This is the first really cold day of the year, and our Tesla charged to 80% overnight and stopped. Since then, I pre-conditioned the car earlier today and thought I would take it out, but noticed it wasn't drawing any current from the UMC, so decided to check further. I turned the car on (opened door, sat down, pressed brake) and clicked the start charging button on the big screen, but no current was drawn. I then changed the setting to disable timed charging hoping the car would start immediately, but it did not. Called Tesla Toronto service center, and they said the battery would need to heat before charging, but I had already pre-conditioned via the phone app, and sat in the car for many minutes, no voltage shown on the charging screen, just 24A like usual, but strangely, 0 volts. The car does not show any evidence it is heating the battery in preparation for charging. I unplugged the charging cord from the car, blew in it (sometimes that fixes charging issues). Didn't help, when I plug it in, the charge ring glows blue, and will not change to green. Right now, the car is 69% SOC, down from 80% that it charged to last night. Meanwhile, I took my Smart ED to the movies, and it worked perfectly, and is charging right now, no issues. I'm going out to reboot it and see if that helps. Any experience/advice would be appreciated.
