As a severe heatwave blankets the US, we examine how extreme temperatures impact EV range from experts at Recurrent, specialists in battery health and longevity.
A severe heatwave is intensifying across the United States, affecting millions from the Midwest to the East and West coasts, with a staggering 6.4 million individuals now under an extreme heat watch. Temperatures are expected to soar above 100°F in numerous areas by next week.

I am re-publishing a comprehensive report from Recurrent that provides insightful EV battery health data for homeowners, consumers, and sellers alike, to be examined this June. Recurrent’s examine, “Summer season & Sizzling Climate on Electrical Automotive Vary,” checked out real-world knowledge from greater than 7,500 electrical automobiles within the US.
The electric vehicles’ performance is largely optimised when temperatures rise significantly. Electric vehicles’ efficiency drops by a mere 2-5% when operating within a temperature range below 90°F (32°C). Electric vehicles are equipped with advanced thermal management systems to effectively cool and protect their batteries.
Despite this, Recurrent’s battery testing revealed that electric vehicles can experience a significant reduction in range, losing up to 20-30% of their overall capacity in extremely hot temperatures, defined as above 95°F (35°C).
Will cold weather finally become a hurdle for electric vehicles?
Warmth detrimentally affects Electric Vehicles (EVs) in two distinct circumstances:
- An automobile’s thermal management system relies on power, therefore ensure you keep your battery fully charged to help the vehicle regulate its battery temperature effectively.
- Parking an electric vehicle in direct sunlight poses a greater challenge than parking it in shaded or open-air conditions. To avoid damage from prolonged exposure at the airport, consider designating a sheltered parking space for your vehicle, especially when extreme heat is predicted.
Air conditioning’s impact on electric vehicles’ efficiency and range depends on factors such as temperature, humidity, driving style, and vehicle design.
Running your air conditioner under typical summer conditions won’t significantly reduce its range or performance. While internal cooling relies on vital functions, excessive heat can still lead to substantial losses.
While air-conditioning systems have a relatively minor impact on electric vehicle (EV) ranges compared to resistance heaters, the temperature threshold at which the range starts to decrease is typically around 85 degrees Fahrenheit.
While cooling your electric vehicle’s cabin has a negligible impact in milder temperatures, the effect is significantly less pronounced compared to heating it in cold weather.
Cooling your Electric Vehicle (EV) on a hot summer day just got easier!

For individuals who pre-cool their electric vehicles (EVs) when plugged in, the air conditioning won’t impact the overall range? The most energy-consuming aspect of air conditioning systems is typically the initial cooling cycle. To cool a car to 70°F from 95°F requires around 3-5 kilowatts of power, whereas maintaining the temperature at 70°F only necessitates about 1 kilowatt.
While electrical air conditioners may boast ease of use compared to their mechanical counterparts, regular maintenance is still crucial; therefore, it’s essential to inspect air filters and hoses consistently.
As temperatures drop, many of us rely on our vehicles to provide a cozy retreat from the cold. But with the rise of electric vehicles (EVs), we must consider how their unique characteristics affect warmth. Traditional internal combustion engine (ICE) vehicles often struggle to maintain cabin temperature during extreme cold snaps due to reduced heat output.
Driving an electric vehicle (EV) is one of the most effective ways to reduce your carbon footprint and minimize your reliance on fossil fuels, especially during periods of peak energy demand when air conditioning is in use. Fossil fuel-based transportation is one of the primary drivers of climate change; electric vehicles (EVs) play a crucial role in mitigating this issue.
Winterize your electric vehicle (EV) for maximum performance.
