> Unless you want to charge in negative temperatures

Doesn’t the thermal management system of the battery packs handle this?

Yes, the largest issue is that they heating isn't enabled unless it's charging or 'knows' it will be soon.

Ps: the heating is increasingly heat pump based instead of resistive.

It does, but it costs is complex, requires power and time.

It's noticeable even in climates like NZ.

There are coldgating stories about LFP. Some even reduce output and very low SOC and temperature, so you drive 60km/h in highway.

Sodium is vastly superior here and CATL is not going to be giving it away for free.
