According to research conducted by the AAA Automotive Research Center in southern California, electric vehicle (EV) range can be reduced by an average of 57 percent based on the temperature outside.
To better understand the impact of climate on electric vehicle batteries, AAA conducted a simulation to measure the driving range of three fully electric vehicles in cold, moderate and hot weather. Vehicles were tested for city driving to mimic stop-and-go traffic and to better compare with EPA ratings listed on the window sticker. The vehicles were fully charged and then “driven” on a dynamometer in a climate-controlled room until the battery was fully exhausted.
The average EV battery range in AAA’s test was 105 miles at 75°F but dropped 57 percent to 43 miles when the temperature was held steady at 20°F. Warm temperatures were less stressful on battery range but still delivered a lower average of 69 miles per full charge at 95°F.
