I want one!
Hi All, 500 mile range loaded to 80,000 pounds. 30 minutes to recharge to 400 mile range. It may be self driving, too. https://www.greencarreports.com/news/1113863_tesla-semi-500-mile-range-lowe...

Let's assume 500 HP.
1 HP =746 watts, 500x 746= 373,000 watts. At 1000v that's about 373 amps. You'd certainly have to run some pretty high voltage to keep the cable size down. Diesel/electric locomotives do it.
Now, that's PEAK performance, so I suppose it would be less than that most of the time.
They are saying 2 kwhr per mile, or about 150 HP at cruise on flat ground at 60 mph, which is about right with good aerodynamics.
That means the 500 mile range semi has a 1000 kwhr battery. Thats right 1 megawatt hour! Thats ten model S batteries.
Model S batteries are 1200 lbs, so your looking at at least a 10,000 lbs battery.
Tesla says their current battery cost is under $190 per kwhr, so at least $180,000 cost for the battery.
Their not yet deployed megacharger can charge 400 miles in 30 minutes, that means its 1600 kw, imagine a station of 10 of them pulling 16 megawatts, like the power draw of a small city!
You could charge it in 80 hours at full blast on a 50 amp campground service, they probably wouldn't like that.
