EV heating and range: How many miles does a warm cabin really cost?

First, two pieces of news. The good one: you do not have to freeze in an EV, and the cabin can even warm up faster than in a combustion-engine car. In the ADAC climate chamber, almost all test vehicles were already blowing air at nearly 40°C from the vent next to the steering wheel after five minutes. The reality check: if you drive lots of short journeys in winter, heating can have a noticeable impact on your EV’s range. Here are the measurements, the physics behind them and the practical ways you can reduce the effect.

EV heating and range: what the measurements show

Two things draw energy from the battery in winter. First, the cabin, including the windows, seats and steering wheel. Second, the battery itself: according to the ADAC, its ideal temperature range is between 20°C and 40°C. Bringing a cold battery weighing several hundred kilograms back up to temperature requires a considerable amount of energy. How much this affects consumption depends primarily on one factor: the length of your journey.

Short trips at -7°C: the worst-case scenario

Green NCAP puts vehicles through a 23-kilometre commuter route after they have spent a night at -7°C. The result is striking: compared with testing at 23°C, average consumption increased by 70%, with individual models recording rises of between 38% and 107%. Under these conditions, range fell by around 40% on average.

Longer journeys at 0°C: a much easier picture

On 100-kilometre test drives at 0°C, the figures look considerably better. The VW ID.3 used just over 30% more electricity than at 20°C, while the Renault Zoe and Peugeot e-208 each used 21% more. In the ADAC long-term test on public roads, winter consumption increased by between 25% and 31%. The reason is simple: once the cabin has warmed up, maintaining its temperature requires far less energy than heating it from cold.

Motorway driving in winter: 14 family EVs put to the test

In January 2026, the ADAC sent 14 family-friendly electric vehicles on a simulated journey from Munich to Berlin at 0°C, with the heating set between 20°C and 23°C. None completed the 582-kilometre route without stopping, and most needed two charging stops. On average, consumption was 57% higher than the WLTP figure. On the motorway, however, aerodynamic drag is a major driver of energy consumption – not heating alone.

Heating and energy consumption: how many kilowatt-hours does warmth use?

So how much energy does heating actually require? The ADAC measured seven models at -10°C in a climate chamber. To heat the cabin to 20°C and maintain that temperature, the Hyundai Kona Electric and Fiat 500e each required 1.5 kWh, the Tesla Model Y 1.6 kWh, the Renault Zoe 1.8 kWh, the VW e-Up and BMW iX 2.0 kWh each, and the VW ID.3 2.3 kWh. Once the cabin is warm, a heating output of between 1.5 and 2 kW is sufficient to maintain the temperature.

An ADAC overnight test at temperatures between -9°C and -14°C shows what this means in an extreme situation. A Renault Zoe and VW e-up remained switched on for twelve hours with a cabin temperature of 22°C and heated seats activated. By the end of the test, the Zoe had used around 70% of its battery and the e-up around 80%. Extrapolated from these results, you could have stayed warm in a traffic jam for up to 17 hours in the Zoe and 15 hours in the e-up.

Example calculation: how much range does one hour of heating cost?

Now for a more tangible example. Assume your EV consumes 17 kWh per 100 kilometres while driving. In that case, the measured heating consumption of 1.5 to 2.3 kWh per hour corresponds to roughly nine to 14 kilometres of driving range for every hour of heating at -10°C. At 2 kWh, that is just under 12 kilometres.

This gives us a useful answer to the question of how much EV range heating can consume. One point is important, though: these figures come from stationary testing. In everyday driving, the initial energy required to warm up both the cabin and battery also has to be added. It is this initial demand that makes short journeys particularly energy-intensive.

Why heating has a bigger impact in the city

Heating consumes energy per hour, not per kilometre. That leads to a simple but often overlooked calculation based on 2 kW of heating power:

• At an average speed of 30 km/h in urban traffic, heating uses around 6.7 kWh per 100 kilometres
• At 120 km/h on the motorway, heating accounts for only around 1.7 kWh per 100 kilometres
• Based on driving consumption of 17 kWh/100 km, heating therefore increases energy demand by around 40% in the city but only around 10% on the motorway

This approximation helps explain why the Green NCAP commuter test produces such dramatic results while longer journeys are affected less severely. When you travel slowly, you simply spend more time in a heated car for every kilometre driven. Your winter range therefore depends not only on the outside temperature, but also on how and where you drive.

Small features, big impact: heated seats and steering wheels

According to the ADAC, an electric auxiliary heater can draw up to 2,000 watts. A heated seat uses around 100 watts, while a heated steering wheel requires roughly 50 watts. In purely mathematical terms, one hour of auxiliary heating therefore consumes as much energy as 20 hours of seat heating. Heating your body directly is simply the most energy-efficient way to stay warm in the car.

EV heat pumps: how much extra range do they really provide?

According to the ADAC, a conventional PTC heater works much like a fan heater, converting roughly one kilowatt-hour of electricity into one kilowatt-hour of heat. A heat pump does not generate heat directly. Instead, it extracts heat from the surrounding air. Under favourable conditions, this allows it to produce three to four units of heat from one unit of electricity.

But how much of that advantage remains in winter? Whether a heat pump is worthwhile in an EV depends heavily on the temperature outside.

What speaks in favour of a heat pump

• US analytics company Recurrent analysed data from more than 18,000 vehicles during winter 2024/25. EVs equipped with a heat pump retained an average of 83% of their range in freezing conditions, compared with just 75% for models without one.
• Around freezing point, Recurrent reports a range advantage of between 8% and 10%.
• In the 2026 ADAC winter test, all competitive vehicles were equipped with a heat pump, and the technology is now standard on many models.

Where heat pumps reach their limits

• At -10°C, the ADAC found no significant efficiency advantage in its climate chamber. The VW ID.3, BMW iX, Renault Zoe and Tesla Model Y were equipped with heat pumps but consumed similar amounts of energy to the VW e-Up and Fiat 500e with conventional heating systems.
• According to electrive.net, heat pumps can only make limited use of their efficiency advantage on short journeys, while they perform considerably better over longer distances.

For Germany, that is actually good news. The ADAC deliberately chose 0°C for its winter test because this temperature is slightly below the German winter average. It is precisely in this mild freezing range that heat pumps work particularly well.

That makes a heat pump a genuine advantage for range during a typical German winter. If winter range is important to you, the ADAC considers the investment worthwhile.

EV heating not getting warm? The most common reasons

Your heating is not getting warm even though you set the temperature to 24°C some time ago? Before assuming something is broken, it is worth checking a few things. When an EV does not heat up as expected, the behaviour is often intentional.

1. The manufacturer’s heating strategy

Every manufacturer manages cabin heating differently. In Green NCAP testing, the BYD Atto 3 and Renault Kangoo remained at around 17°C despite being set to 23°C, while the Tesla Model 3 and Model S reached temperatures above 30°C.

According to the ADAC, some vehicles deliberately do not heat the cabin to the selected temperature in order to reduce energy consumption. In climate-chamber testing, the Renault Zoe reached a maximum average cabin temperature of only 14°C, the VW e-Up 10°C and the Tesla Model Y 15°C – even after 40 minutes.

The ADAC attributes these results partly to the heating control strategy and partly to the number and positioning of air vents. The BMW iX, by contrast, was fully warmed up after 12.5 minutes thanks in part to additional vents in the B-pillars.

2. Eco mode limits the heating

According to electrive.net, virtually every electric vehicle has an Eco mode that limits heating output. AUTO BILD also points out that energy-saving modes often reduce the effectiveness of both heating and air conditioning.

Some models allow you to configure the climate control independently of the driving mode, so it is worth checking your vehicle manual.

3. Severe frost and short journeys

At very low temperatures, heat pumps become less effective, as explained above. Many systems therefore combine a heat pump with an electric heater, as automotive supplier MAHLE describes.

Time is another factor. At -10°C, half of the vehicles in the ADAC test took more than 30 minutes to warm their cabins to 20°C. After being parked, the VW e-Up cooled to 5°C within 30 minutes, while the better-insulated BMW iX still maintained around 10°C.

If you make lots of short journeys with breaks in between, the car may simply never have enough time to become properly warm.

Your quick check

Your EV heating is not getting warm? Work through these points in order:

1. Set the driving and climate modes to Normal rather than Eco.
2. Use automatic climate control and select a slightly higher target temperature.
3. Check whether a zone-based or driver-only energy-saving function is active.
4. Preheat the vehicle while connected to the grid so you start your journey with a warm cabin.
5. If the air remains cold even during longer journeys in Normal mode, have the vehicle checked by a qualified workshop.

How to get more range from every charge in winter

The ADAC recommends several practical measures that can noticeably reduce the effect of heating on EV range in everyday winter driving:

• Preheat while connected to the grid: If the car is plugged into a wallbox or charging station, the energy comes from the grid rather than the battery. Around 15 minutes may be sufficient, depending on the vehicle.
• Use surface heating: Heated seats, steering wheels and windows are more efficient than heating the entire cabin air.
• Choose a moderate temperature: A slightly lower cabin temperature – and heating only the driver’s area where possible – reduces consumption.
• Use recirculation strategically: Recirculation allows the cabin to warm up more quickly.
• Use a garage: A sheltered parking space prevents the battery and cabin from cooling down as severely.
• Combine journeys: Several short trips with long stops in between require particularly large amounts of heating energy.
• Charge after driving: A warm battery can accept more power during fast charging than a cold one.

One factor always takes priority: safety. Clear, mist-free windows and good visibility are not areas where you should try to save energy.

We are here for you in winter too: why your charging stop matters even more

Cold weather does not just reduce range. It can also slow down charging. If the battery temperature falls outside its ideal operating window, the battery management system reduces charging power. That is why the ADAC and electrive.net recommend fast charging directly after driving, while the battery is still warm.

You can find out how to bring the battery to the right temperature intentionally in our guide to EV preconditioning.

This is exactly where JOLT fits into your winter routine. Our ultra-fast chargers are located right in the city, where you are already shopping, grabbing a coffee or working. With charging power of up to 320 kW, you can add energy for up to 200 kilometres of range in around ten minutes. How quickly your individual vehicle charges is determined by its battery management system.

Our stations are available 24/7 and, thanks to integrated battery storage, they can provide ultra-fast charging without costly grid extensions.

Frequently asked questions

How much EV range does heating use per hour?

According to ADAC measurements at -10°C, EV heating consumption is around 1.5 to 2.3 kWh per hour. This is the amount of energy required to keep the cabin warm. Assuming driving consumption of 17 kWh/100 km, that corresponds to approximately nine to 14 kilometres of range. The energy required for the initial warm-up and battery heating comes on top of this.

Is a heat pump worth it in an electric car?

For many drivers, yes. Fleet data from Recurrent shows that EVs equipped with heat pumps retained an average of 83% of their range in freezing conditions, compared with 75% for vehicles without one. At -10°C and below, however, the advantage becomes significantly smaller.

Are heated seats really more efficient?

Yes. According to the ADAC, a heated seat uses around 100 watts and a heated steering wheel around 50 watts. An electric auxiliary heater can draw up to 2,000 watts.

Could I freeze in an EV during a winter traffic jam?

It is unlikely. In an ADAC overnight test at temperatures as low as -14°C, a Renault Zoe could theoretically have provided heating for up to 17 hours. The important condition is that the battery is not already almost empty when the traffic jam begins.
