Do you have a link to an official statement on DC Superchargers from Tesla? The best I could find was them stating that use of Superchargers will not affect the pack warranty. I did however find this article (https://electrek.co/2017/05/07/tesla-limits-supercharging-speed-number-charges/ https://electrek.co/2017/05/07/tesla-limits-supercharging-sp...). This seems to imply that the packs are damaged by repeated Supercharger use and will automatically throttle themselves to lessen the damage being done. Tesla seems to be very coy and dances around the subject because they don't want to attach any stigma to fast charging while EVs are still in their infancy as it might negatively impact their adoption rates.

Every time you charge a battery it helps to throttle charging if the temperature is out of range. Tesla has always done this; there's an extra fan that's Extremely Loud and I only hear it when I'm supercharging on a hot day. In the article you linked, the customer appears to have noticed a slight decrease in the peak charging rate. It doesn't sound significant to me. There are certainly other Teslas out there which are supercharged 100% of the time, Tesloop is one example.

That's one of the three reasons Tesla gives for throttling the charge rate. > In the article you linked, the customer appears to have noticed a slight decrease in the peak charging rate. From 120kW down to 90kW peak charging rate is only slight? I realize it's peak and not average but a 25% reduction is only considered slight? Also you said that Tesla disagrees with me about the affect of DC fast charging on battery life. The statements from Tesla seem to agree with me and they have implemented technologies to mitigate those effects in the form of peak rate throttling over time. You seem to misinterpret Tesla saying it's fine to DC Fast Charge to mean that it has no detrimental affects when they really mean that they have protocols in place to ensure the pack will not degrade to the point that a warranty replacement is necessary.
