I think I had 200 miles or so range (MYLR) when I picked up, wound up stopping at a Supercharger on the way home because it was down to about 20% charge when I got home. First Supercharger stop is a trip because you just plug in and it goes and they chase after your billing info later.
If you do use a SC on the way home, make sure to either set it as a destination or it's on your route on the map. That way it will pre-condition the battery before you stop which saves time.
Again, for the uninitiated: If you plug your destination into Nav and it has you stopping at a Supercharger, it'll put up the, "Preconditioning the Battery" message when it gets close to the SC it has you stopping at. Admittedly, sometimes the car's idea of "close" can be, "90 miles away", but, why argue with the car?
Another example: Say that your destination doesn't have Superchargers near by, and/or the only charging solution is a 120 VAC line to the house, or anything like that, and maybe You've Got Plans to show off your Shiny New Car to every friend and relative in the tri-county area
. So, you're going to need ~150 miles of charge on the car when you finally get home, but the Nav, being the Nav, has you getting home with 10% SoC. (This will show up on the Directions part of the Nav, after you put your destination in, and it's just figured out how to get you where you're going.) Which would be fine if you'd be charging overnight, but you're not.
So, in the bottom right side of the Nav screen, tap it. A set of three icons will appear, one of which will be a lightning bolt. Tap on the lightning bolt; every Supercharger for a good-sized area around will appear, usually with the Nav screen zooming out to encompass them all. You can pan and zoom; find an SC close to home, and tap it; it'll do a routing to
that Supercharger, rather than your house. And then you can do a final charge-up so you don't have to spend a half-hour charging somewhere with kvetching relatives in the back seat. And the car will start doing its pre-heating thing on the way to that Supercharger, thus minimizing your time spent charging.
