How much range does an EV lose in winter? Between 14 and 39 percent, depending on the car, and the spread inside that band says more about how you use the thing than which badge is on the bonnet. The Canadian Automobile Association got 14 percent out of a Polestar 2 and 39 percent out of a Volvo XC40 Recharge on the same road, on the same day, in the same weather. Most of that gap is recoverable. Four of the five fixes below cost nothing.
The short version
Most EVs lose 20 to 25 percent of their range at freezing and around 30 to 39 percent at minus 7°C. Preheating the cabin while still plugged into the wall is the single biggest fix, worth roughly 10 to 20 miles on a 250-mile car. A heat pump is worth another 8 to 10 percent, but only if you buy one.
How much range does an EV lose in winter, by the people who measured it
Four organisations have published real numbers, and they disagree in useful ways.
- Recurrent pulled telematics from more than 30,000 cars across 34 models and, in its winter range study updated 19 November 2025, found they held 78 percent of their range at 0°C on average, and 70 percent at minus 7°C. Best in the set kept 88 percent, worst 69 percent.
- AAA put three EVs and three hybrids on a chassis dynamometer with the cabin set to 22°C and the test cell at minus 7°C. Its report of 1 May 2026 measured a 35.6 percent efficiency drop and a 39.0 percent range drop. That is the worst case: heater on, full blast, the whole time.
- CAA drove 14 EVs from Ottawa to Mont Tremblant at minus 7°C to minus 15°C on 10 February 2025. Losses ran from 14 percent (Polestar 2 and Chevrolet Silverado EV) to 39 percent (Volvo XC40 Recharge).
- Consumer Reports ran a Mustang Mach-E, an Ioniq 5, a Model Y Long Range and an ID.4 on a 142-mile Connecticut loop at a steady 70 mph. Its test updated 17 January 2024 found about 25 percent loss at minus 9°C. On short stop-start trips the loss doubled to 50 percent.
That last line is the one worth remembering. The motorway number and the school-run number are not the same number. Cold air does slow the chemistry in the pack, but Recurrent is blunt that cabin heating is the primary cause, and heat is a cost per hour, not per mile. Sit in traffic and it eats you alive.
The fixes, ranked by the miles they give back
The percentages below come from the studies named above. The miles column is my arithmetic applied to a 250-mile EV at about minus 7°C, so treat it as a sense of scale rather than a promise. Checked 16 September 2026.
| Fix | Roughly what it returns on a 250-mile EV | Where the number comes from | What it costs you |
|---|---|---|---|
| Heat pump instead of a resistive heater | 20 to 25 miles | Recurrent, 25 November 2024 | Nothing, but only available when you buy the car |
| Preheat cabin and pack while still plugged in | 10 to 20 miles | Recurrent and CAA | Nothing |
| Seat and wheel heaters, cabin set low | 8 to 15 miles | CAA winter guidance | Nothing |
| Winter tyre with a good rolling resistance class | 5 to 12 miles versus an aggressive winter tyre | EU tyre label classes A to E | Nothing extra at fitting time |
| Tyres back up to the door-sticker pressure | 4 to 8 miles | AAA, 1 PSI lost per 10°F of cooling | Five minutes with a pump |
| Brush the snow off, park indoors when you can | 3 to 8 miles | CAA winter guidance | Nothing |
Notice what is missing: eco mode, coasting, hypermiling. On a cold day those move the needle far less than the heater does, because the heater is drawing two to six kilowatts whether you are doing 20 mph or 70.
Should I preheat my EV while plugged in?
Yes, and it is the one habit that separates owners who complain about winter from owners who barely notice it. Recurrent puts the logic plainly: it takes more energy to warm a cold car than to keep a warm car warm. If the car is still on the cable when that first big heat surge happens, the electricity comes from your wall, not your pack.
The detail people get wrong is timing. Set the departure time in the app the night before rather than jabbing preheat from the kitchen window with eight minutes to spare, because a scheduled departure also warms the battery, and that takes far longer than warming the cabin. On a Model 3 at minus 10°C it runs 30 to 45 minutes. Eight minutes of cabin heat just clears the glass.
Do it even on a home charger you think is slow. A 7 kW wallbox covers a 4 kW heater draw and still puts charge in. Do not unplug until you are reversing off the drive.
Does a heat pump help EV winter range?
It does, and by more than most spec sheets let on. Recurrent’s heat pump analysis of 25 November 2024 put the benefit at 8 to 10 percent of winter range at around minus 1°C. Its cleanest comparison: an older Tesla Model 3 with a resistive heater used 26 percent more energy, a Model Y with a heat pump used 8 percent more. Same company, same software, same weather, three times the penalty.
You cannot retrofit one. The refrigerant loop is tangled into the pack cooling circuit, so this matters when you are shopping, not when you are shivering. Check by model year and by market: several manufacturers added heat pumps mid-cycle, and some markets got one on a car that shipped without it elsewhere. Read the build sheet, not the brochure.
Do winter tyres reduce EV range?
A bit, and it is the wrong thing to worry about. I could not find one controlled test of the same EV on the same route with winter tyres and all-seasons, which is a real gap in the published record. What is measurable is the rolling resistance class on the EU tyre label, where A to E spans enough to swing an EV’s consumption by several percent.
So choose by label class, not by the word winter on the sidewall. Several makers now sell EV-specific winter patterns with a stiffer casing and a better class, and those are the obvious pick on a heavy car. Our guide on when to fit winter tyres covers the temperature threshold. Losing 5 percent of your range is cheaper than sliding through a junction.
Pressure is the free win and almost everyone ignores it. AAA’s figure is about 1 PSI lost per 10°F of cooling. Set them on a mild October afternoon and by the first hard frost you are three or four PSI down on all four corners, enough to trip the warning light and quietly cost you range. Check them cold, against the door sticker.
Why does my EV charge slower in the cold?
Because lithium cells cannot safely take high current until they are warm, so the car throttles the rate to protect the pack. I have sat at a 350 kW rapid in January watching 34 kW crawl across the screen while the car heated its own battery on my time and my money.
The fix is battery preconditioning, and it is not the cabin preheat button. You trigger it by routing to the charger in the car’s own navigation, which warms the pack while you drive. The NAF and FIA El Prix test ran 24 EVs in Folldal, Norway in January 2026, down to minus 32°C, and found that cars using preconditioning came close to their stated 10 to 80 percent charging times. The rest did not.
CAA’s numbers show how wide the gap gets. In 15 minutes of rapid charging in the cold, its 14 cars added about 100 km on average. A Tesla Model 3 added more than 200 km. A Toyota bZ4X added 19 km. That is the difference between a coffee stop and an afternoon. If you are shopping for a car with a native NACS port, ask about its cold charging curve before you ask about peak kilowatts.
FAQ
Is fast charging in freezing weather bad for the battery?
No, because the car will not let you do the damaging version. Modern EVs limit the charge rate until the pack reaches a safe temperature, which is exactly why cold charging feels slow. The wear risk comes from forcing high current into a cold pack, and the battery management system exists to stop that.
Does an EV lose charge just sitting outside overnight in the cold?
A little, and mostly not from the pack. Some cars run pack heating overnight to stay above a minimum temperature, which draws a few percent. The bigger cold-weather failure is the 12V system, which is what strands most EVs in January. If your car will not wake up on a freezing morning, read up on an EV 12V battery dying before you blame the traction pack.
How much more does an EV cost to run in winter?
AAA’s May 2026 study put it at an extra 32.11 US dollars per 1,000 miles when charging at home, and an extra 76.93 US dollars per 1,000 miles on public rapid chargers, both at minus 7°C. Charging at home is what keeps winter cheap. The same test found only an 8.5 percent range loss at 35°C, so heat is a far smaller problem than cold.
Will turning the heater off actually get me home?
It will help, but do not sit in a freezing car out of principle. Seat and wheel heaters pull a few hundred watts against the two to six kilowatts a cabin heater draws, so dropping the cabin to 17°C and switching the seat on buys most of the comfort for a fraction of the energy. CAA says the same after 14 cars and a Quebec winter.
