Using a Tesla Supercharger: If the Model Y is charged using a Tesla Supercharger, the maximum charging power can reach 250 kilowatts, depending on the vehicle's battery pack configuration and the type of charger.
Using a Tesla Wall Charger: If the Model Y is charged using a Tesla wall charger (also known as a \"high power wall charger\"), the maximum charging power can reach 48 amps, which is equivalent to 11 kilowatts of power.
It's 11KW.
Then you have to apply for a meter, the 11KW charging pile needs to apply for a 380V meter, and the charging pile can be installed after the meter application is completed. Although the maximum AC charging power supported by Y is 11KW, I still recommend that you install 21KW charging piles.
