Why EV Range Drops in Winter, and What Actually Helps

If you've driven an EV through a cold snap, you've seen it: the range estimate drops, and the battery seems to empty faster. That's normal, it's temporary, and there's a lot you can do to soften it.

This guide pulls together three well-known sources of data (a lab study from AAA, real-world fleet data from Recurrent, and the large Norwegian winter test from NAF), explains why range falls, and lists the habits that make the most difference.

How much range do EVs lose in the cold?

AAA lab test: up to 41% with the heater on

In a 2019 study, AAA tested five EVs on a dynamometer in a temperature-controlled test cell. At 20 °F (about −7 °C) with the heating on, average range fell by 41% compared with driving at 75 °F (about 24 °C). In other words, 100 miles of range became 59 (AAA).

AAA's key finding was that climate control, particularly heating, has "by far the greatest effect". Hot weather matters too: at 95 °F (35 °C) with air-conditioning, range fell 17%. AAA also estimated that heating at 20 °F added almost US$25 per 1,000 miles in charging costs compared with mild weather (AAA).

The study is from 2019 and the cars were older, so treat it as a picture of the effect rather than a figure for today's models.

Recurrent real-world data: about 70–78% of range retained

Recurrent, which analyses battery data from connected cars, looked at more than 30,000 vehicles in the US. On average, EVs kept about 78% of their range at 32 °F (0 °C) and about 70% at 20 °F (−7 °C). The best model kept about 88% at freezing and the worst about 69% (Recurrent, Nov 2025).

Recurrent also found that heat pumps helped, adding roughly 10% more range at freezing, but that the advantage faded as temperatures approached 0 °F (about −18 °C) (Recurrent).

Norway's El Prix winter test: 38% below WLTP on average

Norway's motoring association, NAF, runs a large real-road range test each winter. In the winter 2026 test, carried out at temperatures between −7 °C and −32 °C, cars on average fell 38% short of their official WLTP range. The biggest gap was a Lucid Air, which drove 519 km against a WLTP figure of 960 km (−46%). The best performers lost around 29% (NAF, Feb 2026).

For comparison, NAF's previous winter test, run in milder conditions of −6 °C to +8 °C, found an average shortfall of about 18% (NAF). Temperature makes a big difference.

Putting it together

Source Conditions Range lost
AAA (2019, lab) −7 °C, heater on 41% average
Recurrent (2025, real-world) 0 °C about 22% average
Recurrent (2025, real-world) −7 °C about 30% average
NAF El Prix (winter 2026) −7 °C to −32 °C 38% vs WLTP, average
NAF El Prix (winter 2025) −6 °C to +8 °C about 18% vs WLTP, average

The numbers aren't directly comparable, since methods, cars and baselines differ, but they agree on the pattern: expect to lose roughly a fifth to a third of your range around freezing, and more in deep cold.

Why it happens

Two main things are going on:

  1. Heating the cabin takes energy. A petrol car heats its cabin with waste heat from the engine. An EV has to use battery energy, through a resistive heater, a heat pump or both. AAA identified heating as the single biggest factor in its tests (AAA).
  2. Cold batteries work less efficiently. A cold battery can't deliver or accept energy as readily, and the car may use energy to warm it. Recurrent notes that cold batteries also charge more slowly (Recurrent).

Short trips in the cold are especially hard on range, because the car spends a large share of the trip warming up the cabin and battery.

The good news is that winter range loss is temporary. It isn't permanent battery damage, and range comes back when temperatures rise (Recurrent).

What actually helps

1. Precondition while plugged in

Warm the cabin (and, if your car supports it, the battery) while the car is still connected to the charger. Both AAA and Recurrent recommend this, because the energy comes from the grid rather than your battery (AAA; Recurrent). Many EVs let you schedule this in the app or the car's settings; check yours.

2. Use seat and steering-wheel heaters

Heating your body directly uses much less energy than heating all the air in the cabin. Recurrent recommends using heated seats and steering wheels (Recurrent).

3. Navigate to fast chargers using the car's own navigation

Many EVs automatically warm the battery before a fast-charging stop when you set the charger as your destination in the built-in navigation. A warm battery charges faster. Recurrent recommends this for winter fast charging (Recurrent). Check your manual to see whether your car offers battery preconditioning.

4. Charge soon after driving

BYD's Australian handbook advises that below 10 °C, you should charge straight after driving, while the battery is still warm (BYD handbook). Even if your manual doesn't say so, plugging in when you get home rather than the next morning means a warmer battery.

5. Park in a garage if you can

AAA suggests garage parking to help keep the cabin temperature stable (AAA).

6. Keep a bigger buffer, and plan stops

In winter, plan routes with more margin. Recurrent suggests keeping the car plugged in and storing it at around 70–80% in cold weather where your manual allows (Recurrent). Some manufacturers recommend a full charge, so check your own manual (see should you charge to 100%?).

7. Slow down a little

Higher speeds use more energy in any season. On a long winter drive, a modestly lower cruising speed can be the difference between needing another charging stop or not.

What winter does to your running costs

More energy per kilometre means a higher cost per kilometre. If your car averages 16 kWh/100 km in mild weather and uses about 20% more in winter, that's around 19–20 kWh/100 km. Try both figures in our charging cost calculator to see the difference for your tariff.

Key takeaways

  • Expect roughly 20–30% less range around freezing, and more in severe cold.
  • Heating is the biggest single factor, and heat pumps help in moderate cold.
  • Precondition while plugged in, use seat heaters, and navigate to fast chargers so the battery warms up.
  • Winter range loss is temporary, not permanent battery damage.
