AAA Research Lays Out How Temperature Affects EV Range

While we all know extreme temperatures influence the performance of electric vehicles, there isn’t a wealth of comprehensive studies on the matter. Hoping to impart some knowledge on the subject, the American Automobile Association released a report on Thursday that examines how climate impacts EVs.

AAA offered an abridged version in 2014, when it claimed data from its Automotive Research Center (ARC) showed battery-only driving range can be nearly 60 percent lower in extreme cold and 33 percent lower in extreme heat. However, the new study fine-tunes those numbers while exploring other avenues of how EV performance can suffer.

  • Probert There's something wrong with that chart. The 9 month numbers for Tesla, in the chart, are closer to Tesla's Q3 numbers. They delivered 343,830 cars in q3 and YoY it is a 40% increase. They sold 363,830 but deliveries were slowed at the end of the quarter - no cars in inventory. For the past 9 months the total sold is 929,910 . So very good performance considering a major shutdown for about a month in China (Covid, factory revamp). Not sure if the chart is also inaccurate for other makers.
