How fast your Tesla will charge depends on your Tesla model, battery capacity, the charger you are using, and the charging circuit’s size. The charging speed will be determined by the amperage of the circuit (80A charger will be faster than 60A charger). It is crucial to know that level 2 chargers will charge a Tesla about six times faster. However, the maximum rate to charge a Tesla is 7.2KW – 11.5KW. The battery capacities of Tesla range from 50KWh to 100KWh.   The fastest charging time takes place between 20% and 80% of a full charge. On a 220V system, it takes about one hour to charge a battery from 40% to 80%, and at least 2 hours to charge from 80% to 100%. A battery with 62KWh – 75KWh capacity will charge fully in 7-8 hours at 220V at 11.5KW maximum charger rate. Also, a battery of 50KWh capacity charging at 7.7KW maximum charge rate at 220V will charge fully in 8 hours. Meanwhile, you can check the rate or level at which your battery is charging on the touchscreen. But if you are charging at a Tesla Supercharging station, your Tesla will charge faster because the Tesla Supercharger charges up to 150 KW, based on its version.
