(I don't know the answer, but I strongly suspect that regulations are not going to be the driver of the adoption of this tech. Short haul or "hot shot" could be better suited for electric and autonomous. Show me some progress there first and I will buy into some actual disruption. If you want a research assignment, take to the interstate back and forth across a couple of flyover states and stop and see where the trucks actually are.)
The range also lends itself nicely to this. Over the course of a day a trucker would drive a maximum of 855km (they are limited to 90/h), so with a short fast charge during their break the 500 mile version could easily achieve this, then over night it could be charged slower.
Logistics researchers have also been working on this problem for years. You can find paper after paper in the literature.
and you believe either the Trucking companies, the Regulators, or Telsa give a shit what works for Actual Human Truckers....
Telsa is looking ahead to full automation anyway so humans are seen as a inconvenience, and if they make it hard on Truckers that will just give them addition ammo for any concerns regulator have in replacing Truckers with Automation. To these companies The fact that is might be hard for Truckers to find a Charging station that falls in line with Hour of Service rules just proved we need to eliminate the humans
Sure, many electric and autonomous vehicle problems go away if we "simply" re-engineer millions of miles of roads and infrastructure in the country. Now you've got two problems.
Industrial applications already consume much more power than an entire Megacharger site, so supplying the charger with power is an already solved problem. Getting power from the charger the truck is again, a solved problem in the industrial space. I can order an off the shelf industrial connector [1] that does 1000v @ 400A, which means you might need two of them. Truckers already use 2 pumps to fill their truck, so even that is not out of place.
