REAL-WORLD TEST HAS TESLA SEMI SILENCING CRITICS: ‘I NEVER EXPECTED THE SEMI WOULD ACTUALLY BE ABLE TO GET NUMBERS LIKE THIS’
Many detractors of electric vehicle technology often point to potential range as a notable drawback.

The improvement of charging infrastructure, which allows for the possibility of longer journeys, and enhanced battery technology have made those voices a little quieter in recent years, though.

Now, Tesla’s Semi might further quell some criticisms.

In an independent study conducted by the North American Council for Freight Efficiency (NACFE), a Tesla Semi managed a distance of 1,076 miles over 24 hours.

You know, that boils down to an average of 455 miles per day per vehicle... Not very impressive. Long haul team drivers regularly do over 900 miles a day in diesel trucks, or about double that of what these Teslas are doing.

And the message, that EV technology is advancing at a rapid rate eluded you again. The average trucker goes 500 to 600 miles per day.

He's blinded himself to anything that doesn't toe the party line.

Meanwhile, there's this: https://www.thecooldown.com/green-tech/tesla-model-s-race/
VIDEO SHOWS TESLA MODEL S GO HEAD-TO-HEAD WITH CHEVROLET CORVETTE IN DRAG RACE — SEE WHO GETS LEFT IN THE DUST
Electric vehicles continue to gain ground on traditional gas-powered cars in terms of both sales and performance. A recent video posted to a Tesla fan account on X (formerly known as Twitter) shows a Tesla Model S beating a gas-powered Chevrolet Corvette in a drag race.

Tesla Cars Only (@teslacarsonly) posted the video with no accompanying information about where the race took place, when it took place, or what the distance covered was. It does, however, clearly show the Tesla Model S beating the Chevrolet Corvette with a time of 9.36 seconds to 10.6 seconds.

“TESLA MODEL S SHOWING CHEVROLET CORVETTE DUST IN A DRAG RACE,” the account captioned the video.

About 700 miles per day. That's almost twice the mileage in the contrived EV semi test. Further, a 70,000 lb payload on the EV semi is ILLEGAL. The EV semi is also twice as expensive as a diesel semi. The diesel semi doesn't need recharging, and often has a sleeper cab and everything. The EV semi doesn't. The diesel semi can spend a few minutes refueling for the next leg. The EV semi can't. Requires 350 freakin' kilowatts to charge that sucker in a couple of hours too! That is SEVEN TIMES the entire electrical service in an average modern home!

And how much electrical service would a truck stop have to have to charge the same number of trucks that they normally see every day. :laugh:
 
In the real world taking the charge down to less than 5% as was done here is idiotic on multiple levels.
 
Another thing that you will not hear talked about is the driver economics and driver quality of life declines of the long charge times verses diesel reloading.

Drivers sleep in their cabs or at truck stops. Guess what they could be doing with electric? RECHARGING

This assumes they don't team drive where they are on the road continuously except for refueling stops. A common route for this is the port of LA to the port of Jacksonville FL hauling containers. It's cheaper and faster for team drivers than shipping via the Panama Canal. An EV truck could never match a diesel doing that route with team drivers.

For liability reasons and to not clog chargers and likely because of law I think a driver must be on duty (that is not asleep) during recharging. I am not an expert in this subject but I suspect that is a big negative for both the firm and the drivers.

Its the difference between being able to run a rig 23 hours out of 24 and only about 20 if the tweet in this thread is correct.

They can't charge as many as they can fuel. As always these green nuts are getting ahead of themselves before they have the infrastructure ready. A million trucks would overload the infrastructure

The local truck stop here has seven fuel lanes which are busy most of the day, each truck taking about 10 minutes to refuel.
Since charging an EV takes hours, that means roughly 2hrs * 6 trucks arriving per hour * 7 lanes means 84 trucks would be charging at once, assuming they were all EVs.
At 350kW service per truck (which will charge one in two hours), that would mean 84*350kw or 29.4 megawatts of electrical service would be required. That is at the charging point. To deliver that electricity, about 60MW of electricity will have to generated to compensate for generation, and line, and equipment losses due to waste heat.

Not really practical! :D

The EV semi is not a sleeper. It's only a day cab (designed for local use). Further, truckers run their truck engines to keep the cab warm while they sleep. Turns out that's a pretty efficient use of diesel fuel.
