Charging an electric car in winter at minus temperatures

Charging an electric car during the winter months can present some challenges, especially when temperatures drop below zero. Here are our top tips and advice to ensure your electric car works optimally and charges as smoothly as possible, even in sub-zero temperatures.

Does the cold affect the charging of my electric car?

In low temperatures, the battery chemistry of electric cars can be affected. This can lead to longer charging times and higher energy consumption for heating. Understanding the following factors will help you plan and optimize your charging on cold days:

1. Preheat the car while it is plugged in

Before heading out, use your car's pre-heating function while it is still plugged into the charger. This will save battery capacity while driving and provide a comfortable start in a heated car. Many modern electric cars, such as Tesla, allow you to schedule preheating via an app or the car's display.

2. Use a charging station with higher power

In cold conditions, fast chargers (DC chargers) can be more efficient. If possible, choose a higher power charging station and avoid slow charging overnight outdoors in extreme cold.

3. Charge more often

As batteries can lose capacity faster in the cold, it is good to charge your car more often than usual. A nearly empty battery takes longer to warm up and charge, so try to keep the charge level above 20%.

4. Park and charge indoors

The cold affects battery performance most when the car is turned off. If possible, park your car in a garage or a place protected from extreme cold. This will both improve charging efficiency and protect the car from snow and ice. Specifically avoid leaving your car outside in extreme cold with a low battery.

5. Plan for longer journeys

For longer journeys during winter, it is important to check the availability of charging stations along the way and allow extra time to charge. Always keep an eye on battery consumption, as it increases with the use of heating and defrosting.

Charging your electric car in sub-zero temperatures requires a bit more planning and thought, but with these tips you can ensure your car runs smoothly all winter long. By keeping the battery warm, charging more often and taking advantage of your car's smart features, you can enjoy your electric car whatever the weather.
