Over the past months I have been dealing with a steadily escalating number of incidents with V2 superchargers. Firstly I want to say that I have had 3 different Tesla's over the past several, and am quite familiar with each cars charging curve, and the dynamics of supercharger stalls both in shared and dedicated configurations. I know what to expect at what state of charge and in which weather conditions. I also drive the same or similar long distance routes for work, about 1500-2000 miles a month, so I am familiar with the foibles of specific bad performing superchargers, and which ones should be reliable. Service has already completed diagnostics on my vehicle and determined that the car is not requesting throttling, and that with my current pack health and usage I should be seeing full speeds. I also want to say that my cars performance at V3's is completely as expected every single time, I have had zero lifetime poor charging sessions at these stations. My old 100D still get's almost 190kw peak. I also have not had occasion to test our new 2021 model 3 to see if the problem can be reproduced, as the vision speed limiter / auto-high-beam combo has made it uninviting for long trips.
I have had this trouble at completely empty stations, no other cars present. When I pull into a station and first plug, charging starts in a normal amount of time, and it ramps up to about 84kw immediately. In a normal session it will then proceed on all the way up to about 145kw. However during these trouble sessions, the time remaining to my charge target will be double what I expect right from the moment I plug in the vehicle. It will spend a couple moments at ~84 kw, and then either settle to 72kw or 60kw for the rest of the session. If I unplug and re-plug, sometimes it will jump up to 145kw for less than 30s before dropping back to 72kw or below. I used to be able to find 1 or 2 stalls in a station where I was able to get full speeds, sometimes having to try all of them, but as of this weekend I have been unable to get over 72kw on at least three different V2's in my region. I am going to a different part of the midwest later this week, and on the one hand, would like to take my 100D to see what rates I get, on the other hand, don't want to add an extra hour to my trip. Fast charging > 80mph vision cap. Unfortunately there are no V3's on my route this week, otherwise it would be a non-issue.
Has anyone else had experiences like this lately? Is there a problem like a worn charge port that could cause this (V2 cables are heavier so make poor connection vs V3)? Or is the network generally aging poorly and this is just a thing now?
