I have a 85D that I took delivery of a month ago. Most of my charging is done at work and my round trip commute is about 30 miles. The car seems to use 40-50 miles depending on traffic, temperature, and driving style, which I completely understand. I charge daily to a point where the car sits in my garage at 50% charge overnight, and the garage never drops below 50 degrees. I am having a charging outlet installed this weekend and that will probably only be used on the weekends. I also normally set charging to begin at a time that finishes it right about the time I am leaving. Normally my work charge rate is 26mph, at about 212-215 volts and 39-40 amps. This morning was the first moderately cold day I had the car, and it was in the high 20s. I noticed the charging rate was only giving 10mph at 16/40 amps. This has been going on for over an hour. I am assuming it is due to the cold? When it gets really cold, is this the charge rate I can expect or does it heat up at some point and get to the higher rates? I would like to know so I can plan when I need 100 miles of charge.
