Canary Media’s Electrified Life column shares real-world tales, tips, and insights to demystify what individuals can do to shift their homes and lives to clean electric power.
Andrew Garberson isn’t worried about his electric vehicle handling cold winters.
He recently drove his EV to the gym when the temperature where he lives in Des Moines, Iowa, was a biting 4 degrees Fahrenheit. A polar vortex had brought a brutal wind, “the kind that whistles in the cracks of the car doors when you drive.”
Garberson relies on his electric truck, a graphite-gray Rivian, for year-round family road trips to see his parents, who live a few hours away. “My car will drive 200 miles in freezing conditions in the Midwest,” said the head of growth and research at Recurrent, a company that aggregates data on battery health from more than 29,000 EVs across the United States.
Switching from a gas car to an EV is one the biggest actions an individual can take to reduce their emissions. But EVs have gotten something of a bad rep in cold weather. It’s true that they, like gas cars, lose range as temperatures fall: Depending on the EV, the drop can be 16% to 46%. That loss may be anxiety-provoking, especially for EV owners-to-be.
From Garberson’s perspective, the criticisms are overblown. EVs work even in the most bone-chilling climates across the continental U.S., he said. In any case, Recurrent has found that knowledge and experience go a long way toward relieving those fears.
Plenty of frosty regions are embracing electric cars. Just look at Chicago. Despite its freezing winters, it’s one of the top cities for EV registrations, with more than 25,000 in the 12 months ending in June 2024, according to Experian’s most recent available data. Outside the U.S., the trend holds, too: In Norway, where temperatures can drop below -4˚F, nearly 9 out of 10 new cars sold in 2024 were fully electric.
In this article, we’ll dive into how to get the most winter range out of an EV. First up is a key EV feature to look for if you’re still shopping. Then, for those who already have an electric car, Garberson shares his top range-extending strategies.
EV range shrinks in the cold partly because the chemical reaction in their massive lithium-ion batteries slows down. But the biggest reason for winter range decline is the need to keep passengers warm, Garberson said.
Gas cars use the waste heat generated from the internal combustion engine for cabin heating. EVs don’t have an engine (they have a motor), so they don’t produce enough accidental heat to keep occupants cozy in frigid weather. Instead, EVs siphon energy from the battery to heat the cab, leaving less for propulsion. EVs can either make heat with an electric-resistance heater, which is like turning on a toaster, or much more efficiently move heat from the outdoors into the car using a heat pump.
Heat pumps are famous for their critical role in decarbonizing space heating in buildings. They don’t burn fossil fuel, and they’re typically two to three times as efficient as gas and electric-resistance systems, even below freezing. But the tech has also made its way into clothes dryers and water heaters. Now found in some EVs, heat pumps improve range by 8% to 10% in cold conditions, according to Recurrent.
According to Recurrent’s analysis, electric vehicles with the best winter range tend to have heat pumps, including the Tesla Models X, S, 3, and Y; Audi e-tron; and Hyundai Ioniq 5 and Kona.
It’s worth pointing out that heat pumps themselves are less effective as temperatures drop. Even so, EVs with heat pumps offer better range than those with electric-resistance heating. Recurrent points out that at 55˚F, a heat pump reduced range by 20% while a resistance heater lowered it by 33%. As the weather gets colder, the difference in range between EVs with heat pumps and those with resistance heaters shrinks.
To be clear, EVs work well in the winter even without heat pumps, Garberson said. His Rivian truck doesn’t have one, and on a day-to-day basis, he doesn’t even notice the decline in range. He charges at home, which makes topping up easy. For longer road trips, cold weather might mean he needs one more charging stop than he normally would.
Heating technology aside, drivers can take steps to get more out of their EVs in the cold. Recurrent’s Garberson offered his top three range-saving strategies for winter EV drivers.
Prewarm your EV while it’s plugged in. Garberson’s garage isn’t climate-controlled, so his vehicle gets chilly when the weather does. About 10 minutes before he hops in, he uses his car’s app to warm up the cabin. Pulling electricity from the wall outlet means he won’t have to use the battery to bring his car from 4˚F to a toasty 70°F.
Set your charging limit higher. Batteries are happiest when balanced at 50% charge, Garberson said. Because huge charge-level swings are harder on the battery, Recurrent recommends keeping it between 20% and 80% full. But “let’s eliminate anxiety from the discussion and just charge cars a bit more in cold conditions,” he advised. If you normally charge to 70% to keep the battery healthy, as Garberson does, increase it to 80% in the winter.
When you’re headed to a fast charger, set the destination in the car’s GPS, a feature in most modern EVs. Letting the EV know will allow it to start preconditioning the battery so it’s ready to charge when you get there. Otherwise, you may need to wait 15 to 20 minutes at the charger for the battery to warm up sufficiently, Garberson said. “It’s just amazing how [electric] vehicles have been designed over the last few years to help drivers without them even knowing.”
One more tip for your kit? Turning on the heated steering wheel and heated seats “is a far more efficient way” to warm yourself and passengers than heating up the air in the car’s cabin, Garberson said. Once the car is prewarmed and you’re on the road, you could dial down the thermostat and use the targeted heat features to keep you cozy.
But most importantly, Garberson added, do what you need in order to keep yourself and your passengers happy. He’s father to a one-year-old, so “relying on heated seats is not part of my driving equation.”
Besides, “I will admit I am kind of a sucker for creature comforts,” Garberson said. “I need heat any way I can get it.”
Manufacturers provide even more advice on how to extend the winter range of your particular EV model, so be sure to check out their online guides.
A little planning and know-how can go a long way toward a smooth EV experience in frosty weather, Garberson said. Winter takes a bite out of his EV’s range, yes, but “I get by just fine.”
