So you have been actually taking temperature measurements while L2 charging?
Sorry, no but it's easy to see for yourself. L2 charge for an hour or more even in a cool environment in the shade (e.g. concrete parking structure) or at night. While charging or shortly after it's stopped, open the hood and notice the whole PDM stack is warm (not quite hot) and warmer than body temperature and ambient temp.
You'll also notice warmth around the inlet area.

Are you inferring that's a factor for Nissan's not using part of the cooling system to also cool the battery?
Yes. Circulating coolant heated by the on-board charger would almost certainly heat the battery pack in many/most cases.
Except during hot summer days, it's rare for my '13 battery pack to hit 90 F or higher, esp. given my car has no CHAdeMO. L2 charging from say 30-ish% to 80% on my '13 Leaf doesn't heat the battery much, only a few degrees F.
