You cannot do that, because there will never be that many charging places around. Never. The situation is so bad now that there are barely enough places for trucks to get parking spots, let alone parking spots with electric charges. I'm talking about Europe, my brother is a truck driver (right now is on a ride to Morocco, he picked something up with his truck from Hungary), I know those stories about parking spots from him.
Your cargo may be reduced but your fuel costs will also be reduced. It’s quite a complicated calculation.
Are you hauling sand? Then you probably can’t spare a single kg of cargo limit. Doing LTL work? Then maybe you’re not totally filled anyways. It really depends. If you’re fine with a 35 ton limit you might be able to make good money with the fuel savings.
Assuming some amount of tesla over-hyping there, Tellus is doing 600kW chargers: https://chargedevs.com/features/inside-tellus-powers-600-kw-...
So _if_ your route had those, you could charge in somewhere around 1.25h. Not enough for break time, but you can imagine starting with, say, a 1.1MWh battery with one +500kWH boost mid-day being enough to get you to an overnight full recharge. Lots of "ifs" there, since you might not always be able to get full charge rate from the charger, might not time things perfectly, etc., but it doesn't seem completely out of scope for a few years from now.
(And who knows, perhaps tesla will come through with those megachargers. Seems more likely than, say, building an autonomous humanoid robot.)
