The test parameters in the study quantified the cold, and kept the cars in the cold for 14 hours - that seems like good methodology.
Prior to testing, the tyre pressures were set to the manufacturer recommendation, before the cars were fully charged and left outside overnight for roughly 14 hours in temperatures that ranged from 0 to 2 degrees centigrade.
Then the cars were driven in formation - also good methodology.
I have no problems with their methodology or study, other than the heater part. How much of the range decrease was due to the heater? That is my question.
An ideal test temperature would be more like -15C, but that really depends on the weather in the location. -40C would be very interesting to see for sure.
After reading so many stories about "range anxiety" for electric car drivers, if the choice was between an extra 3% battery life and warmer temps inside, I think drivers would opt for the range.
