7 Essential Cold Weather Tips for Electric Vehicle (EV) Owners

As temperatures drop, the performance of electric vehicles (EVs) can be significantly impacted by the cold, making it crucial for EV owners to adapt both their driving habits and maintenance routines. Cold weather affects battery efficiency, charging time, and overall range, which is why understanding how to optimize your EV charging and driving during winter is essential. With the right strategies, you can ensure your EV runs smoothly throughout the colder months. Here are seven essential tips to help you maximize your EV’s performance, including best practices for EV charging in cold conditions.

1. Use Your Heated Seats and Steering Wheel

One of the simplest and most effective ways to stay warm while conserving battery life is by utilizing your EV's heated seats and steering wheel. Heating the entire cabin consumes significantly more energy than these targeted heating options. By minimizing the use of the main HVAC system, you can reduce the strain on your battery and extend your range.

Pro Tip: Many EVs allow you to pre-set seat and steering wheel heating levels, making it easier to stay comfortable without sacrificing energy efficiency.

2. Preconditioning Your EV is Key

Preconditioning is a game-changer in cold weather. This feature warms up your vehicle’s interior and battery while it’s still plugged into a charger. By doing this, you can step into a cozy cabin while ensuring that your battery is at an optimal temperature for efficient operation.

Most modern EVs allow you to schedule preconditioning through their companion apps, letting you set your desired departure time. Not only does this save energy while driving, but it also improves your battery’s performance during charging and on the road.

3. Charging May Take Longer in Cold Temperatures

Cold weather slows down the chemical reactions inside your EV’s battery, which can increase charging times. Whether you’re using a Level 1, Level 2, or DC fast charger, be prepared for slower charge rates, especially if your battery is particularly cold when you plug in.

To mitigate this, try to charge your vehicle in a relatively warm location, such as a garage. Preconditioning your battery, as mentioned earlier, can also help speed up charging times. Patience is key during the winter months, as the safety measures built into EVs prioritize battery longevity over rapid charging in low temperatures.

4. Monitor Overnight Range Loss

Cold weather can reduce your EV’s range overnight, even when it’s parked. This happens because the battery management system (BMS) uses some energy to maintain a stable internal temperature. The extent of this range loss varies depending on the vehicle, battery size, and the severity of the cold.

To minimize overnight range loss:

Park in a garage or sheltered area when possible.

Use a trickle charger to keep the battery warm and maintain its state of charge.

Avoid leaving your vehicle unplugged for extended periods in freezing temperatures.

By staying vigilant and planning accordingly, you can avoid surprises when starting your EV on chilly mornings.

5. Manage Your Speed to Increase Range

Did you know that your driving speed can have an even greater impact on your range than cold weather? Research from Geotab shows that at higher speeds, the effect of aerodynamic drag becomes more pronounced, especially in larger vehicles. This means driving faster not only depletes your battery more quickly but also exacerbates the range loss caused by low temperatures.

To optimize your range:

Stick to the speed limit and avoid aggressive driving.

Use cruise control when possible to maintain a steady pace.

Be mindful of regenerative braking settings, which can help recharge your battery while slowing down.

Not only does managing your speed improve your EV’s efficiency, but it also ensures safer driving during winter conditions.

6. Keep Your Battery’s State of Charge (SoC) Above 20%

In cold weather, EV batteries reserve a portion of their energy to keep themselves warm. This percentage varies by vehicle but generally increases as temperatures drop. To avoid running out of usable charge, aim to keep your battery’s SoC above 20%.

Driving with a low state of charge in winter can lead to several issues:

Slower acceleration and reduced performance.

Increased risk of not reaching your destination.

Potential difficulty in starting the vehicle.

Check your owner’s manual for specific recommendations regarding your EV model, but maintaining a higher charge level is a good rule of thumb during the winter season.

7. Park in a Garage (If You Can)

Parking your EV in a garage or other sheltered area can make a significant difference in cold weather. Even an unheated garage provides protection from wind and extreme temperatures, which can help preserve your battery's charge and reduce overnight range loss.

If a garage isn’t available, consider investing in a weather-resistant EV cover to insulate your vehicle. Some owners also use portable heaters designed for outdoor vehicles to maintain a moderate temperature around their car. While these solutions aren’t as effective as indoor parking, they can still provide noticeable benefits.
