How It Works

Cold weather is the biggest enemy of EV range. Unlike gas engines that generate waste heat for cabin warming, EVs must use battery energy for heating. At 25°F, expect to lose 25-35% of your normal range — and at 0°F, losses can reach 40-50%. Heat pumps make a significant difference: they move heat rather than generating it, reducing heating energy use by 30% or more. Preconditioning (warming the cabin and battery while still plugged in) is one of the best strategies because it uses grid power instead of battery power. Other winter tips include using seat and steering wheel heaters (which use far less energy than cabin heat), keeping tires properly inflated (cold weather drops pressure), and parking in a garage when possible. Most modern EVs handle winter well with a little planning — the key is adjusting your expectations and charge routine for the season.
