So they already come with a BMS. Create a MetaBMS. The BMS of the cell pack doesn't care if a car requests energy between 0 and max and a BMS doesn't care either if it gets 0-100 kWh. My car can easily charge from a household plug up to fast charger. My car consumes very random amounts of energy while i drive.
