We are only 5-6 years into the car ev market. Tesla model 3 started being sold in 2018 in meaningful numbers

Still have mine. Battery capacity is around 80% of the new capacity. I'm not planning on switching anytime soon as it's got plenty of range still. I'll probably swap the pack out when it hits 70% in the next 2 or 3 years.

  It probably will take a lot longer than that to hit 70%. Degradation on Tesla batteries slows down considerably after it hits 85%. there are exceptions, though.

  Your 2018 tesla has a battery SOH of 80%? How many km's on the clock, and how often do you fast charge if you dont mind me asking? To me that SOH stat sounds really bad!

    I agree, reads like carefully crafted FUD.

      What possible motivation would I have to spread FUD about my own car? To me this is perfectly reasonable degradation after 7 years of ownership with the number of miles I have. There is also just an element of luck that's involved. Batteries degrade at different rates and there's not really any accounting for it.

    270,000 km. And fast charging about 3 times a year. If I were to guess, the main factor harming the battery is my garage gets pretty hot in the summer (37 or 38C)

      That is quite high mileage. I'm certain someone smarter and less lazy than me can calculate the amount of expected cycles that the battery would have seen. Do you leave it fully charged for long periods of time, or do you discharge it down to empty or nearly empty quite regularly?
      - cogman10 1y ago
        I charge it to 70% and leave it there most of the time. I don't often fully discharge, that's bad for the lipos. I usually keep a 40-70 range SOC.

      I'm not even sure how to calculate our deg! Same, 2018 3 long range. I think they advertised it as 305mi but some time later increased the capacity of the car to 315mi; I max charged it to 314 once but never quite saw that 315. I think we're around 273 as max now so 89.5% of the original quoted life, 87% of the "updated" life. Car has 115k miles, ~ 185,000km.

        There was about 2 years of rapid drop off that I experienced and I don't exactly know why.
