I know this will sound like sacrilege on EVDL, but does it really make sense to
have battery powered Semitrailer trucks? Isn't it kind of carryingthings a
little too far?
On a practical note, a lot of electricity is met on the grid with natural gas
generators for demand as they can be spun up and down fairly easily toaccount
for variable production and demand.
Wouldn't it make more sense to just power the truck itself on Natural Gas and
skip the power lines/grid/demand/chargestations...etc....
It would also save on 10-20,000 lbs of batteries. not require big investments,
much faster "recharge", and believe it or not, diesels can bet easily
retrofitted to use Natural Gas. (They just aspirate the air intake with nat
gas and still use a small amount of diesel for the "spark". It'sbeen done
in other countries, but for some reason it's just ignored here in the US.
I was very interested in Natural Gas powered vehicles at one time. Largely
ignored in the US.
There are a lot of good reasons (environmentally and economical) to consider
them.

So you foresee a time in the US where the railroads handle the bulk of the
cross-country shipping like they used to? Because that's pretty much the
only way I can see EV semi trucks not being used for over the road
operation. And if full day rate charging is cheaper than the cost of a tank
of fuel (currently $5+ per Imperial Gallon in the US), I suspect most any
shipping company would be fine with it.

Fast charging during the day will be expensive for trucks and thus be
unpopular.
The fast charger operator will take a cut, and the grid operator will
charge peak rates for electricity.
Passenger EV's don't typically use fast chargers, they charge at more
reasonable speeds and rates at home. You want to take a trip, then you are
willing to pay extra to fast charge on the road. Fast charging is like
eating in a restaurant. Most folks see it as a waste of money on a daily
basis and eat at home for far less money.
Economics will shape the industry and will determine how and when trucks
will charge. Unlike passenger cars, trucks are very price sensitive and
will opt for the least expensive option. The available surplus grid
capacity will set the price of electricity, and the trucking industry will
find the most economical electricity price.
EV trucks will seldom be recharged on route at high electricity costs with
the driver being paid to wait. It is not economic as the trucking company
will lose money and it simply will not be done. (Or be done rarely.) EV
trucks will no doubt be used for runs that are within their battery range.
