My daughter took my 3 to go skiing in Bend OR and was at this supercharger last night and tried 4 different stalls and couldn't get a stable charge. It would ramp up as high as 100kW and then the power level would bounce all over the place and then drop back to zero then ramp back up, bounce around, go to zero and repeat tried for 15 minutes and never stabilized and seemed to get worse as time went on staying at 0kW for longer periods of time before rebounding. Called Tesla roadside said they had a call the previous night about this location doing the same thing for someone else but they were able to get it to work by turning the car off for five minutes. Didn't work for us, she finally had to get a slow charge at a local hotel.
It seems to me the problem is the Supercharger but I dont know of any failure mode that would affect all stalls. Temperature was 17F but the car had been driven for 3 hours and the battery was at 30% SOC, Ive charged my S at this location fine under the exact same circumstances at this supercharger in the past. So, problem with the car?, the supercharger? or just the weather?
