How long to charge a heavy duty truck?
What does it cost?
If this place saves on petro chemical fuels, where does the energy come from that generates the power to do the charging?

Well, the article mentions a 1 megawatt rate which is about three times faster than at currently available vehicle charge stations. But that is changing fast. So assuming the 1 megawatt is achievable probably a couple hours for a 1 megawatt pack. Who knows.

Cost at current fast chargers is around 26 cents to 45 cents so multiply that by the pack size and go from there. It costs me 8 bucks to fill up at home, around 20 bucks to fill up at a supercharger. If a truck has a pack 10 times bigger than mine at those rates about 200 bucks.

Where the energy comes from depends on the country, region, province, state etc. In our province it’s from Hydro. Etc etc.

Not an expert. :).

Assuming the battery pack can absorb that much power, Can you get a power feed that is roughly 8500amps (@120v) per charger at a rural truck stop? (Obviously, they would go to higher voltage but it gives people a feel for the amount of power required to feed such a large charger.) A truckstop with say 40 stations, is going going to need something on the order of 40MW power supply (or about 340,000amps @120v).

Keep in mind, unlike a 200-300amp household service, where you almost never actually draw the full rated amps (rarely do you exceed 50%), you can expect to regularly be pulling the full rated amps at charging stations.

To give an idea of how much that is, the average coal power plant in the USA can put out around 650MW. If it provided for nothing else, it could support only 14 truck stops (as described above) and nothing else.

This is also different from the fast charging model for cars where most charging is slow charging done at home over night with only occasional partial charges (to keep the time waiting down) done at fast charging stations. Long haul truckers will be using this as the primary charging method and will most often need to do a full charge.

I can see local delivery trucks being very viable as they cover limited miles and usually wind up at a yard with 10+hrs to recharge overnight. The result being you can overlap between the local building power that is under utilized at night with lower charge rates making it much less difficult to get enough power to make it viable.
Long haul trucking is a different ballgame. They needs lots of power on demand and long charge times cut into times they can be making miles which is what translates to profits.
