So that truck stop has ten bays and each one will be occupied for a full hour to recharge the truck.
That doesn’t pencil in, either. I doubt a truck will reach a useful charge in an hour, but that is at least four times longer than the time needed to fill the diesel tanks and hit the road again. So, to keep the same truck throughput through the truck stop you need 40 chargers, not 10. The power requirement will be lot higher than your quick calc shows.
Recharge times are (rapidly) decreasing.
Very quickly.
There's other factors that have to be considered.
A typical tractor-trailer weighs around 80,000 pounds when fully loaded and approx. 35,000 when empty.
The size and weight of a battery pack is going to be massive considering the battery pack of a Hummer is around 2,800 pounds.
Generally, most over the road rigs will have either two 150 gal tanks or two 200 gal. tanks. That gives them a range from 600 to 800 miles. There's no way a tractor EV is going to even come close to that mileage.
Additionally, truckers can only drive 11 hours in a 24 hour period, which is around 715 miles at an average 65 MPH. There's no way they are going to want to waste that drive time at a truck stop waiting for their batteries to charge multiple times.
It should also be noted that a long haul driver will log between 100,000 - 110,000 miles a year so it’s unknown how long the batteries on a semi will last at that rate.
