    My 2015 Model S had a snowflake icon on the dash today next to the battery guage. I know this is an indication of cold weather but does anyone have any idea why it would be on at 9 degrees, off at 6 degrees (lower), back on at 5 degrees?

    Is there any additional logic other than the temperature? I looked in the manual on the dash but the icon wasn't listed.

    I believe it is that the battery, or a portion of it, is too cold to accept a charge. It sounds like it was warming up but as you were driving the cold air brought the packs temperature down again.

    Thanks, I had never seen it before. Makes sense with the snow, wind and single digit temperatures in Boston right now.

    IIRC this was introduced in 4.x but I figured they had since removed it. It indicates that the battery is very cold and that the range estimate may be inaccurate.

    Odd. The snowflake on the Mercedes, VW, Audi and Saab I owned always indicated possible ice conditions: 25 to 36 farenheit if memory serves.

    I have the same problem, outside is just -8 degrees and Tesla S is stopped charging, charger is green but car is calculating. I restart car and find out that Tesla start charging when doors are open. When I close, it stops charging.

    Your low state of charge is causing the vehicle to alter the charging process until the vehicle is safe to charge. This happens a lot with low SOC when arriving at a supercharger as well. Plug it in and close the doors and check back in a few hours, I'll bet you see charging then

    Before charging ramps up, the battery needs to be heated. That will take some time (an hour maybe) and use the shore power. Be patient.

    Yeah, I drove thru 3 days of 0F to 6F daytime temperatures this week. One morning I woke to -7F, got the snowflake icon. I had charged the night before, so I started driving. It took about half an hour before the snowflake went away and it allowed full regen. During that time, it was using maybe 500Wh/mile, eating rapidly into my reserve charge. Then it settled back to a more reasonable range and I was able to make the next SC with about 20 miles less remaining range than I was hoping for.

    The next morning, I went back and plugged in while I was having breakfast. Kept an eye on the charging rate thru the phone. For the first 20 minutes it said 0kW on the charging meter. Then it crept up to 2kW, 10kW, 30kW, finally 60kW after maybe 35-40 minutes. This time, the range at destination was much closer to estimated. Warming the battery at the charger is a good thing.

    It indicates a temporary lower battery capacity, which will increase as the battery warms (even without charging).

    10 degrees (celsius) appears to be the cutover point.
