrify long haul truck fleets using only batteries.
500 kms w/out having to stop is a long leg.
Being able to stop and swap out | replace batteries in the same time as a refueling | load | unload is indeed "a long haul technology" as it enables long haul trucking.
The speed limit for this vehicle will be either 80km/h or 100km/h, I'm not sure how they decide, but with some good logistics for a rapid charge part-way through that's not far off.
