Just downloaded my last 11 months figures off the Nissan website: very clear evidence of the winter/summer effect on range and energy efficiency for my 2013 Leaf: I'm driving about 1,000 miles a month or so: June 2015 figures are unavailable due to a carwings glitch:

Jan/2016 0.34 kWh/mile
Dec/2015 0.31 kWh/mile
Nov/2015 0.34 kWh/mile
Oct/2015 0.29 kWh/mile
Sep/2015 0.27 kWh/mile
Aug/2015 0.24 kWh/mile
Jul/2015 0.26 kWh/mile
May/2015 0.25 kWh/mile
Apr/2015 0.29 kWh/mile
Mar/2015 0.32 kWh/mile

How much of that is due to effect of the cold on the battery and how much on the use of the climate control.
I don't suppose you fancy driving for a whole year in the cold so we can compare your data?

If it's a gen2 Leaf the climate control impact is minimal, cold temps are a bigger issue and even more than that it's headwinds and heavy rain that are the main problem. Put them all together and it has a severe impact on an EV, on any car in fact.

It is a Gen 1 Leaf, unsure how much difference that makes. I'm pretty light on the heating, usually pre-heat, and wear warm clothes, but keep the demister on a couple of bars when its wet and cold to stop the screen turning into soup.
