Winter Electric Car Range Calculator

Compare normal-weather range with a transparent cold-weather scenario.

Your vehicle, your numbers

Example numbers are prefilled. Replace them with your vehicle data and local prices. Currency changes the label, not the exchange rate.

kWh
Where do I find this?

Match usable/net capacity to the exact pack and configuration. Check whether this field asks for original or current capacity; gross capacity is different.

kWh/100 km
Use battery-side driving consumption, not energy from your electricity bill.
Where do I find this?

Find recent driving consumption in the vehicle’s trip or energy display. Record the period and units. A charger receipt includes losses.

km
If supplied, this becomes the range baseline instead of capacity ÷ consumption.
Where do I find this?

Use your own normal-weather range for comparable trips. Leave blank to derive a baseline from capacity and consumption.

°C
Where do I find this?

Use the expected outside temperature. It records context; it does not automatically set a range penalty.

Editable planning assumption; not a model-specific measured prediction.
Where do I find this?

Choose the lower assumed winter range loss. This is a scenario input, not a universal temperature-to-range rule.

%
Where do I find this?

Choose the higher assumed winter range loss. It must be at least the lower scenario.

Your results

Transparent by design

A clearer picture starts here.

Review the example inputs, then calculate. We show the assumptions alongside your result.

Why is this an estimate?

Temperature, cabin and battery heating, wind, tyres, road conditions and speed all matter. The 15–35% starting band is an illustrative scenario you should replace with observations for the vehicle.

Read our methodology

EVVerity estimates are informational and are not a substitute for a professional battery diagnostic or pre-purchase vehicle inspection.

See how the calculation works

Cold-weather range = normal-weather range × (1 − range-loss scenario ÷ 100).

Temperature, cabin and battery heating, wind, tyres, road conditions and speed all matter. The 15–35% starting band is an illustrative scenario you should replace with observations for the vehicle.

Example: choose both ends of the cold-weather scenario

For a normal-weather range of 300 km, selected range losses of 15–35% produce 195–255 km. The calculator sorts the range from the more demanding scenario to the less demanding one. It does not infer those losses from temperature.

Where to get useful inputs

  • Use a normal-weather baseline for comparable roads and speeds.
  • Choose the loss assumptions from relevant observations where available.
  • Heating, road and driving selections document the scenario; they do not silently add penalties.
Is winter range loss the same as permanent battery degradation?

No. A change in energy consumption or operating conditions can reduce range without establishing permanent capacity loss. Use comparable battery evidence to assess degradation.

Methodology, assumptions & confidence →

Separate a seasonal scenario from a battery test

Original EVVerity worked scenario. Inputs are illustrative, not measured vehicle results or market prices.

  1. Enter normal-weather range 300 km, lower loss 15% and upper loss 35%. The result is 195–255 km.
  2. Compare a proposed 220 km journey with both ends: it fits the less demanding assumption but exceeds the more demanding one.
  3. Confirm whether the 300 km baseline already includes your desired reserve. This tool applies losses to the range you enter; it does not add another reserve.

What the result helps you decide

Use the Range Calculator when you need a specific starting charge and arrival reserve. Do not deduct winter losses again if your baseline already comes from the same cold-weather conditions.
