If you’ve been thinking about what it’s like to drive an electric vehicle (EV) this winter, you might have seen or heard some of the most common misconceptions about what cold weather does to an EV. From low batteries freezing up, to a colder drive, to less mileage, there’s lots of misinformation out there about the perils of a cold EV! Lucky, we’re here to help combat those myths.
EVs batteries don’t work in cold weather:
Most EV batteries are lithium-ion, and it is true that they are sensitive to extreme cold temperatures. However, the climate in the UK is reasonably consistent, with extreme cold weather a rare occurrence. 90% of new car sales in Norway are electric, with a quarter of all cars in EVs, and they have some of the coldest temperatures in Europe; winter averages are around -4 degrees Celsius.
Although your cars battery performance in cold temperatures is likely to drop a small amount, it depends on various factors such as your individual car, the age and the battery range. Monitoring your car range and making sure that your battery does not dip below 20% charge can help you prepare your car for cold weather conditions.
EVs can’t warm up in cold weather:
It’s true that most EV systems can be quite energy intensive, especially if you’re trying to drive and blast the heating on full on those cold winter mornings! Luckily for EV drivers, most EVs now have a feature that mean you can schedule preheating in your car before you even leave to drive. If you preheat your car whilst it is plugged in, you can preserve battery life, as your EV won’t need to tap into the battery to heat it up. You will be so happy to step into an, already defrosted, warm car and less will be drained whilst you’re driving.
EVs don’t drive well in cold weather:
EVs can perform well in cold weather, it’s just about understanding how to maximise them. The more precise control you have with EV power delivery via the accelerator pedal should mean that even icy conditions are less stressful as long as you’re careful. By pre-heating your car, making sure your car has lot of charge on it and driving it sensibly in eco-mode can help maximise battery life. Like all cars, tyres are a huge factor in how well a car can perform, so checking pressure, and if necessary, investing in winter tyres can help. Good planning can help you avoid all the misconceptions of EVs not being able to drive well in winter and enjoy more benefits of this superior technology.
Charging in cold weather damages the EV:
All cars need consideration in inclement weather and, like we’ve mentioned above, the lithium-ion in batteries can take longer to charge due to the cold. Again, this varies on how big the battery is and the range of the car. Charge becomes slower, as colder conditions can slightly slow down the chemical reactions in your battery that takes place when it charges. It’s still possible to charge in cold weather, but charging on slow chargers can help preserve the battery life for longer. It’s also recommended that batteries are kept between 20-80% in general as this can help preserve the car for longer.
So, as with all misconceptions, the truth is much easier than is generally assumed. It is completely possible to keep your EV going in cold weather and, once you’re used to it, you’ll enjoy it more than if it was petrol powered! A bit of preplanning and understanding of the battery systems can go a long way in helping you get the most out of your EV.
