I have had my car since early March of this year, so I really have not seen real cold weather with the car yet (I am in the NYC area and we rarely see temperatures lower than 20). I generally arrive back at work, where I normally charge, with about 20% SOC, and very rarely less than 15%. This morning I saw the cold weather warning as I was pulling into work. It was about 50 degrees today and I had 19% remaining. I forget the exact warning, but it said something to the effect that if it got much colder there could be reduced power. I also noticed that at about 20% power left I lost the very top of the power curve. My question is if I could ever just lose range because of the cold, and at what temperature that happens? I know the car uses more in the cold for heat and battery heater and I will use more RMs. That is not my question. I am more concerned that the car would get stuck because I could not get to the lower 20% of the battery. Phrased differently, will the car allow you to use all the RMs down to zero, although at an accelerated rate, or is there a "cliff" where the range could just disappear?
