Nissan refers to it as a "mandatory battery usage report". What you get is the nearly meaningless report that Nubo generously posted. But what the dealer's Consult II+ computer downloads from the car (and sends to Nissan) is a fairly detailed summary of usage for the past year. How many quick charges, max battery temps, number of turtle events, max time left fully charged or discharged... things that affect battery life. In other words, the car "rats you out" and tells of any misbehavior on your (or a previous owner's) part.
I've seen one report here where Nissan was refusing to replace a degraded battery due to something that was found in the battery usage report. I don't know how that turned out. Getting perfect 5 stars in all categories is not difficult, but a perfect score is not required by the warranty. The score sheet is more of an educational tool.
