5 minute swap is not needed for this.

Well, if it degrades to 90% after three years, and let’s extrapolate to 81% after another two to three years, then a battery swap in 5 minutes might be reasonable to do instead of charging once every three to five years or so. I guess it depends on the quality and retained capacity on the batteries being swapped in.

  The vast majority of charging is done at home, though. Five-minute-charging/swapping is basically a gimmick to show off to your friends, and only really sees (questionable) use during that once-a-year road trip. The main value in these technologies is to shut up the "But sometimes I want to drive for 20 hours without being forced to take even a single 30-minute break!" pseudo-argument as to why an EV is "impossible" for their lifestyle. Same with the Lucid Air and its 1000km range: basically zero people truly need it, but it needs to exists in order to drag the last few holdouts into the future.

    When my road trip is in negative temperatures, I appreciate not having to be in the cold for too long. I think the bigger adoption issue is thoughts of scaling the charging stations. If there’s a line of cars at a liquid fuel pump, one can still get fuel in twenty or thirty minutes. If there’s a line of four cars at every charger and every car takes 15 minutes to charge on average, that’s an hour before you can start.

  > Well, if it degrades to 90% after three years, and let’s extrapolate to 81% after another two to three years, then a battery swap in 5 minutes might be reasonable eh? are you saying that something that is done once every 5 years has to be done inside 5 minutes? I strongly disagree. > charging once every three to five years or so Um, that's not how charging works at all.

    That’s not how sentences or quotations work at all.

    That was assuming, based on their recharge count, daily 10% to 98% rapid charging. You’d only see that in a vehicle of this range if it’s being used as like a courier vehicle or moving billboard. Pretty much the actual worst cases.
