Tips on How to Prevent Battery Degradation and Maximize Range in Cold Weather

If you own an electric car, you may have noticed that your battery performance and range decrease in cold weather. This is because electric car batteries and cold weather don’t mix well. The lower the temperature, the higher the internal resistance of the battery, which slows down the chemical reactions that generate electricity. In this article, we will discuss some tips on how to prevent battery degradation and maximize range in cold weather.

How Does Cold Weather Affect Electric Car Batteries?

According to a study by AAA, electric car battery performance in cold weather can drop by an average of 41% when the temperature falls to 20 degrees Fahrenheit and the heater is on. This means that your electric car will have less driving range, longer charging times, and reduced regenerative braking efficiency.

Some of the factors that contribute to this loss of performance are: 

  • The battery needs more energy to maintain its optimal operating temperature, which is between 40 and 115 degrees Fahrenheit.
  • The heater, defroster, and other accessories consume more energy to keep the cabin warm and comfortable.
  • The electrolyte fluid inside the battery becomes more viscous, which hampers the flow of ions between the electrodes.
  • The regenerative braking system, which recovers kinetic energy and converts it into electricity, works less effectively in cold weather. 

How to Prevent Battery Degradation and Maximize Range in Cold Weather?

Fortunately, there are some steps you can take to minimize the impact of cold weather on your electric car battery life and range. Here are some of them: 

  • Avoid letting your battery get below 20% charge, as this can damage the cells and reduce their capacity over time.
  • Plug in your car whenever possible, especially overnight or when parked for a long time. This will help keep the battery warm and reduce the energy needed to heat it up when you start driving.
  • Preheat your car while it is still plugged in, using a timer or a remote app. This will save energy by warming up the cabin and the battery before you hit the road.
  • Use seat heaters and steering wheel heaters instead of blasting the cabin heater, as they consume less energy and provide more comfort.
  • Drive smoothly and avoid sudden acceleration or braking, as this will reduce the stress on the battery and improve your efficiency.
  • Plan your trips carefully and use navigation apps that show you the nearest charging stations along your route. This will help you avoid running out of juice or having to wait for a long time at a busy charger.


Cold weather can have a negative effect on electric car batteries, but it doesn’t mean you have to give up on driving green.
