So the battery doesn't gain charge/range as it warms up, but on cold days/climates when the battery is cold soaked vs in a warm garage or just finishing a charge, there is some battery capacity/range you can't get to until it warms up. The BMS controls this. This is why when the battery is cold your regen will be reduced.
The cold battery can not charge as fast or discharge as fast, the BMS protects it.
This is why on a Tesla if you are headed to a Supercharger and the car knows it (you've selected it on the navigation) even on a moderate day it will still start to warm the battery so it can accept a faster charge. If you pull up with a cold battery you will not get a maximum charge
