Why is the range of the Audi e-Tron affected by weather conditions?

I've noticed that my Audi e-Tron's range decreases in cold weather. Why is this and is there anything I can do to improve it?

The Audi e-Tron uses a battery to power its electric motors, and batteries are sensitive to temperature changes. In cold weather, the battery's performance decreases, resulting in a decrease in range.

To improve the range in cold weather, preheat your car while it's still plugged in. This will warm up the battery and improve its performance.
