First, cold weather will make the electrolyte inside the battery more viscous, thereby reducing the battery charging rate. In addition, low temperatures will increase the internal resistance of the battery, further extending the charging time.
In the cold winter, if you need to travel, please pay attention to the following 4 points
The optimal ambient temperature for charging is 25 degrees Celsius (°C) = 77 degrees Fahrenheit (°F), which is impossible to achieve in the winter in the north of most countries, so try to park or charge in a higher temperature environment, such as underground parking lots, closed garages, etc. If there are no conditions, it is best to choose to charge on a sunny day in winter, which is conducive to improving battery activity, reducing the loss of cruising range, improving charging efficiency, and saving time.
In winter, fuel vehicles should be warmed up before driving. This "preheating" also applies to the batteries of pure electric vehicles. Due to the low temperature in winter, especially the temperature at night, even if the battery is fully charged the night before, you will find that the battery has "run away" some of the power after driving it overnight.
For electric vehicles with integrated applications. You can heat the cabin of your electric vehicle before you set off. It's a win-win situation: you get a more comfortable cabin, and you can heat the battery to a more efficient temperature.
In fact, the longer charging time of pure electric vehicles in winter is also due to the addition of a battery preheating time. (When the battery cell is below 0°C, the system will first heat the battery cell, and when its temperature reaches 5 degrees Celsius (°C) = 41 degrees Fahrenheit (°F)
, it will start charging the vehicle.)
Charge as you use, that is, charge the pure electric vehicle immediately after use. *Please note that the battery's state of charge (SoC) should be kept above 20% when using it. This is because the battery temperature is relatively high after the vehicle is used. Charging at this time can reduce the time to heat the battery and improve charging efficiency.
Driving a pure electric vehicle in winter generally reduces the range by 10%～20%, which is about 15 (km) =9.4 (mi)-30 (km) =18.7 (mi). So plan your trip well before you go and leave yourself some extra room to avoid running out of juice halfway through your EV and not being able to find a place to charge.
Finally, your EV will lose range in cold weather because your battery will use extra energy to keep itself warm. Long-term exposure to extremely cold temperatures will not degrade the performance of your EV battery. Once the temperature rises, your EV's range will return to normal.
