None, but the Taycan will be able to charge at 270kW out of the gate, and as batteries get bigger/able to accept higher C rates there'll be cars that can use it. Porsche is talking about 400-500kW down the road, which won't be possible for 800 volt packs as long as the stations are limited to 350A, i.e. no more than 280kW, but if the input/output is the max. of 350A @ 950V, the AC/DC placard limits on the BTC chargers I looked at in Castro Valley, they could output up to 332.5kW (assuming a PF of 1.0).

. . . On 4 September, the day of the global launch event, a Porsche Taycan, with its 800-volt architecture, charged at Electrify America’s Bloomsburg, PA charging station. The vehicle charged at a maximum power level of 270 kilowatts, the fastest charging speed for passenger vehicles on the road today.
The vehicle, which drove approximately 250 miles directly from Niagara Falls, utilized Electrify America’s 350 kW chargers to obtain a 5 percent to 80 percent charge in just 22.5 minutes. . . .
