Let’s just take one of Tesla’s electric semis as an example. The truck supposedly has a battery capacity of 900 kWH. So to fully recharge it from 0 in one hour it would require a charger with an output of 900 kW. So let’s say we have a truck stop with 10 charging stations for electric semis. And let’s assume for planning purposes that at some point all 10 will be in use at the same time. That would be an electrical demand of 9,000 kW or 9 MW. That my friends is the same as a small-medium size factory. Multiply that scenario hundreds of times and you can see the potential problem. And that’s just for semis.

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.

I remember reading the same thing in 1979 about this in the January/February 1980 issue of Elementary Electronics in the Q and A column, "Ask Hank, He Knows." The answer is muich the same as you posted here:

What an Outlet

My friend's father invested in a new electric car that he says "Detroit" is trying to suppress. It's a small car that can range up to 150 miles from home and return, and recharge in five minutes due to its very unique battery system. Isn't it a crime how new energy saving systems are being shot down?

-L.A., Westland, WI

If all that you say about the car is true, then think of this: assume the car's motor is rated at 40 horse power -remember, you said a small car. Assume it is run at 50 mph for the full range of the car (300 miles.) In six hours of driving, the car uses up 11,040 watt hours of energy. To replace their energy in five minutes would require an AC oulet at your home that can deliver about 92 ampere hours or approximately 1100 am- peres for 5 minutes. Just imagine the size of your house wiring. Remember, when charging a battery, you must replace every kilowatt hour of energy that was used. Also, I did not get into the matter of efficiency and heat in the battery system. A very high current charge produces excessive heat -the battery may even glow! That's not too good for the battery. Look again into the facts, you may have your information jumbled.

“”So let’s say we have a truck stop with 10 charging stations for electric semis””

Many companies and municipalities have converted entire divisions and fleets to Natural Gas (NG). UPS, FEDEX, etc. In 2016 FedEx established several hubs with NG as the fuel. NG was touted as the ‘clean’ hydrocarbon. Remember all those commercials ‘cooking with gas?’ We still today export large amounts of NG overseas. President Trump proved that inexpensive, abundant energy equals more freedom, and America was enjoying that freedom. Yet another reason they had to steal the election and limit our energy. DemocRATS cannot stand free people, free enterprise, and all the progress and joy that results.
