I usually charge indoors with my HPWC when I'm at home, but at my cottage, I use my UMC with a 14-30 adapter to charge while parked outdoors. I took delivery of my S85D in June, so this is my first winter experience. On New Year's Day, the car was covered in several inches of snow, temperature was just below freezing. I used my Android Tesla app to increase charge limit so that I could return home the next day. Right away I got a flurry (sorry) of notifications, approximately every 5 seconds, alternating between "charging started" and "charging interrupted". I ran out to the car to see what was going on: the light around the charger ring was alternating between blue and green as charging was starting then stopping again. In the past I've always been careful to make a "drip loop" so that any water accumulated on my UMC cable would drip down instead of entering my charge port. I did notice the charge port was covered with snow, so I gently took my finger and removed the snow from the illuminated ring, being careful not to disturb the charge plug. After doing this, charging finally started and kept charging without any interruption. Has anyone else ever experienced this?
