You can put a bigass boost converter in the car if you need to bump the voltage up to 900V.Existing Superchargers don't need to be, do they? Correct me if I am wrong, but a 900v system would still be able to be charged by existing DC fast chargers without changing them.
Porsche Taycan has an 800v system and it can charge at most CCS chargers even if they don't support 800v.
I assume a 900v system (if true) would be driven by cost gains (at volume) and a potential increased charging speed would just be an added benefit.
But it comes with a tradeoff: a bigass boost converter costs money, mass, and volume on every car.
It's much better to put a bigass boost converter offboard, if you can, where mass & volume don't matter so much.
