Power with Control
You can charge before then, just not as fast. Perfect world, you are at 60 when you arrive because you preconditioned before you got there. Might be reasons you didn't. Got into your hotel late and wanted to get to bed. Out early the next morning and the Supercharger is right across the street. What they have done is allow the Supercharger to heat the battery so you get to that faster charging temp quicker.
Keep in mind, if you are one of the +85% who charge at home, this only applies when you travel.
