At 312 miles, it may be a little long even for the 85kWh pack (though average speed will probably be about 50 mph, so there's some hope.) Fortunately, the New Hampshire utility has EV charging at its Manchester NH location, where I can add a few "insurance" miles on my way home.
As a Roadster owner, let me insert some realism here. The Roadster is specced at 245 miles. That's the Ideal Range if you do a Range Charge on a new battery. The practical Actual Range is more like 180 miles - meaning accounting for speeds below 25 or above 50, plus stops/slow downs/hills. That's 74% of the claimed. I'll grant that 200 miles is do-able if you can keep your speeds down, but that's hard to do on the freeway, and there are other power drains if you're not on the freeway.
If you do a Standard Charge, the Ideal Range is typically under 190. I don't know off-hand what a practical Actual Range is because I haven't kept track, but I'd guess 145 miles is the comfortable upper end.
My calcs say the 85kWh battery will have a Standard Charge Ideal Range of 230 miles. The Standard Charge Actual Range will be more like 175 miles.
So, unless you're willing to make your first real drive start with a Range Charge, I'd suggest keeping your round trip to under 175 miles. And that's if you've got the big battery. And that's if you can resist testing out the 0-60 performance after every stop. If you're willing to do a Range Charge, then you might be able to do 230 miles.
As for charging en-route, what's the amperage there? A typical (eg, Leaf J1772) 32amp charging station will only put about 25 miles into your batteries every hour.
