a QC user goes x miles has x degredation.
a non qc user (him) goes x miles has similar x degredation.
qc does not adversely effect the battery.
the logic is sound. if it matches results. I tend to agree with him from personal non electric car battery experience. (my 12 leaf has no qc port)
fast charging does not necessarily damage a battery. HEAT damages a battery.
if you QC a lot but don't overheat the battery your probably not going to see dramatic losses from the QC process
BUT if you QC and this results in a frequent hot battery you will see losses but its not the qc doing this its the HOT battery doing this.
of course if your qc causes the hot battery.....
at least THAT is how I understand it.
You mean like this?
I've found the temperature increase from DCFC to be about the same as L2 charging for the same amount of energy input.
The issue with DCFC is that it enables more miles to be driven and for multiple DCFC charges in one day. Serial use of DCFC in one day will elevate temperatures well above what you could accomplish with L2 only. So DCFC *could* impact the battery more but typically it doesn't.
I don't believe DCFC has a significant impact on battery degradation if performed just once in a day per Nissan guidance.
