Electric vehicle (EV) batteries thrive in moderate temperatures, ideally between 65°F and 75°F. When it gets too hot or too cold, their efficiency drops. This means that in extreme weather, EVs won’t perform as well, resulting in shorter driving ranges.
Recent research from AAA highlights this issue. Their studies show that heat can reduce an EV’s range by about 8.5%, while cold weather slashes it dramatically by 39%. These findings align with past research conducted in 2019, which found similar losses in cold temperatures but higher reductions in heat. Greg Bannon, director of automotive engineering at AAA, explains that while advancements in battery technology and vehicle designs might help improve performance, EVs haven’t changed significantly in cold conditions over the past few years.
This doesn’t just impact electric cars. AAA also found that traditional gas vehicles suffer significant fuel economy drops in cold weather, with a range loss of nearly 23% in test conditions. The Environmental Protection Agency (EPA) estimates fuel economy drops of 10% to 30% for all vehicle types when temperatures plummet.
Interestingly, some regions, particularly Norway, have embraced EVs despite the cold. In March 2026, nearly 98% of new car sales in Norway were electric. This shift suggests that users can adapt to the challenges of winter driving with EVs, especially with the proper planning and adjustments.
Drivers can take several steps to maximize their EV’s performance in varying climates. Choosing the right vehicle that’s designed for either hot or cold weather is crucial. Resources, like annual tests conducted by Norwegian auto clubs, can guide consumers in making smart choices based on local weather conditions.
Preparation is key. For daily commuters who charge at home, the impact of reduced range in winter may be minimal. However, those without home charging or planning long trips should account for this range loss ahead of time. Additionally, warming up the car while it’s still plugged in can help preserve battery life. Using heated seats and keeping tires properly inflated can also enhance efficiency.
Overall, while EVs face challenges in extreme temperatures, thoughtful choices and behaviors can mitigate these issues, leading to a sustainable and efficient driving experience year-round.
