> “5-10 minutes every two hours” … lol, that’s good when you’re going from LA to San Diego. If I had to stop every two hours on a road trip I’d get a train ticket, it would feel a lot faster.

Sorry, now you're spewing nonsense. LA to SD does not require charging at all.

I did more than 120000 miles of road trips in my EVs across the US and Canada, even before they were fully covered with charging networks. So I know a thing or two about that.

A good way to think about charging is not in kilowatts but in miles per hour. Tesla Model 3 peak charging rate is 1000 miles per hour, and the average on 10-80% is around 600 mph. The state-of-the-art Chinese cars can charge at 3000 miles per hour and more than 1200 mph on average.

So if you want to do a 500-mile road trip (~8 hours of driving), that's about 45 minutes of charging time for a Tesla and less than 30 minutes for modern Chinese cars.

But wait, there's more! For a 500-mile road trip, you will have at least 200 initial miles covered by your home charging or if you stay overnight in a hotel with a charging station. So that's even less time spent charging.

And yeah, people usually prefer to do more frequent charges rather than drawing the battery down to 10% to alleviate the range anxiety and just as a safety buffer.

You can’t just assume every time you go somewhere your battery is fully charged.

I mean, you can, because you are clearly emotionally tied into your purchase. But I can’t as an engineer.

  • I can, because I charge it every night. Also, I have never once engaged in a long road trip that I did not know about at least a few hours in advance.

    I think you should not get an EV. But I like mine.

  • I made plenty of spontaneous trips. But even then I just need to pop into my garage, plug in the car, and it'll likely be close to 100% charged within 1-2 hours. Just enough time for me to get breakfast and read the morning YC news.

    And even if you totally forget about charging and you really need to go, that's just an additional ~20 minutes or so. You don't even need to plan the route anymore, with so many charging stations available: https://supercharge.info/

    I have doubts about that.
