Really hot weather also affects EV range (up to -31%).

A new study suggests that excessive heat can greatly diminish electric vehicle range. The findings are similar to other studies that show how excessive cold also reduces range. Thankfully, it seems as though the range is mostly unaffected unless the temperature is in the triple digits.
Seattle-based Recurrent studies and tests thousands of vehicles each year in order to analyze the relationship between batteries and their range. Its latest data indicates that when things get really hot, EVs could lose almost a third of their stated range. While Recurrent didn’t name names, it says that some vehicles saw a drop in their range of 31 percent when temperatures climbed above 100 degrees Fahrenheit (38 degrees Celsius).
Recurrent is the same company that last year found that freezing temperatures have a nearly identical effect. Both the Ford Mustang Mach-E and the Volkswagen ID.4 saw dips in range of 30 percent when temps dropped below 30 degrees Fahrenheit (-1 degrees Celsius). At the same time, it’s worth noting that less extreme temperatures exhibit very little influence on battery range.
