The first V3 Superchargers are being rolled out across North America now and will be built separately from V2 Superchargers. (Asia and Europe will start getting theirs by the end of the year). A brand new V3 Supercharger station recently opened in Las Vegas with 24 V3 chargers. Although any Tesla can plug into a V3 Supercharger, only Long Range and Performance Model 3s running the latest firmware will be able to charge at 250 kW. Standard Model 3s will continue to charge at 150 kW, while the Model S and Model X have received a firmware update allowing 200-kW charging at V3 Superchargers.
According to Tesla, the cost of charging will not change for V3 Superchargers compared with V2 Superchargers, and if you have lifetime free charging on your vehicle, it will be honored. V3 Superchargers will not get special signage (but the skinnier cable will be a tip-off). The difference should also be indicated in the car's navigation system when you select a Supercharger as your destination.
