The charge speed throttling is permanent for the affected packs. It was in place before 2019.20, all the way back to 2017 and Tesla admitted it at that time.
Hi everyone. I just got off the phone with Tesla with some disturbing news. My car has approximately 30,000 miles on it. I regularly use CHADeMo to charge my car, with the occasional Supercharger charge on road trips. On my last road trip, I noticed that my supercharging rate was significantly...teslamotorsclub.com
I believe the eligibility criteria to be chargegated evolved over time so more cars got impacted. The fact is that we just did not know that was going to be the case when we purchased our cars.
I'm too lazy to pore through nearly 15,000 posts in this thread. But I recall that there were several people on here who stated that they rarely, if ever, utilized L3 charging, yet they noticed that at a recent session at a Supercharger their rates were nerfed as well.
If my recollection is accurate, then there is something else besides frequency or quantity of L3 charge sessions that triggers the reduction in speeds. Perhaps cell age is one factor. Perhaps the BMS loses efficacy over time.
I remember the snarky email from Musk in August 2015 suggesting that I (or anyone for that matter) charge at home instead of Superchargers. Never mind that I had taken two road trips in the preceding ten weeks to Milwaukee and Minneapolis followed by a trip to Portland OR and southeastern British Columbia. I wonder if this letter was an indication that things were not as rosy as originally claimed.
