On a cold morning, your EV may show less range than it did the day before. Preparing the car before departure and allowing extra time and charge for your trip can make winter driving easier. Available features and settings vary by vehicle.
Why does range drop in cold weather?
A cold battery may temporarily make some of its stored energy unavailable. Heating the cabin and battery also takes electricity, so a familiar journey can use more energy in winter. Charging speed and regenerative braking, which recovers energy as you slow down, may also be limited while the battery is cold. Tesla Model Y Owner’s Manual
Prepare the car while it is plugged in
If your EV supports scheduled departure or preconditioning, use it to prepare the cabin and battery before driving. With the car plugged in, supported systems can draw on the charging supply, helping preserve battery energy otherwise needed for heating after departure.
Check your owner’s manual: switching on cabin heating does not necessarily activate battery heating on every model. Heated seats and a heated steering wheel can help reduce cabin-heating demand while driving. Keep enough heating and demisting running to maintain clear windows and visibility.

Check battery preconditioning before fast charging
Even a powerful charger may charge a cold battery slowly. If your EV supports battery preconditioning for fast charging, activate it as the manufacturer directs. Some vehicles warm the battery when a supported fast charger is selected in the built-in navigation system. Do not assume that directions from a phone’s map app will trigger the same function.

Allow more margin for travel and parking
Before a longer journey, leave extra range and charging time in your plan and check charging stops along the route. Choose a charge target that suits the trip and your vehicle’s recommended settings.
Park indoors or under cover when possible. Heavy snow can cause charging connectors to freeze, so check their condition and return them to the designated holder after use. If ice makes connection or removal difficult, follow the vehicle and charger instructions. U.S. Department of Energy winter EV guidance
