Is a Cold Climate a Deterrent to EV Ownership?
This time of year, most people have one thing on their minds: the weather. As freezing temperatures descend across the country and snow and ice become a hazard, EV drivers face another potential issue—how cold affects the battery and range of their electric cars.
Cold temperatures do affect electric vehicles and steal some of their range. The amount of range lost depends on many factors such as the car itself, its potential range in normal weather, and whether the heat is on. According to AAA’s “Cold Weather Can Cut Electric Car Range by Over 40%”, EVs often lose 12% of their range in cold weather, but the loss leaps to 41% with the heater on full blast.
When EV Drivers think of cold weather, they think about the range of their car. There are many rumors and tales about EVs and cold weather. Are some or all of them true? Can EV range truly be reduced? Is there anything you can do to…

Electric Vehicles in Winter
Cold weather reduces efficiency of all vehicle types, not just EVs. According to FuelEconomy.gov, conventional gasoline vehicles typically have a 20% reduction in fuel economy at 20° F. However, it is often more noticeable with an EV and is especially concerning for all-electric vehicle drivers who need to know they have enough range to reach their travel destinations.
Keeping the inside of the vehicle warm in winter is usually the biggest drain on EV range, especially when ambient temperatures plunge below 15° F. Lithium ion batteries used in EVs also do not perform as well in cold temperatures, which can lead to further range reductions.
*Chart*
Getting through the winter in your EV begins with purchasing the right vehicle for your needs. Most new all-electric models offer more than 200 miles of official range, so even with winter reductions many EV drivers are rarely inconvenienced by these issues. On the other hand, older used EV models may offer less than 100 miles of range which can present significant challenges if drivers aren’t aware of winter reductions when purchasing.
