Per the EPA, 90% drive at 75,000 pounds or fewer on the road.
Average weight of a class 8 truck is 17,000 pounds and another 4,000 pounds for the powertrain. How much are the batteries going to weight on a Tesla Semi?
The fact that most class 8 trucks need to run at close to 80,000 pounds and truckers need to pay for showers, tells me the industry is running on thin margins,..
I simplistically think of a Semi battery pack is 12 Model 3 packs, that is probably the worst case scenario.
A Model 3 pack weighs about 1,000 pounds, so 12,000 pounds for the battery, worst case scenario.
The last I remember from Elon is Tesla was close to being able to support max weight...
But if we step back a bit, what really matter is the costs per pound per mile, and the time taken to move the freight.
Even with fast charging stop at Megachargers, there is a good chance the Tesla Semi can complete some trips quicker, to do that charging needs to fit inthe drivers scheduled stops, When they are on the road it is going to an ICE semi longer to complete the same trip, especially if it includes a long uphill section.
If think solar power Megacharging at $0.07 even throwing in free showers, this point of showers stems from an online discussion I had with a US trucker. It was a big deal for him, and at the end of the discussion I felt sorry for the poor guy, We all know how driving long miles in a ICE increases fatigue and how all we arrive fresher driving long distance in a EV. Truck drivers worldwide have a demanding job, the squeeze on margins, usually means squeezing them.
At a minimum the Tesla Semi means the driver gets all scheduled stops, completes the trip quicker, and is less tired.
It should still cost less per pound/mile to move the freight.
I can see truck drivers and freight companies readily embracing the Tesla Semi, it is a big step forward on many levels.
