This analysis covers Sep 2015 to end 2018 - about 3 1/4 years of data, about 16,000 miles of driving over almost 4,000 trips. My average efficiency for the entire period was 4.55 miles/kWh.
I used the "Electric Rate Simulation" data for my car from the Nissan website that provides daily trips, distance, and electricity information.
I grabbed the daily weather data that provides high and low temperature for the day, then used those data to compute the average temperature for the day.
I can now estimate the impact of temperature on range. Admittedly using a single temperature value for an entire day is crude, and the data from Nissan isn't exactly entirely correct, but I'm just getting a sense of the impact of temperature on range.
The upshot is that yes, cold temperatures have a considerable impact on range. I added the number of miles driven for each temperature range to give an idea of the weighting - I didn't drive many miles when the day's average temp was below 20 F or above 75 F.
