Your formally 40k load will now be 60k. That's not insignificant in the discussion of infrastructure problems. There's LOTS of those that will have to be addressed before these things become economically viable.
The max weight of truck and lading can only be 82k. If the truck weighs more, it can haul less weight because the total number does not change.

Yeah they’re way heavier than traditional but I still don’t see how this matters when they’re limited by gross weight. They’ll have a reduced load capacity and the economics will work that out or they won’t.

But painting the current technology as not only viable, but superior, is a lie.
I haven’t heard anyone refer to electric trucks as anything other than “in development.” They certainly aren’t ready for prime time (or even junk time) at this point.
It will be difficult to beat the tried and true long-haul Diesel engine.

Billjammin can correct me but last I heard tesla didn’t reveal the average speed they used to get the 500 mile range. So we don’t really know if they solved it.

They’ve been pretty tight lipped about semi development. I don’t get any info on it yet unfortunately. Oddly I know more about roadster than semi.

It shouldn't be that hard, put an alternator on a belt that can recharge it.

Did they name the route? And did they run 250 miles out and the same route back?
Not difficult to enhance the numbers by choosing an advantageous route.
As an example going from Butte to Missoula is a lot different than the reverse when figuring fuel mileage.

The ones I’ve seen work good for local drayage are nowhere near ready for otr. The roughly have a range of 180 miles loaded and with the 3 battery banks in the cab. To increase the range the manufacturers are looking at putting more banks under the trailer and some are using a hydrogen fuel cell to generate charging power.

With all the bad rap EV towing gets, it got me thinking, how did Tesla solve the towing problem in their semi trucks? Apparently it can go 500 miles while towing 82,000 lbs.
500 miles towing 82,000lbs. This will not happen.

The normal payload for a 53' tractor-trailer is around 43,000 lbs. Unless they engineer a reduced empty weight on the electric version, the payload is probably half of that. So no class 50 to 70 freight, or they are limited to carrying a half empty trailer. Freight is going to get very expensive. They don't have this figured out.

Stop projecting.
You just hate on Musk because he’s the most visible element on something that is trying to offer an alternative to oil and gas.
Dude is on record as saying we need the oil industry to persist until renewables are ready to bridge the gap.

The e-sluths estimate a tractor weight of 27000 based on the assumption that the tweet is referring to folks seeing it haul 11 Jersey barriers.
Just a bit higher than the upper range of conventual tractors.

The days of gas chainsaws and weedeaters and pretty much any other handheld tool we know of that was gas is over. The technology exists, is reliable, and major manufacturers know how to deliver to market.
Maybe for lightweight, non-professional use. Let me know when loggers are felling and bucking with battery powered chainsaws. Arborist top handle saws are the best they have for pros but even then the gas powdered models are used in bigger jobs. Same with weedeaters and blowers, to achieve the performance and longevity of quality 2-stroke equipment there's weight and cost of larger batteries.

So that means in the next 5-10 years, lawnmowers, mini excavators, etc. all go electric- the tech exists today and the envelope (size required to do it and make it reasonable) all works.
Not without massive price reductions. A $5500 EGO zero-turn has neither the capacity or capability of a $3500 Ariens, professional-grade models are probably further away as weight is still a major penalty for such equipment.

A typical Peterbilt 579 weighs; Dry weight: 17,600 lb.

10k, or 5 tons, is a lot more than just a little heavier.
The only tractors that weigh anywhere near 25k are those set up for construction/overweight loads with tag and pusher axles, headache racks, etc. A normal OTR truck weighs about the same as the above Peterbilt.
Just look on the sides of the semis you see on the road. They have the lt weight listed right on the side of some of them.

Seem like they should put a big diesel engine/generator on board to charge the batteries. problem solved.

OTR trucking, pushing barges upriver, basically any kind of sustained hard work is NOT what we should be doing with electric vehicles
I disagree, to an extent. All the big trucks that go back n forth between distribution centers and big box stores could easily be electric.
I don't know what the numbers are but I'm guessing a lot of big trucks on the roads today are making short trips.
The more repetitive and predictable those trips are, the more suitable for electrification they are.

Yes, Fremont to SD mainly via I-5 which means a roughly 10' of net elevation gain. While the severity of grade could impact range more in one direction even with a net zero elevation gain having driven that route numerous times both ways if I had to guess I would say the grades are steeper coming south but that is just gut.

That is around the normal maximum load, the average is well below that as most loads are not near max cargo weight because most cargo cubes out.

I’d assume that’s why Amazon made the purchase of the Volvo FH Electric trucks last year. And it’s also why the same Volvo truck is pretty popular in Europe. Their regulations on daily driving hours and speed limits make it far easier to switch to EV than here.
