How much does cold weather reduce EV range?

At 0°C expect 15-20% less range; at -10°C expect 25-35% less. Extreme cold below -20°C can cut range by 40-50% in some EVs, especially without a heat pump.

Does hot weather affect EV range?

Yes, but less than cold. Air conditioning can cost 5-10% range in extreme heat, and very high battery temperatures slightly reduce charging speed and efficiency.

What is the ideal temperature for EV range?

20-25°C is the sweet spot. In this range, batteries are efficient, no cabin heating or cooling is needed, and EVs often exceed their official range.

How can I reduce cold-weather range loss?

Precondition while plugged in, use seat heaters instead of cabin heat, park in a garage, and use a heat pump if your car has one. These can recover 10-20% of winter range.

Winter range recovery tips

Precondition plugged in. Heat the cabin before driving — costs grid power, not range.
Use seat & steering heaters. Far cheaper than heating all the air.
Park in a garage. Keeps the battery warmer overnight.
Drive with the heat pump on eco. Newer EVs manage cold-weather efficiency well.

How it's calculated

20-25°C is optimal — range at or above official.
0°C: ~15-20% loss with a heat pump, ~25% without.
-10°C: ~25-30% loss, rising to 35-40% on short trips.
Heat: >30°C AC usage adds ~5-8% loss.
Based on AAA and real-world cold-weather EV tests.
