It MIGHT be safe to do it as a one time thing when charging for an extra long trip, as long as the trip started as soon as the charge ended. As a default, no way.

Yeah and I actually did that for my Yakima trip in the 40. It was 168 miles over White Pass so I simply unplugged and plugged it back in after the charge completed. It would take as much as 10 mins before the charge rate dropped below 5 amps and when it did, I would unplug, wait 10 seconds and plug back in and it would start the battery evaluation process all over again but even after doing that 4 times, I didn't gain a single GID ?

As I said earlier, the 62 kWh battery already charges to 4.19 volts per cell if you let the charge cycle complete. I suspect the 40 kWh battery has a similar charge profile.

Yeah, agreed not worth it.

GerryAZ, with the 118F recorded in Arizona this past week, did your Plus hold up ok?


Separately, I was watching the Out of Spec Motoring North Dakota and Montana road trip in their LR Model 3. Some times they cut it very close, which I am not sure I would do with that sparse infrastructure that far north. In watching the off road sections, I quickly looked up that the M3 has just under 5.5" of ground clearance vs. the 7 1/2" (S+) or 8" (SV+/SL+). How much extra efficiency do you think that those 2 inches give the M3?

The month of July 2020 was the hottest month on record in Phoenix. The average temperature was 99.0 degrees F. There have been more days with official (Sky Harbor International Airport) low temperatures of 90 F or higher already this year than any previous year. I have a photo of the dash that shows ambient temperature of 118 F at 1759 MST on Thursday with the battery temperature bar graph 1 notch below the first red dot. The A/C performs fine under those conditions and I really appreciate the light colored leather interior which absorbs much less heat than the black leather in the 2015.

The latest 90-day adjustment on my car happened 7/19 through 7/20 and it resulted in significant AHr and SOH reduction. The gradual decline has continued since then with numbers right now: AHr=167.84, SOH=95.15%, Hx=105.33, Odo=19,322, QC=7, L1/L2=135. I plan to do my next full discharge test next weekend so I will have another data point showing actual energy storage capability after that.

By the way, I noticed there is a series of numbers in the lower right corner of the Monroney label (window sticker) that appears to have the manufacture date. My number starts off with 2019071900..... and the latest LEAF Spy number adjustment happened on 7/19 through 7/20 so I believe 7/19/2019 was when the computers were activated.

Even with your big drop, you still have more time and more miles than me and better numbers. I am thinking my reliance on DC charging is the likely culprit.

I don't know what to believe at this point--need more time and distance to know for sure. I doubt that QC is an issue in your cool climate. My LEAF Spy numbers really did not start to drop until I started telecommuting in March (reduced both daily mileage and highway driving). Since I doubt that I will be returning to the office on a routine basis any time soon, I may not find out if more daily miles and more highway driving improves LEAF Spy numbers (or at least reduces rate of decline).

Edited to add:
Efficiency for July: 1244 miles driven on odometer X 1.037 odometer error=1290 actual miles driven; charging energy from wall was 495.71 kWh so wall to wheels efficiency was 1290/495.71=2.6 mi/kWh. Efficiency is low due to numerous short trips with lots of A/C use so a significant amount of energy was used to cool the interior at the start of each trip (small price to pay for comfort).

SV+
705 miles
4.5 Efficiency. Lots of AC

About 500 miles in the S+
Not sure about efficiency as no Nissan Connect.
Local usually 5.7 m/kWh
Highway very dependent on speed.

Our S+ has been exactly the same for June July and August- 4.5 m/KWH, hilly dirt roads and very little AC, miles approximately 1000/ month. Winter is way worse because we use heat a LOT and AC almost never.....
