Why does my BMW i3 have a shorter range when using the heat or AC?

I've noticed that when I have the heat or AC on in my BMW i3, the range seems to decrease significantly. Is there a way to improve the range with the heat or AC on?

The use of the heat or AC in your BMW i3 requires energy from the battery, which can drain the range. To improve the range, try to pre-condition your vehicle while it is still plugged in before driving. This will use external power to heat or cool the car, rather than draining the battery while on the road.

You can also try using the Eco Pro mode in your i3, which will reduce the amount of energy used for heating and cooling. This should help improve the range while still providing a comfortable temperature in the car.
