I have had my 2017 for about 3 weeks and 1k miles. So-far, I have only quick-charged it! I wait until stored energy is below 40%, then charge it to 80%. Sample of these short charges have been 11kw-hrs, 14, 6, 12, 10, 11 10, 11 kw-hrs etc. Basically, 10 minutes or so of DCQC, every other day. It's temperate where I live, so battery heat bars have been starting at 5 bars, ending charge cycle with 6; or starting at 6 bars and ending with 7... and that is during the hottest part of the year.
The manual just states to avoid DCQC to promote battery longevity. My thought was that increasing battery temp only from 5 to 6 bars, or from 6 to 7, will probably do nothing to degrade the battery. And the DCQC is free power using Nissan Good-to-Go charging program. And it lets me stop charging at 80% easily. It's also along my commute, and I clear my email while I wait, so it's not inconvenient.
But really, the total savings of using free charging for two years is only $800-$900 for me. So I'm wondering: would doing nothing but DCQC (in short charge cycles at 7 bars of heat or less) cause $800-$900 of degradation to the battery (about 15% the cost of a new battery)? For all I know, DCQC-induced degradation is cumulative and linear. Or maybe it follows a "hockey-stick" curve, causing little/no damage until you get to 9+ bars.
