Why does the Audi e-Tron's range decrease in cold weather?

I've noticed that my Audi e-Tron's range decreases significantly in cold weather. What causes this and how can I maximize my EV's range during the winter months?

The decrease in range during cold weather is primarily due to the increased energy required to heat the cabin and battery. To improve your e-Tron's range, try preheating the car while it's still plugged in and reducing the use of heated seats and climate control while driving.

Cold weather causes a decrease in battery efficiency, resulting in a smaller usable capacity. To counteract this, try keeping your e-Tron plugged in whenever possible and avoid letting the battery drop below 20% charge. This will help preserve its overall battery life and range.
