And then the EV has to stop and charge for a couple hours. The ICE stops for gas for 10min. Also, check out records like the cross-country NY to LA cannonball run. Cars used there add additional gas tanks to extend range. I'd bet by the time you added enough fuel to a car to equate the weight of an EV battery the range would be significantly higher than that of the EV

  > And then the EV has to stop and charge for a couple hours. Also, it isn't a couple of hours at all. 10% to 90% charge in model 3 takes about 50 minutes using a V2 supercharger (the most ubiquitous one) and about 40 mins using a V3 supercharger. And both take much faster to get to lower percentages, due to the charge rate curve looking more like a log(1/x) graph, with rapid charge rate at the beginning that slows down the more your car is charged.

    An hour is still a hell of a long time to wait for your car to fill up, especially when you're used to going from 5% to 100% in ~10 minutes.

      Again, the charge time is non-linear. You can get from 0 to 50% in just 20 mins. And also, if you are doing a long drive, won't you be stopping for 20-30 mins at least every 200-300 miles (roughly every 3 hours)? Just for bathroom breaks, to get some food, to stand up and stretch, etc.? Imo, this doesn't seem that bad at all. I had the same kind of anxiety over charging too, but since getting an EV and doing multiple cross-state road trips in it and with just tons of daily usage, I found that worry to be unfounded.

        Not at all, I recently completed a road trip from Chicago to Blue Ridge, Georgia with a full car (5 people, including me) in a Hyundai Sonata. It was an 11 hour drive. On the way there we stopped exactly once, and on the way back we stopped twice. If we did this in a Tesla, we would've had to stop far more times, or each stop would have to have been much longer. That's not great.

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.

  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.

  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.

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