I don't think 800V is a competitive advantage yet. Hyundai has the fastest charging EV at the moment, but it still doesn't use 350kW and it's only a few minutes faster than a Tesla for 10-80. Plus, it's not at all clear that they won't be forced to dial the number down -- Teslas used to charge a bit faster but it was really messing with the batteries, and Hyundai may be about to hit a similar problem. The C rate they'll allowing their batteries to charge at is pretty high.
