EV winter range: what to really expect, and how to reduce the losses

Every EV goes less far in winter. The good news is that the loss is temporary and predictable, and you can reduce it a lot. The data below comes from a large real-world fleet study and an independent UK test. We say where each figure comes from so you can judge how well it fits your own driving.

What the data says

Real-world fleet data: Recurrent (2025/26)

Recurrent analysed real-world driving data from more than 30,000 vehicles in the US, covering 34 popular models. It found:

• At 0°C (32°F), EVs kept on average 78% of their range in ideal temperatures, a loss of about 22%.
• At −7°C (20°F), they kept on average 70%.
• The best model kept 88% at 0°C. The worst kept 69%.
• Cars with a heat pump kept about 10% more range at 0°C.

UK winter test: What Car? (December 2024)

What Car? drove 12 EVs until they ran out of charge on a test track in Bedfordshire. The cars were left outside overnight at 6–10°C and driven at 10–11°C in wind and rain, on a route weighted towards steady 50 and 70 mph driving. Real ranges came in 21% to 38% below the official WLTP figures. Some of that shortfall is due to motorway speeds, not just the cold. In an earlier comparison of three models tested in both summer (24–29°C) and winter, range was on average 18% shorter in winter. The Tesla Model Y lost the least (11.8%) and the BMW i4 the most (21.6%).

What that means for a UK winter

UK winters are usually milder than Recurrent's 0°C reference point. Using the Met Office's UK mean-temperature series, the average for December–February over 1991–2020 works out at about 4°C. So on a typical winter day, many drivers will see a loss somewhere between the "mild winter" What Car? results and Recurrent's freezing-point figure. Expect a bigger loss on frosty mornings, short trips and fast motorway runs.

Rough winter range from your summer range

If you apply Recurrent's average retention figures to a few typical ranges, you get the table below. This is a rule of thumb, not a prediction for your car.

Why EVs lose range in the cold

• Heating the cabin. This is the biggest factor. A petrol engine wastes lots of heat, which warms the cabin for free. An efficient electric motor makes very little waste heat, so the car has to use battery energy to keep you warm.
• Battery chemistry. Chemical reactions inside the battery slow down in the cold, which reduces the power and energy available until the pack warms up.
• Less regenerative braking. A cold battery cannot accept charge as quickly, so the car may limit regenerative braking and recover less energy.
• Short trips. Every cold start means warming the cabin and battery again. Lots of short journeys usually hurt efficiency more than one long one.
• Wet roads and headwinds. These add resistance in any car. They are just more noticeable when you are watching a range estimate.

How to reduce winter losses

• Precondition while plugged in. Recurrent and Energy Saving Trust both recommend warming the car while it is still charging, using the app or a departure-time setting. The heat then comes from the mains, not the battery, and keeping a car warm takes less energy than warming it from cold.
• Use seat and steering-wheel heaters. They warm you directly and use less energy than heating all the air in the cabin. Turn the cabin temperature down a little once you are moving.
• Keep it plugged in when you can. Recurrent suggests leaving the car plugged in with a 70–80% charge limit, so it can use mains power to look after the battery instead of using up its charge.
• Navigate to rapid chargers in the car. Many newer EVs warm the battery automatically when you set a rapid charger as the destination, which shortens the charging stop.
• Ease off on the motorway. Speed costs range in any season. Energy Saving Trust's eco-driving advice is to watch your speed and anticipate the road to avoid harsh acceleration and braking.
• Check tyre pressures. Cold air lowers tyre pressure, and under-inflated tyres waste energy. Check against the figures in your handbook.
• Park in a garage if you have one. A sheltered car starts warmer and needs less energy to heat.

Rapid charging in winter

A cold battery charges more slowly, because the car limits charging power to protect it. Recurrent warns drivers to expect longer stops until the battery has warmed up. Arriving at a charger after a long drive, or with the battery preconditioned, makes a big difference. For long trips, plan a bit more margin between stops. Our road trip charging guide has more on this.

What winter does to running costs

Lower efficiency means more kWh per mile, so winter miles cost more. That is true of petrol cars too, which Recurrent points out also lose efficiency in the cold. As a rough guide, a car that averages 4.0 mi/kWh in mild weather and follows Recurrent's 0°C average would manage nearer 3.1 mi/kWh in freezing weather. To see the effect, lower the "EV efficiency" figure in the EV Cost Comparison to a winter value, or use a year-round average from your trip computer. Charging off-peak softens the blow: see our off-peak tariff guide.

Is winter range loss permanent?

No. Recurrent says cold-weather range loss is temporary and does no long-term harm to the battery. Range comes back as temperatures rise. If your range is still low in summer, that is a separate battery health question.
