    Did you report the problem to Tesla?

    I have seen this exact behavior last week too. MX P100D 85 Degrees outside, no one else charging. 115KW for the first 10-15% then drop to 60KW. The eta for finish charge was off by 20 min too.

    I'll mention that to Tesla too then... but where the hell did you get 115kW? The most I got was like 95, I thought the limit was like that. Was that because of a bigger battery?

    Bigger batteries can take higher charging power.

    i found a work-around for this as it was happening to me on my last OH-NJ/NY-OH trip.

    basically after it slows down to 60kw i would unplug and move to another stall and it speeds up again. try not to burn yourself on the charging handle as it will be very hot.

    my conclusion was that it could sense that the handle was heating up due to the high amounts of power being dumped into the battery...

    at one Supercharger when i came back to the car and i wasn't finished charging and couldn't figure out why, then i noticed that i was creeping along at 60kw. i moved from 3B all the way over to 1A (i was the only person at the supercharger) and it immediately went shooting up to 101KW and we were able to leave 5 minutes later! :) just some of the quirks we have to deal with i guess...

    As @Peteybabes mentions, I would try another stall next time you see this issue. It happened to us once at the Silverthorne Supercharger. We moved to a different stall and that solved the issue.

    That's happened to me. I did call but they didn't seem to think it was a problem, just that "that's what the car is calling for". Next time I will check out the handle temperature.

    60,70,75 kWh batteries are 350V batteries (max charge rate closer to 100 kW)
    85,90,100 kWh batteries are 400V batteries (max charge rate closer to 120 kW)

    The same behavior was not there in @Bjorn 's recent video, so I don't think it's normal... Tesla need to resolve this...

    I always charge at the 4A spot of the 7-stall superchager so I always have all power to myself, so I don't want to move lol

    Call the supercharger number while you're plugged in. Last time I was in that situation, the rep was able to pull up the data and tell me stalls were showing "fluctuating power" and only stall 3a was full up. Plugged into 3a and sure enough got full 110kW.

    Sometimes it's a stall issue (not handle specifically), but it can also be dirty contacts on the specific handle. This leads to a high resistance in the connection which heats up the handle rapidly (just being at night would not help very much in this case).
