This still doesn't make sense, at least to me. If charging to 100% per
end-user instrumentation is actually 80%, then why would one ever
refrain from charging to 100%? Yet, some people say one should charge
only to 80% per instrumentation.
If the only reason Nissan provided the 80% charge cut-off is to reduce
"customer error factor" (I forget what that means), then it seems rather
pointless.

Rush and All,
I agree that the information can be quite confusing. I tried my best to
make it clear that what the engineer told me.
It was that 0% on the instrumentation is about 20% in the pack, and
that
100% on the instrumentation is about 80% in the pack. Thjis was the
best
that they could do to remove the customer error factor in the charging
protocol.
If you charge it to 80% per the instrumentation, it will not hurt your
pack, but you will of course experience lower range because you are not
charging to the full potential.
Hope this helps to clear things up some,
-Tom

Thanks folks
So if the Leaf charges at the 100% setting to 4.12vpc and 80% to
4.05vpc
and battery university says max life of 2k cycles is at 4.00vpc then
I
should change my charge cut off at 80% for daily short trips of 15
miles
typical. Plus since balancing occurs all the time there's no need to
charge at 100% except for long trips
Best regards
