What I would like to have is a table like this:
If the car does this =Estimate of consequences
---------------------------------------- ---------------------------------------------------------------------------
Temp > 50C (122F) for 24 hours =Void Warranty, probable x.xx% permanent capacity loss per event
(other temperatures and times) =(expected consequences)
...
Very low SOC to car stop =Probable x.xx % permanent capacity loss per event
(Other SOC states) =(expected consequences)
(At this temperature, using normal charge, output power cycle = blah blah blah, and other conditions)
Cycle 70% to 30% =xxxx total full battery cycles
Cycle 100% to 30% =xxxx total full battery cycles
(Other power cycles) =(expected consequences)
Cycle 100% to turtle =xxx total full battery cycles
(at cycle blah% to blah%, other conditions
Quick Charge (once a week) =xxxx total full battery cycles
Other important variables =(expected consequences)
Definitions, like "A full battery cycle is total initial capacity. Going from 60% to 50% ten times is a full battery cycle. 30% capacity loss is the service life end condition."
Without doing extensive testing with cells used in the Leaf, it is hard to see how this table can be made accurate. Only Nissan currently would have access to this kind of information. Releasing this can help the drivers of the Leaf get longer battery lifetimes, and to understand the battery life they actually get.
