It is around 20 around here at the moment and I am getting about 55 mile range out of my leaf......
Here is a recent trip where the car went from 100% full to low battery warning and really made me wish I never bought the car:
Distance Traveled: 57.5
Average Energy Economy: 3.7 miles/kWh
Electricity Consumption 15.7 kWh
You just said you drove 57 miles to Low Battery Warning, which indicates a far greater range than 55 miles, wouldn't you agree? Your range doesn't end at LBW, but has about 17% more battery to propel you. NOTE: I do not use the dash mounted "GuessOmeter" to derive range data. It's far too unreliable or accurate.
So, 3.7 multiplied by 15.7 equal about 58 miles. That data makes sense, and with 17% battery power remaining at the first "Low Battery Warning", you have about 19kWh total in the battery. At a battery temperature of 70F, you'd have 21kWh, therefore the temperature on the battery reduced your total energy by 2kWh, or about 10%. Therefore, your total range
on your quoted trip is 3.7 (assuming the same energy consumption) multiplied by 19 equals 70 miles.
That's 3 miles less than the EPA rating of 73 miles; data you knew when you bought the car (or should have known).
But, I'm not going to make excuses for Nissan. They do a very poor job of trying to stating the facts, on purpose in my opinion, and all the above data is what we've worked out on this forum and amongst ourselves.
Considering your temperature of 20F, that's excellent range (you probably didn't want to hear that). If, in fact, the battery were 20F, I'd expect a much lower capacity.
Do you store the car in a garage? If not, can you? Any economy figures in the 3 range, like your 3.7, is fairly normal for new drivers to EVs. With a little work, you should be able to get above 4, which would help your range a bit. I think I read that you weren't using the heater, but presumably the seat and wheel warmers. That should save you a bunch of range.
Can you have yourself, or somebody else, install an electric battery warming blanket to the underside of the battery? That's very easy to do, and you can plug it in to 120v just like gasoline cars, to warm it up. CAUTION: Don't use an oil pan heater; they are too hot. Nothing over 100F/40C, please!!!
Preheat that cabin with the J1772 !!! Use your timer, or smartphone to activate it.
Charging the battery just before driving helps get the battery temp up, but eliminates an chance for cell balancing, which takes 1 to 4 hours after the battery reaches 100% charge and remains plugged in to the J1772.
