If the car sat on the dealer lot for a year fully charged, that wouldn't be good for it.
Yeah, I think even the dealers are a "bit" past that issue.

@ 15k, your stats are better than mine (107.42/93.05/120.21 @ 15,019.3 miles)

BUT...

@ 14,900.1 I am close; 109.21/94.39/120.13 8-)

FYI; your full charge stats are somewhat "shocking" I would tell you mine but mine hasn't been north of 85% in a while...

AND....

Since then, my degradation has slowed "a bit" Now at 24,900 and ahr 106.50 so less than 1% over last 10 K miles.

My own intuitive feeling is the rate of degradation is slowing but only time will tell. I can tell by your blog writings that you venture away from home more and DCFC much more that I do. The vast majority of my mileage is mostly commuting which takes @ 55-60% of the battery capacity depending on route, traffic, weather, etc... so easily keep it between 80% and 20%. Mine is charged almost exclusively at home, overnight after resting several hours following the commute, and rarely gets past 85-90%. So in other words, the 40kWh battery is likely sized just about right for my needs.

Also noticed that the L2 taper point is @ 90%, not 80% like my old 24kWh leaf so it's more difficult to time unplugging at 80% and almost always overshoot and get 85-90%. Mine was in shop yesterday for a tire rotation and they did 2 recalls (battery ground and something with the rear camera). I did not ask for the rapidgate fix because I rarely DCFC and don't intend to road trip with this car.

Road tripping is something I have wondered about as I didn't do any this year (under 400 miles doesn't count) and my daily commute is 25 miles so I pretty much live between 20 and 70% most of the time. My pack does get hotter because I rarely leave home over 70% and the last few times out that I QC'd more than twice, I left home under 50%.

Now last year, I think I only barely touched 10 temperature bars because the charge was so throttled but this year, I have hit 11 a half dozen times so not sure why my degradation has stopped. Now we are into Winter where most people's degradation slows way down. Mine never has but I contribute that to mostly mild Winters I experience but at the same time, my degradation has not been extreme excepting the first 15 months on my 2018

Wow. 11 bars. And I got freaked when mine hit 8 after a couple of DCFC’s. It rarely goes above 6. Think I’ll stop worrying. Lol.

I won't go so far as to say heat is nothing to worry about but you do more damage charging your car to full. But its all about the car filling the role you paid the big bucks for. Charge management seems to be a big hassle for an alarming number of people and Nissan helps with offering zero options. But its not that tough. If you are taking a long trip, sure charge it up but leave when the charging is done. It ain't rocket science. Your pack suffered but its like ripping the bandaid off. It was painful but it was brief.

But in the grand scheme of things; my 40 kwh pack is the least predictable of the 4 I've had so I have really no clue what will be true 6 months from now so as always; we shall see.

I hear ya Dave. We use the charge timer every day to charge between 1 and 3 in the morning. 240 volt 15 amp clipper creek. Puts in 6 kw every day. Covers my daily driving needs. Usually about 50 percent when I get home and around 70 percent when I leave. Once a month we do a road trip of about 220 km. We charge to full overnight and leave in the morning. A fast charge in the afternoon and back home. The car is freakin bullet proof. No idea on battery health as I don’t have plug share. We have all 12 bars though. 2016 SV 30Kwh.

Re: The 40KWH Battery Topic

Had to drive in for my 6 month service and the battery plate recall. My dealer is 90 miles from my home.

Left at 100% and arrived at exactly 15%. So 85% to drive 90 highway miles at 70 mph with a bit of terrain. Not sure if this shows I have lost real range as I do not do the drive often. But I remember driving it home having a lot more left.

Fast charged back to 83% in about 28 minutes. That fast charge jumped my batt temps from about 70f to 116f for the highest sensor. After my service I'll need to charge a bit more. Of course the nissan dealer let their fast charger break and wont fix it so a Honda dealer near by is picking up the slack. Thank you Honda!

DC fast charging did not appear to change my HX or SOH. Will post full batt stats next week.

Added detail on the battery for the trip:
So in the car it said I went from 100% to 15% but my kWh used for the 90 miles was 26.54. That sure seems like they are holding more in reserve than I thought. I thought about 36 kWh was useable. But 26.54/36 would have been 74% used not 85% as I did.

As a side note I got 3.33 miles per kWh average for the 90 miles at 70mph
