I had just been wondering whether we would eventually end up with a (very anemic) DC charger at home. It would save weight and complexity in the car, and would enable you to efficiently charge with a dc-dc converter from a battery pack or solar at home, rather than lots of DC-AC-DC converters.

As far as I understand it a charging station can limit the charging speed to whatever it likes. The car may want 250 kW, but the charging station may have no more than 50 kW available. When charged through a built-in inverter it will limit to 7 kW; or whatever the mains supply can deliver?

Depending on the vehcile excessive DC fast charging can trigger a derate, particularly in NMC packs. Tesla did this with the Model S. I assume the cab is LFP, so maybe it's not a big deal.
