Range and Temperature

I have collected temperature data this year in an attempt to understand a little more about what effects range the most from summer to winter.

I have logged my drive to work temperature, drive home (From Work) temperature and charge temperature.

It looks like the highest correlation with projected range is the drive home. That may simply reflect the daytime temperature of course.
Temperature is in degrees C.
