A current heat wave affecting the Central, Midwest, and Northeast U.S. poses challenges for electric vehicles (EVs), especially as temperatures soar over 90°F. A study by Recurrent analyzed data from nearly 30,000 EVs, revealing that while some range is lost due to battery thermal management systems working harder to maintain cool temperatures, the efficiency drop at 90°F is minimal compared to when it reaches 100°F. Despite this, manufacturers like Tesla recommend avoiding excessive temperatures for extended periods to ensure battery health.
Extreme heat causes electric vehicles to lose some range due to thermal management systems working harder to keep the battery cool, using up energy in the process.
A recent study analyzed real-world data from 29,719 electric vehicles, revealing minimal range loss at 90F, with more significant drops when temperatures reach 100F.
