I get some very inconsistent measurements from LEAFSpy on my '15 S. I've seen the SOH actually increase at times! Don't stress.

Yeah, the Ah bounces up occasionally, perhaps by around 0.5 or so. But he's already about 8 Ah off what a new pack should be and falling with a "brand new" car! This is not normal.

Thanks Valdemar,
Seems wrong that a new vehicle would already have 7% degradation. I will update with any changes in readings over time.

Should I contact Nissan to tell them that my new vehicle has this issue?

probably good to start a paper trail of your issues. I also think your numbers will rebound. You realistically should not see any degradation for 12-18 months from new. the time between manufacture and purchase is a concern however. We had a long hot Summer but what is really needed is a bit more detail. how many miles on it on delivery?

All of the QC around here seem to be broken.

An electrician working on one of the EVgo units in San Jose told me to plug in the QC first then swipe the card to start, otherwise it makes a comm error and they must reset it before it works again.
Also if the metal head is dropped twice the whole cord has to be replaced at $4000.
Once I learn how to do it, I am going to post my LEAF Spy screens from yesterday. I went down to VLBW as requested by drees. I hope it helps you in some way. I, too have a car which sat a long time. FWIW, with the A/C on most of the day and making no effort to hypermile, I went 78.8 miles.

Agree on not focusing too much but I am watching the numbers.
Today at SOH: 90% and AHr: 56

After 100% charge I get 86 miles on the GOM. That seems lower as well.

Edit Summary:
09/29 - got new car
10/01 - SOH: 95% (first measurement)
10/03 - SOH: 94%
10/05 - SOH: 93%
10/07 - SOH: 91% AHr: 57
10/09 - SOH: 90% AHr: 56

I'm in a similar boat with the OP. I purchased my leaf on 9/30/15 and didn't know to look at the manufacture date or use LeafSpy at the time of purchase. I thought I was getting such a great deal with the purchase price that I kind of rushed it. I didn't realize the 5k NMAC cash would be renewed the next month.

After I got LeafSpy in late October I started tracking the numbers:

10/29 - SOH: 99% AHr: 61.7
11/2 - SOH: 97% AHr: 60.6
11/9 - SOH: 94% AHr: 58.7
11/16 - SOH: 93% AHr: 57.9
11/19 - SOH: 94% AHr: 58.5
11/22 - SOH: 95% AHr: 59.8
11/23 - SOH: 96% AHr: 60.2
11/24 - SOH: 98% AHr: 61.1
11/27 - SOH: 99% AHr: 61.5
12/01 - SOH: 95% AHr: 59.5

As you can see, it's quite the roller coaster. The 93% after only 2,000 miles really scared me, but then it climbed back up to 99%. I just checked the date of manufacture tonight and noticed it is 02/15. Needless to say, I'm disappointed in myself for not doing more research before jumping on the deal. Hopefully the battery will hold up for the way I intend to use it, but I'm worried this will degrade faster than expected.

Don't feel bad. Your not the only one. I learned about battery life and manufacture date too late. I bought our '15 SL on 11/2/15 which was end of month (Oct) for dealer book closing. I realized after purchase it was manufactured 7/14

I negotiated $5k dealer discount off MSRP plus $6k rebate applied as down payment plus our income qualifies for the full $7.5k tax credit. How the NMAC Cash $5k became $6k I don't know. I was negotiating "out the door price" so the dealer found a way to bump the NMAC cash to $6k for a total discount+rebate+tax credit of $5k+$6k+$7.5k=$18.5k

Here are my LeafSpy numbers after only 750 miles on the odometer and one month of ownership. I'm not worried. Worst case at 5 years of ownership the car will be actually 6+ years old and likely need a battery under warranty.


11/15 SOH 95 Ahr 59.04
11/18 SOH 94 Ahr 58.85
11/24 SOH 94 Ahr 58.67
12/02 SOH 94 Ahr 58.90

We really like the car. It's great for running around town. We rarely exceed 60 miles per day and have a 2015 Lexus RX450h Hybrid SUV if needed for longer trips.
 
Similar here... Bought beginning of September this year, later looked at the MFG date and it was September last year. Got LeafSpy after a month, so already had 800+ miles on it by first measure.

12/3 - SOH: 92% AHr: 57.42

@Flyct & @iminsandiego, what sort of charging do you do? I've been doing nearly entirely L1 charging (with a few QC thrown in for longer trips) and I wonder if that has something to do with it. The odd bump in there where the SOH was 97% happened after a road trip where the destination had free L2 charging, so I was able to top off using L2 charging. I didn't record the stats after that charge, but that 97% showed up the next day after my regular full L1 charge. After I went back to my normal charge routine it dropped back down. I was avoiding having an L2 EVSE installed because I didn't really need the range, and it will probably be a bit pricey to run a new circuit as I live in a condo, but I'm starting to reconsider.
 
@Tyger,

I installed an Eaton L2 EVSE at home on 11/16. Before that I used the Nissan L1.

My first LeafSpy Fully charged
GID was
272 on 11/15 w/odo 472 miles
277 on 11/18 w/odo 523 miles
271 on 11/24 w/odo 586 miles
268 on 11/27 w/odo 612 miles
272 on 12/02 w/odo 739 miles

I got LeafSpy on 11/15th.
 
That's unfortunate that yours was an entire year old. There should've been a good discount for that.

It appears that you have similar behavior to mine. I'm actually doing about 60% of my charges L1 at work and the other 40% L3. I don't usually do more than 10 minutes on the QC, so the battery never even has a chance to heat up. The battery temp has almost always been in green according to leaf spy. I don't think I would spend the money on L2 unless you need the faster charging at home. Although it is more efficient than L1, I don't think it's worth the expense.

You're right that efficiency wise it's not worth the cost. With the price I pay to charge overnight, it is basically $5 lost per thousand miles to charging overhead of L1 over L2. There are a few times I'd like to get more of a charge than I can squeeze into the low cost TOU rate time at L1 speeds, and that would save a bit more to have L2 then.

However if only using L1 is having a real impact on range, that could change the cost/benefit equation. I'll have to see if I can find some L2 to do a full 100% charge on sometime and see if I see the AHr and max gids go up again.

I am guessing you charging to full every day then? because I don't think that consistent charging that does not do any top balancing is numbers I would take too seriously. also keeping in mind you have to discount the daily variances. your range of numbers is much smaller than mine but mine have taken a weird upswing ever since a trip made 2 weeks ago...

Most times I charge it is to full; and I only record the battery stats after charging to full. It's not every day, but that's because many days I only go a handful of miles.
 
On Nov 18, I have just got a 2015 Leaf SL which made in May. My SOH continue to be at 90/91% range, but my GID at full charge is about 284.

I did not have L2 installed yet, and I only use L1 to charge at this time.

That's really interested. We'd expect a new car to have 281 gids and with a 90/91 SOH to have a 9/10% lower gid value. Would be interesting to do a batter capacity test to see if reality is actually 100% capacity or if it's 90%. One method is to drain the battery completely, then recharge while measuring how much power is going into the car.

I just did a full charge last night (the first in several weeks). I checked with leaf spy to see what the GIDS was and at first it showed 278 with 21.5 kWh remaining, which I was quite happy with considering the SOH says 95%. Then I disconnected and reconnected a minute later and it showed 272 with 21.1 kWh remaining. I have no explanation for the difference. At least my SOH hasn't changed in a week.


10/29 - SOH: 99% AHr: 61.7
11/2 - SOH: 97% AHr: 60.6

12/1 - SOH: 95% AHr: 59.5

I have one of the first 2015 models. Mine was manufactured in 4/14. I bought it in 8/14 and for the first few thousand miles of driving, it would read 292 Gids at full charge. I think this is the highest a 2015 will ever read. The 2011-14 models had max of 281 Gids at full charge. As my first winter approached in CA (last year), my readings dropped down to as low as 273 (but mostly higher, around 280 or so), then as the temps picked up in April/May, all of the numbers picked back up and I was getting reading usually between 285-289 (never saw 292 again). Now that it's winter, they are all dropping once again. When is was low 30's a few weeks ago I was as low as 266 on one occasion. My most recent reading a few days ago is displayed below. This is with 21,000 miles.

273 Gids
21.16 kwh
97.41% SOC
87.61% SOH
89.11% HX
58.04 Ahr
60.8 degrees

I have seen the max GIDS, SOH, Ahr, and HX swing wildly from season to season and I try not to concern myself too much with all of this. I think the SOH number is not a true representation of loss as it seems like the car holds about 5% of unused capacity in the battery. It seems like the actual loss is the difference between the SOH reading and 95%, or in my case, about 7.4%, which accurately corresponds to the 273/292 comparison to full GIDS. While this might represent a 7.5% drop in range as of today, I fully expect the GIDS (and other numbers) to rise again when the Spring weather comes around, although I doubt I'll be getting high 280's probably more like high 270's or low 280's. If you look at these rolling numbers they compute to about 3-4% loss over 12mo/15K miles, which is much better than the early 2011/12 cars. Some of those cars in warmer climates were losing bars after only a few thousand miles of driving, and I doubt a 2011 in the bay area would still be at 12 bars after 21K miles. At this rate I'm expecting to lose my first bar somewhere between 40-45K miles. I'm not thrilled about this, but its better than the old cars.

I am living in Canada, the temperature now is much lower than in California. Is that part of the reason that I have got lower SOH and GID number? BTW, I will try charge to 100% again tonight, and it is not too cold today and I have just got my L2 charger installed.
 
My car's SOH and capacity remaining at full charge has been creeping up the last couple weeks until I finally reached 100% SOH again. This occurred on a long trip up a mountain to a ski area called Big Bear. I trickle-charged overnight with my cord sitting in the snow and the next morning the car reported it's highest capacity since buying it.
