30% of damage avoided: these simple solutions protect your car batteries from the freezing winter

Date:

Electric cars are becoming increasingly popular among drivers, and their presence on our roads continues to grow. However, when winter sets in and temperatures drop, several challenges arise.

Between reduced range, charging issues, and accelerated wear, winter can be a real test for these vehicles. But don’t worry, there are simple solutions to avoid unpleasant surprises.

Lithium-ion batteries: The first victims of the cold

One of the biggest challenges for an electric car in winter is managing its battery. Low temperatures directly impact the performance of lithium-ion batteries. The result? A significant drop in range, with losses of up to 30% depending on conditions and the model. For drivers accustomed to precisely planned daily commutes, this decrease can become a real issue. To minimize these effects, it’s recommended to preheat the battery before hitting the road. This can be done while the car is still plugged into a charging station, ensuring an optimal energy level. Another tip: use heated seats instead of the overall heating system, as the latter consumes much more energy. These small habits can make a big difference on long winter drives.

Charging cables put to the test

Another common winter issue is related to charging cables, which can be affected by freezing conditions. If water seeps into the connector—perhaps running along the cable—it can freeze and block the use of the plug. While such incidents are rare, they can be avoided with a few simple precautions. The best approach is to form a loop with the cable during charging. This way, water naturally drains toward the ground instead of accumulating near the connector. This ensures optimal functionality even in freezing temperatures. Additionally, regular maintenance of connectors and cables, especially during the colder months, can prevent many headaches. And ideally, of course, storing your electric car and charging station in a closed garage or under a shelter is the best solution, but that’s not always possible.

Accelerated wear and adjusted driving

Beyond batteries and cables, winter also tests other components of electric cars, including brakes and tires. Driving styles can exacerbate these issues, particularly with regenerative braking, which places extra demand on certain parts. Tires, too, experience faster wear, especially if the vehicle is not equipped with winter-specific models. To protect these components, it’s advisable to adopt smoother, more cautious driving in winter. By avoiding sudden braking and unnecessary accelerations, you not only reduce vehicle wear but also improve energy efficiency. Furthermore, installing winter tires, which are specially designed to provide better traction on cold, slippery roads, is a smart investment for enhanced safety.
