This trailer saves 7000l of diesel per year. Assuming 40l/100km, with this trailer you can go ~17.000 km more, which is 11-17% more, for the same fuel cost. Or ~12-15k EUR in fuel savings per year (assuming 1.8EUR/l).

With 13+ years ROI (electricity is not free) is this really beneficial?

Maybe you shouldn’t throw out your new trailer, but it looks like a good deal for expanding a fleet.

Remember that all signs point towards more CO2 fees and higher gas prices in the coming years

Regenerative and solar electricity is free, and regen braking additionally saves wear and tear on brake pads.

The real benefit I think is when stuff like tax codes, carbon credits and government subsidies come into play and ROI goes down significantly.

Or when the next war hits and diesel actually hits and bypasses the 2.50€/l mark.

Cool, but I don’t see the real benefit. Electronic trucks already work quite well, start at around 150k (vs. 150k for a retrofitted e trailer), and are afaik mostly limited by the charging infrastructure. If you now add a an electronic trailer to your diesel truck, you now also have to care about charging. Yes, in Europe the legally required rest periods can already be used for efficient charging, but this is not an…

Charging time. A truck/driver doesnt remain stopped. It drops a trailer and picks up another. And a truck needs charging on the open road where there just are not any charging stations. But a trailer remains parked at a loading bay for hours, a commercial facility where installing chargers makes sense. A trailer therefore has more oppertunity to charge than a truck. And if a company wanted to, parking a trailer to le…

But that's the thing: you already have to pay a driver to sit around!

In Europe there's (simplified) a mandatory 45-minute rest break after 4.5 hours of driving. Similarly, there's a mandatory 11-hour rest period after the daily maximum of 10 hours of driving. And it is very strictly enforced, with every commercial truck having been equipped with a sealed and certified data logger, plenty of random checks by traffic police, and heavy fines for any kind of violation.

If the truck is already sitting idle ~half of the time due to driver rest requirements, why not take that opportunity to charge it as well? Similarly, if you are building the usual highway-side rest stop with truck parking, a petrol station, and a restaurant, why not add a charging station as well? It can even do double-duty as rapid car charger!

Those are unreliable and vary at the whim of the government and their need to fill a hole in the budget. The only reliable factor here is a subsidy on the purchase price for the trailer as that can not be withdrawn after a year. Carbon credits will disappear as soon as a significant part of transport has been electrified, electricity prices are still rising, tax exemptions are temporary at best.

I'm not seeing any sign of CO2 fees increasing in the USA. If anything, they'll be federally outlawed.

In Europe (at least in Germany) we already have a lack of truck parking spots along many routes. And that's with parking spots that are just a bit of Asphalt and maybe a portapotty, or big asphalt parking lots attached to a rest stop

If we had enough chargers that any trucker could pull into a truck stop at their prescribed rest period and find a free charger, electrifying trucks would indeed be a no-brainer. But in the world we currently live in we don't have enough chargers to make that reliable. We barely have enough non-electified parking spots, and in your world they would all have to be electrified as well. It's a mix of a chicken-and-egg problem on the commercial side and a lack of will on the government side

But there is never a lack of will from the government to try all kinds of pilot programs that look cool but are mostly caused by the need to somehow sidestep the lack of sufficient charging infrastructure

At least from the truckers I watch on YouTube from Germany, there is already a shortage of rest stops for trucks. Sometimes you can see them even in the entrance of the rest stops, parked in a dangerous spot. If they all have to charge, then that becomes a problem, because they can’t find a space even „creatively“.

Not saying that electric trucks are bad, just one more problem to solve
