I've been logging the CAN traffic on my 2015 Leaf for a while and looking for rare events, I noticed some interesting transactions which only ever occur on the CAR bus just as charging begins. It looks like there are a couple of active queries initiated by the car itself from 71e and 71d with responses on 72e and 72d respectively. I haven't seen any discussion on these before (and they aren't on TickTock's magnificent spreadsheet). Has anyone else captured these or had a go at decoding the data?
Here is a typical sequence from the log; I've indented the data columns to help show the request/response pattern better:
