Charging Electric Cars in Cold Weather: Tips and Information
You’ve probably heard that electric car charging in winter is fraught with problems, such as a longer charging time and potential battery deterioration. But are those claims true, and, if so, what can be done about it?
This article will delve into how cold weather affects electric vehicles and gives you some invaluable suggestions for EV charging in the colder seasons.
How does cold weather affect electric cars?
Sadly, it is not a myth that electric cars do not recharge efficiently in cold weather. Let’s delve into why this is.
The lithium-ion batteries in your electric car generally prefer temperatures between 15°C and 35°C. So, when the outdoor temperature falls below this ideal range, you’ll notice that you need longer charging periods. In ideal conditions, and when using a Level 2 charger, your car should be fully charged in a few hours. However, when the weather takes a turn, it may take all night.
Further to these issues, the colder temperatures slow down the chemical and physical reactions within your vehicles’ batteries, resulting in a reduced capacity to store and distribute that energy effectively. Consequently, you might experience a decrease in mileage by approximately 15% to 20%.
In colder seasons, the less-than-ideal temperatures coupled with slowed chemical reactions can cause longer-lasting effects. EV batteries can deteriorate quicker when exposed to prolonged low temperatures, which can then, in turn, lead to further problems beyond the winter, such as overheating.
Thankfully, to avoid the EV not charging in cold weather, most modern electric cars have a sophisticated management system for EV charging in winter. This system naturally guards against misuse and damage to the batteries, meaning that you can rest easy knowing that your electric car is designed to protect and extend its battery life as much as possible.
How to protect your car’s battery life in cold weather conditions
If you are still concerned about your EV, then we have outlined some key things you can do to help improve your car’s battery life. Maintaining and charging electric cars in cold weather correctly will help you get more miles out of your vehicle.
Pre-condition the batteries
This is the first step you should take before charging your electric car in cold weather. Pre-conditioning refers to the process of heating or cooling your EV battery pack to bring it within the ideal temperature range. This step will also help you optimise its efficiency and performance.
You can also take advantage of your car’s battery management system as this will help your EV charging in cold weather. All you need to do is set a specific departure time. The purpose of this is so that the system can pre-condition the EV batteries 2 to 3 hours before you start the charging session.
Charge your EV indoors
If it is too cold outside, it is a good idea to charge your electric car in some form of enclosed structure, such as a garage. Charging indoors will help you take advantage of the controlled and warmer environment - your garage will always be warmer than the driveway, even if it doesn’t always feel like it! Charging your car there can help to ensure optimal charging conditions and prolong the battery’s efficiency.
Invest in a reliable home charging station
The key to installing the ideal charging station for your home is to do your research. Choose an installer who has extensive experience in installing EV home chargers. You may also like to ask for referrals from people you trust, or to check reviews from previous customers online.
Monitor the charging speed
So, now you know that your electric car may take longer to fully charge in cold temperatures. To help you work around this, plan some contingency into your charging times and make sure to monitor the charging speed of the battery. By actively monitoring the charging speed, you can be more aware of any changes in the speed, and therefore can mitigate appropriately.
Look for the best EV charger for cold weather
You should always choose an electric vehicle charger that is specifically designed for cold-weather charging. Ideally, look for one with a temperature operating range below the point of freezing (0°C or 32°F). It should also match your car’s charging speed and power level requirements. If you want to spend a little more on your four-wheeled bestie, consider EV chargers with smart features, such as mobile app connectivity.
Charging your EV in cold weather: plan ahead efficiently
If you find your electric car isn’t charging in cold weather, don’t panic. Follow our tips and make sure to always plan ahead.
Furthermore, if you are considering buying a new electric vehicle in the future, then the matter of deteriorating batteries will be even less of an issue. The EV industry is dedicated to creating batteries that can withstand low temperatures and implementing innovative measures to maximise your car’s efficiency in demanding climates.
