I live in Madison, Wisconsin, US where our winters are cold -- for January and February, the average low is around -10C, with extremes regularly dipping below -20C.
I currently have a 20-year old car. Soon enough, I expect that needed repairs will cost more than the value of the car. When I replace it, I would like to buy an electric vehicle. The problem is, for most of the year I do a majority of my commuting by bicycle, so that I only really use the car during the very cold parts of the year.
However, I've heard that cold weather can reduce electric vehicle range. Is this true? Has the effect been quantified? Does it vary based on model?
