I live 3 minutes away from a local supercharger. My Tesla S 70D is coming in about a month. Single charger. I drive only about 200 miles per week on average. Do I really need a home charger? Can I use the Supercharger and just "fill up" (don't shoot me for using a gas term) to 80% like I would get on a home charge. I would not get the 100% Supercharger charge unless taking a trip. My home is currently receiving 100amp service and would need to be upgraded to 200amp + a new breaker panel, breakers and the EV charger.
