The AAA Automotive Research Center in Southern California performed a research study to better understand the effects of climate on electric vehicle batteries. The study concluded driving range could be reduced on an average of 57% depending on the temperature.
The simulation was used to measure the driving range of three fully-electric vehicles in cold, mild and hot weather. The batteries were fully charged and then driven until the battery was completely discharged. The study found that in extreme cold, the driving distance could be 60% lower and 33% lower in extreme heat than EPA ratings. The vehicles were tested between December 2013 and January 2014.
