I am the owner of a Model S 70D VIN. Can't wait to get the car attached to it in a few months. I am reading this forum, looking through the manual and trying to know as much as I can on day one. Just yesterday I learned something new. That Tesla recommends you not charge to 100% to increase the life of your battery. I also know that when using a SC there is a sweet spot for recharging your car. Using EV Trip Planner I see that if I drive from southern NH to NYC I have a choice of many different SC's. Using this plan I can see one advantage is I can leave home at 50%, drive the 60 miles and then top off very quickly with free electricity. Or is that risky? What if the Worcester SC is out of service, maybe I should have enough to get to New Haven and charge in Hartford or New Haven. Or does the Model S' navigation do that thinking for me. How do you handle a road trip? Thanks in advance.
