Some cars have heat pumps for cab heating.

The better ones also have complete pumped thermal management systems for
the batteries to keep them within temperature spec. Needless to say that
also consumes additional power.


only when charging (there is no airflow).


No, for use when driving as well. They are called Battery Thermal
Management Systems. In very cold conditions they need to heat the
battery, not cool it.



Cold like Siberia/USA, not the UK.


I see you have not read the link *you* posted earlier then...

Any time you charge or draw current from the battery and its outside a
defined temperature range you will get accelerated battery ageing and
hence loss of capacity and possibly reduced peek current delivery.
