From what I've read about the '13 model year I don't think they'd ever go with the simple 80% option as for whatever reason the EPA wouldn't give the Leaf the full 100% range, instead I believe they split the difference between 80 and 100%. ...
I believe the reason for the EPA range restriction was that Nissan worded its owners' manual to suggest that 80% was the preferred charge setting ("long-life mode" they called it). The gist was that 100% charging should be reserved for special circumstances because of detriment to the battery. With statements like those, it's only natural for EPA to rate the car based on the "regular", non-detrimental charge level.
Had they used different wording, I suspect they would not have taken that range hit.
