If a truck can go 9 hours on one charge (90 kph * 10 hours = 810 km/~500 miles) then it doesn't need ultra fast charging to be available.  It is usually not legal for a driver to go longer than that (the UK allows 10 hours, but only twice in every week.)

A 500kWh battery can achieve that.  It's a big unit, probably would add about 2-4 tonnes to a vehicle payload.  EV trucks are allowed to weigh up to 46 tonnes in the UK to accommodate this. (Standard limit is 44 tonnes.)

But another option is catenary charging or charging in the mandatory 45 minute rest break at the 4.5 hour point.  (40 minutes at 500kW charging adds almost 60% to the battery pack.)

Unlike cars, trucks have the advantage of central logistics and hubs, with logistics managers planning most of their routes, so they will plan stop times and destinations would have overnight charging available (50kW DC charging would be fine in this case.)

I suggest you take a roadtrip through France and Germany. Then you'll see your assumption is sooo wrong... I do these trips regulary and parking places overcrowded with trucks are very common. And I'm writing parking places, not gas stations! Ratio parking spaces to gas stations is about 5 to 1 so you'd need to install 50-ish fast charging points for trucks at 5 times more locations than there are gas stations. Keep in mind that long haul trucks have ranges up to 2400km intended to do cross-Europe roundtrips on one filling. If a truck driver stops to take a mandatory break (*), the person has to stop working. Not fill the truck or charge it because that counts as work time! Remember trucking is a cut-throat business so transport companies want to keep their people and material rolling as much as possible and not waste the driver's time.

* It is also very common to see truck drivers stop at the side of the road due to have driven the maximum amount of time. Traffic jams due to accidents are unpredictable after all. In Italy I've noticed that it is very common practise for truck drivers to stop along the highways (likely due to lack of parking spaces). How to charge a truck in such a place?

The act of connecting it is working - being present while it charges is not.

Try to convince a judge of that. The law clearly stipulates that any activity that deals with the vehicle counts as work time. Fast charging is something you'd need to monitor and probably free up the spot when the truck is done charging.

Sleeping in it requires operating the lights, cabin heater, entertainment system.. so they're always working, then? Or is there a provision for such in the law? Well then, add one for being present while the vehicle is autonomously charging its battery pack, requiring no human interaction or supervision.

Plug the thing in to charge and walk off to eat a burger, same bloody difference.

Given that cryogenic methane is used already in trucking, I doubt they are going to pay for the convenience.
