Remember, I am an accountant. Perhaps my brain is wired differently from most normal folks. Right now, I think there are a number of you who own two Teslas. My wife and I have a deposit down on the Model III. I know a lot more of you have reservations on the III as well. A year or so from now there will be a lot more two-Tesla households. Many of these households will only have one 240-volt, 50-ampere plug available for charging at home, and will not or cannot add another to accommodate the second car. Reasons will vary--perhaps not enough space in the panel for another 50A plug--cost--remodeling of garage--space--there could be others. Overnight charging is always best. Why not split the UMC into two plugs so that both Teslas could be plugged in from the same receptacle simultaneously? I am sure there could be a way to adjust the current between the plugs in coordination with the automatic start time that we dial into the car on the touchscreen. Here is my thinking: Set Tesla A to start charging at midnight at 40A; set Tesla B to start charging at 4:00 AM. A receives the full amperage until 4:00 AM when the software will adjust the amperage based upon estimated time to finish charging. If A is completely charged by 4:00 AM, B receives the full 40A. If A needs another 10kWh and B needs 35kWh, then the software calculates the proper split between A and B. Once A is complete, then B gets the full rate. Of course there may be times when this is problematic, but then the owners would just have to start the charge time earlier. Our driving habits are such that I rarely need more than 25 kWh overnight. My wife probably would not use 25kWh in a week. This sort of set up would work nicely for us. But I do realize that our situation may not be a common one. Oh, did I mention that I am an accountant?
