Comment on How reliable are EV chargers?

• sky@codesink.io ⁨11⁩ ⁨months⁩ ago

  What car do you drive where charging stops are that long? My average Supercharging session in my base Model 3 is 9 minutes. That’s barely enough time to go pee and walk my dog.

  I strongly prefer road-tripping my EV because the natural breaks mean I arrive more refreshed and less sore.

  30-60 minute stops

  I literally just drove 2,077.37 miles from Central CA to Chicago over the last 3 days for another one of those trips, and the longest stop out of any of them according to TeslaFi was 26 minutes and that was only once, for a really long stretch in Wyoming that doesn’t have any chargers on it yet. Every other one was under 20 minutes, with most of them being around 10-15. The entire trip took 23 supercharging stops and added 4 hours and 23 minutes to the overall trip. That was with me running balls-out with autopilot set to 85 for as much of the trip as I could possibly do (e.g. slowing down for construction, etc), so my efficiency was only 65.66% which is pretty bad for my car.

  I don’t know what you’re doing, but you’re absolutely doing it wrong if you’re spending 30 to 60 minutes to charge every time.

    As a tesla owner for several years, I find this hard to believe. 15 minutes at a 250 kw charger doesn’t even get you 50%. Even if what you say is accurate, stopping 23 times is extremely annoying. When I dive like that I much prefer to just go straight through with minimal stops rather than have to pull over every hour

      I can go buy a surgery robot but that doesn’t mean I know how to use it. Just because you own a Tesla doesn’t mean you know how to road trip it effectively, or have one that can do what I literally just did. For example, an early Model S or X can only charge at 120KW no matter what charger you plug it into, ergo no, it can’t do this. But any long range or performance model 3 or Y certainly can.

      Part of the reason there’s so many stops (which I prefer and so do my wife and daughter, for that matter), is that if you keep the battery’s charge level between 10 and 50% from hop to hop, you end up spending much less time at chargers in general because you’re always charging at peak or very close to it. Sitting at a charger waiting for that last 10% at like 75kw from 70% - 80% is MUCH slower than hopping on down the road and charging at near peak at the next charger.

      It works, I know for a fact it works, and I brought the receipts! Here’s a few examples from my trip:

        Ok yeah if you only charge to 50%. But that would kill me. I hate stopping. And I do have a long range Y
