Why is the battery life of the BMW iX shorter during colder months?

I recently noticed that the battery life of my BMW iX seems to decrease during colder months. Why is this happening and is there anything I can do to prolong the battery life during these months?

During colder months, the battery chemicals in electric cars tend to slow down, leading to a decrease in performance and range. One way to combat this is by pre-warming your car before starting your journey. This can help to warm up the battery pack, which can improve performance and increase battery life.

Another factor that can affect your battery life during colder months is the use of heating and other electrical systems in the car. These can put a strain on the battery and decrease its overall life. To help preserve battery life, you can try to limit the use of these systems or use them sparingly.

Additionally, make sure to keep your car battery charged regularly during the colder months. Just like with a phone battery, the more frequently you charge it, the better it will perform. So try to charge your car battery overnight or whenever you have the opportunity to do so.
