I imagine Tesla weren't terribly keen to press the point when he left Norwich because a journalist having to stand around for several hours in the freezing cold whilst the Tesla Model S charged wouldn't look that much better in print than the same journalist running out of power and having to be towed.
It would have taken him, oooh, about 8 hours to do a full charge at Norwich. What actually seems more likely - Elon Musk's insinuations that the only reason he didn't charge up fully there was because he was deliberately trying to run the car flat, or the journalist not wanting to hang around for an entire day in a small town in freezing weather?
He did not have to sit around 8 hours for the full charge, just enough to have the estimated range match how far he needed to drive. Then if it did not make that range, he could truthfully say that the car missed fell short of its estimate. As it is, he left on a 61 mile trip with the car telling him he only had 32 miles left.
And then Elon Musk would have again blamed him for not charging up fully there. He's already insinuating that the only reason not to do a full charge was because he wanted to run out: "On the third leg, where he claimed the car ran out of energy, he stopped charging at 28%. Despite narrowly making each leg, he charged less and less each time. Why would anyone do that?"
(Also, looking closely at the graphs I think I underestimated the charge times. It'd be more like 10 hours, which would basically wind up adding another day to the trip - after which Elon would presumably have written a blog post complaining that he could have just charged enough to get to the Supercharger and done the journey much faster, and use that as evidence he was maliciously trying to discredit Tesla. It's lose-lose for the unlucky journalist.)
The charging stations take one hour to fully charge the 85 Kwh Model S that was test-driven. A 30-minute charge would give the vehicle enough juice for 150 miles of travel.
