> If the charger provides 800V and a minimum of 300A, the Taycan can charge from five to 80 per cent in 22.5 minutes.
Wow! That's an insanely huge amount of current. Obviously the cables would have to be very thick to reduce transmission losses, but then you'd also have to have sufficient insulation/protection at 800V!

Some CCS chargers are 400 kW:

Cars like the Lucid Air, Porsche Taycan, Porsche Taycan Cross Turismo, Audi e-tron GT, Hyundai Ioniq 5, and the Kia EV6 can take advantage of the higher voltage to get high peak charging rates.
The Lucid Air's peak charging rate is supposed to be above 300 kW. It'll be interesting to see what the full charge curve is like for the Air.
