How well can EVs handle the heat — and the cold? AAA put them to the test
AAA tested electric vehicles in extreme temperatures and found that hot temperatures reduced range by 8.5% on average, while cold weather cut range by 39%. The results show that drivers need to adjust for predictable range loss in winter and summer.
AAA tested electric vehicles in extreme temperatures to determine their range. The tests found that hot temperatures reduced range by an average of 8.5%, while cold weather cut vehicles' range by 39%. Compared to similar tests in 2019, the high-temperature range loss improved from 17%, but cold weather performance remained similar. The tests were conducted at AAA's Automotive Research Center in Los Angeles using a chassis dynamometer, a 'treadmill for cars'. Drivers need to plan for range loss in extreme temperatures, but EVs can still be practical choices in hotter or colder climates. The research was done to benefit auto club members and help them understand EV performance.
