Why is the battery range of the Audi e-Tron reduced in cold weather?

I have noticed that the battery range of my Audi e-Tron is significantly decreased when driving in cold weather. Why is this happening? Is there a way to improve the range in colder temperatures?

The decrease in battery range in cold weather is due to the chemical reactions within the battery being less efficient in lower temperatures. To improve the range, try preheating the car while it is plugged in before driving.

One way to improve the battery range in cold weather is to use the heated seats instead of turning up the heat in the car. This will help conserve energy and improve overall range.

As a general rule of thumb, you can expect a decrease of about 20% in battery range for every 20 degrees decrease in temperature. To combat this, try using a battery warmer or insulating the battery to help maintain its efficiency in colder temperatures.
