The SOH and Hx figures move around some.BuckMkII wrote:The SOH went down a point between the day of the test drive and the day I bought it (last Wednesday). It has stayed at 85% since then.
Based on my test drive data, I had calculated the battery capacity as 20.4 kWh, which seemed consistent with an 86% SOH:

This morning SOH had ticked down to 84%, but after driving to work, it's back up to 85% and Hx is up a couple of tenths to 82.58.cwerdna wrote: The SOH and Hx figures move around some.
I wanted to do that today but we "had to" charge at home (for the first time) last night (L1 from 37% to 80%). Battery temp was a bit higher than I would like (mid-70s IIRC; yesterday was "hot" by Seattle standards and I was too dumb to game the charging timer to delay the start of charging until after midnight and just have it run for a few hours as a range cushion, which I thought of only after I'd driven 3/4 of the way to work...I need to figure out how to do that).They may improve if you get the battery down to fairly low % SoC (say below 25% on the dash display) and charge back up to 100%, letting it stop by itself.
Yes, I've been to Livermore once when it was hot AF. I lived in SF for almost three years and took a windsurfing class at Lake Del Valle once. The car seems to have often been charged twice a day (2400 charges in < 4 years, average 16 miles per charge) so bopping back and forth from the East Bay to Livermore and compulsively charging at both ends is a likely scenario.I wouldn't bother with any kWh calculations. Leaf Spy seems to default to 1 gid = 77.5 Wh. See my comments at http://mynissanleaf.com/viewtopic.php?p=481367#p481367 and http://www.mynissanleaf.com/viewtopic.p ... 92#p476092.
If you bought the Fremont, CA car, that isn't a cooler part of the Bay Area, but also isn't really crazy hot either. Unfortunately, the car may have sat in the sun in hot parts of Bay Area. Examples: http://www.mynissanleaf.com/viewtopic.p ... 60#p464260.
I wouldn't put too much stake in the L1/L2 count. It has some quirks that could make it MUCH higher than the actual charge count. See http://www.mynissanleaf.com/viewtopic.p ... 26#p452126. Mine's at 2966. It looks like it was around 1640 at the time I looked at it/bought it on July 16, 2015, for a delta of 1326.BuckMkII wrote: Yes, I've been to Livermore once when it was hot AF.

The best time to check it is probably right after a 100% charge. After an 80% charge is likely NOT the best time. The charge lights behave as if there is equalization after an 80% charge, but that may not be what actually happens.BuckMkII wrote:OK, this morning did the L2 charge at work until it shut itself off (battery temp finished at an average just under 73°). My driving plans through Friday evening should make a good dent in this charge (8 miles today, 23 miles tomorrow, 33 miles on Friday). If that doesn't at least get me down to LBW, either I'll drive laps around the neighborhood Friday night with aggressive hill-climbing, or run it low on Saturday with errands, then do an L1 at home to 80% and see what the software thinks after that.
Unfortunately, after a nice day today, we're going to have good battery-charging weather (highs in the low to mid 60s and waves of rain) throughout the remainder of the one-week forecast!
Jeez, another quirk?!? Okaaaay.cwerdna wrote: I wouldn't put too much stake in the L1/L2 count. It has some quirks that could make it MUCH higher than the actual charge count. See http://www.mynissanleaf.com/viewtopic.p ... 26#p452126.
Why a midnight-to-midnight timer? I've given only the briefest glance at the timer issue. I'd have guessed that would make it wait until x hours before midnight to start charging (where x is the calculated time to charge), but unless you work nights that must be wrong!On weekdays, it's usually just charged once at work (almost always with a midnight to midnight 80% timer Mon thru Thurs) and that's it. On some days, I remotely trigger it to go to 100% about 1-2 hours before I leave. On virtually all weekdays, I don't
