“Electric cars are already going 450-500 miles and new batteries coming out fully charge in 5 minutes or less.”

Let me guess, in “development”?

And tell me, where do you find a place to deliver .5 MWH (rough BTU equivalent of 15 gal of gasoline) in 5 minutes?

That’s 12,000 amps at 480v.

Got any links to share this miracle of engineering with us?

Posting this again as, apparently, I need to.

People have no concept of what power flow requirements are needed to fill up multiple batteries at the rate necessary to equal the driving range and fill time of a typical gas powered car.

15 gallons of gas is equivalent to about half (.495) a MWH. That means to fill an equivalent battery in 15 minutes (a very long fill up time at best) you’d need to pump in energy at a rate of 2 MW per car.

For a small 8 pump filling station that’s a capacity of 16 MW. We’d need that much electrical transmission capacity, or more, going to nearly every filling station in the country.

The country’s entire electrical distribution system would need to be replaced from the ground up with one capable of orders of magnitude more power generation and transmission.

Replaced.

It is flat out not possible to upgrade the current system to meet that need.

Not going to happen.
