The EV does not have to stop and charge for a couple of hours. Tesla's V3 superchargers charge at a rate of 1000 miles per hour. Those aren't widespread yet, but the common V2 superchargers provide about 560 miles per hour of charge.

The "miles per hour" charging rate is very misleading. Yes if you wanted to charge a bunch of Teslas to 20% capacity and swap them out after a few minutes each you'd get 1000 "miles charged per hour" But as the battery fills on each car, that rate drops substantially.

If only gas stations marketed their pumps like that. 10 gallons of gas can come out in 1.5 minutes in a Prius resulting in a fill rate of (500 miles range * 40 fill-ups per hour) = 20k mph! We won't consider the time it takes for the next user to get in and put the hose in because Tesla doesn't either.

I am a fan of EV vehicles as well but the long range fill up story is still not good.

You can charge at that full rate to about 80% battery capacity. And none of that matters because 99% of charging is done at home at night. I guarantee the average EV owner spends less time inconvenienced charging their car than the average ICE vehicle owner spends standing at a filthy, toxic gas pump. The only time an EV owner thinks about charging is on a road trip.

I don't know why there is some immune response when pointing out anything negative about an EV at the moment. I just said that the "1000 miles per hour" charge rate is disingenuous at best.

Also it is not true that the supercharger v3 charges at full rate until 80% [1]. The curve drops off quite a bit shortly after 20%. The other points you made, well I never disagreed with that. There are a lot of benefits to an EV, but one clear downside (at the moment) is the long trip charging. This is just a fact and not an indictment about EVs in general

But it does matter here, where we're talking about charging under time constraints...

Your average gas pump seems to pump about 38l/min [0]. Using a rather inefficient car with an usage of 10l/100km, you get an added range of 22800 km/h, or 14250 miles/h. So, still a factor 14 to go.
