2015: Battery Data Report @ 100% Charge

Most recent numbers on my 2015 S. 20,225 mi, mfg 4/14. Taken yesterday 11/14/15

271 GIDS
21.00 KWH
97.15 SOC
87.22 SOH
88.58 HX
57.59 Ahr
61 Degrees Temp

I also want to point out that below is a reading from 12/2/14 (last year) with about 4,000 miles on the car.

276 Gids
21.39 KWH
97.31 SOC
88.76 SOH
90.57 HX
58.77 Ahr
61.3 degrees temp

But here's a reading from 7/13/15 with 13,300mi on the car.

288 GIDS
22.32 KWH
97.25 SOC
92.54 SOH
94.70 HX
61.31 Ahr
81.6 degrees temp

My point is that my car last winter, with only 4K miles, was tracking fairly low as well compared to 292 just a couple months before, but during the whole Spring/Summer (March-September) it was between 283-288 Gids. So I am confident that we are looking at a moving target here and even though I'm getting 271 now, I was getting 276 last year with very similar temps (its been cold in CA these past few weeks). My estimation is that when March/April comes around, the car will be averaging about 5-8 Gids less than it was last Mar/April, so I can anticipate about 278-283 for next Spring/Summer.

But yes. To share others sentiments. I think the Lizard battery isn't much more than a 13/14 model year back with improved chemistry to avoid warranty swaps in Arizona/Texas, and perhaps an extra kWh of capacity built in to eat up some of the early degradation.

Here's my New leaf battery stats back around the end of January 2015.



And today 15,000 miles later .

Since my wife has been driving the car and it hasn't had any L1 charges I noticed that the battery voltages at max charge were more varied so this past weekend I left it 120v charge 2 nights. It smoothed it out a lot and the stats went up from 98% SOH by 1% and 1 GID after that too but only .01Ahr

My #'s continue to increase over last 350 miles. Still waiting to get my L2 installed so hope upcoming L2 charging with BMS learning will increase #'s further.

As I've said before. Mine dropped as low as 270 around this time last year during its first winter and around the same mileage, but then picked back up in the Spring and was tracking at 288 or so. Hopefully yours comes back up as well, but yours are oddly low for a 2015 pack.

It's been a while since I posted, but my results are tracking similar to tkdbrusco's, in that they were similar to what I got back in January (at around the same battery temps), went up a bit in the summer to peak at 291 GIDs, and are now back where I started. It will be interesting to see what happens over the winter and into spring.

Is anybody compiling all this data?

I think one thing that we can say for sure is that the only people on this post that consistently have very high GIDS live is very cold areas of the country (or world). For those of us in warmer areas, we area seeing a rolling degradation, Gids drop in cold, come back up in summer, drop more in cold, come back up in summer, etc... This gonna make the first bar drop interesting because what happens if it drops in the winter but then Gids pick back up in the summer? Either way, I think I'm good through next winter. At this rate I'll be high 250's in winter of next year, maybe get through the winter without a bar drop and squeeze 40K+ miles out of the first bar.

As far as data? I have been taking screenshots of all my readings with mileage, so I suppose I could build a pretty decent graph. I've just been too lazy to do so.

I had 55.64 AHr yesterday. I looked up on the wiki and saw that people have lost their 1st bar around there, some even higher.

Can't believe I might lose a bar already. (only 7 months and 4,400 miles) Keeping an eye out for it. From what I've gathered, AHr is what people are looking at mostly for bar losses.

The one stat I'm still really confused about is SOH. The 1 bar losers have SOH from 83% to 92% (with corresponding AHr of 53-55) yet I still have 99%. Maybe I won't lose a bar because of the high SOH?

My last report at 100% 20,600mi

268 GIDs
20.77 Kwh
97.23 SOC
86.27 SOH
87.27 HX
57.16 Ahr
63.6 Degrees

This was my first 100% reading under 270 Gids. Not too happy about this, but what can I do. My SOH is much lower than yours, but I do have a lot of miles on the car as well as two summers of driving and my second winter. Here's my estimation on bar loss. Mots people are saying that they lost them between 53-55 Ahr, but those were all on non-lizard packs, so who knows if the numbers will remain the same on our cars. If you go by percentage of capacity loss, other cars were at losing their first bar at 15% loss. For our packs with max Gids of 292, this would be at 248 GIDs. Also if you look through the posts on this thread, one thing I've noticed is that cars from warmer climates have greater fluctuation from summer to winter, which I find really weird. Last winter I was down to 271 at my lowest reading (this was with about 8,000mi) and then It went back up to as high as 288 during the summer (with about 14,000mi), now I have my record low of 268? So my hope is that come the spring/summer, I'll be back up into the 280's again. My guess will be that next winter, I'll be down into the 250's and 54 Ahr and I'll probably wind up losing a bar next year around this time (with about 37,000mi). My guess will be that you will be in a similar boat. However, losing a bar anywhere below 40K on the lizard pack would be a failure in my book. I think that the battery should be able to get to 50K with about 10% loss. I get that smaller batteries cycle more frequently than larger ones, so the 5% loss over 100K miles that the Tesla gets is not realistic for any low range EV, but they've got to do better. I was hoping that I would be able to sell the car in mid/late 2017 (when the Model 3 is finally available) with all 12 capacity bars, but I think at this point, there's no chance of that. By then I'll have nearly 50K miles on the car and I hope I'll have at least 11 bars. My break even goal was to sell the car at $13,000, but I think $11,000 will be a bit more realistic. Oh well

And a record low this morning....

266 GIDS
20.61 kwh
97.2 SOC
85.55 SOH
86.29 HX
56.68 AHR
60 Degrees Temp

Granted it was below freezing in CA today 34 degrees outside, but these are still about 9% down from my max of 292 when I got the car. Considering that the car was at a low of 273 last winter, and it will likely drop a few more Gids this winter, as we are only in November, my guess is that I am looking at 5% average annual degradation, at my use of 16,500/mi each year. This estimate puts the car at about 20% loss at 60K miles. Not anything spectacular by my estimation.

I should have just bought a Volt. There's a part of me that wants to sell this and go buy a 2016 SV with 30kwh, but the math just doesn't make sense. Even though I can buy one with rebates right now fro $21K out the door, there's no way that it makes financial sense in the end. My best play is still to drive my 2015 until I can get my hands on a Model 3.

Huh, guess the lizard pack has issues too. How are your cells?

My readings just went up again. No clue why.

Your pack looks fine to me.

You got 22.5 Kwh in a cold pack.

I got about 21 Kwh on a full charge but my Ah reports 65.7 now at exactly the same mileage as you in a 2015 Leaf. My health is 100%. I have about 160 or so QC and 700 and something L2.

it's about 53.6 degrees F here.

Check out my leafspy screen shots a few pages back.

I think so, at least in certain circumstances. Do you mean the blue/red lines? Usually, they're mostly red from L2 and mostly blue when QC.

Nice #'s! I had a thought, maybe mine were down because of the cold but my recent temps are 50%+ higher than yours so that can't be it.

I honestly have no idea what the heck is going on with these 2015 packs. They are all over the board. We have people that have high SOH but low Gids and Ahr, meanwhile my max Gids are at 266 now with corresponding SOH and AHR. We have people in Ireland who have had great reading for 30K plus miles? Who the heck knows. The only thing that I see out of this that seems out of the ordinary is that we are experiencing max Gid/Hx/Ahr fluctuations from season to season. The fact that mine was at 273 last February and then all of the numbers rose into the summer and it got to 288 at one point before now coming back down to as low as 266? I don't have a clue what to make of this other than the fact that my numbers might go back up in the summer... hopefully?....

On a more somber note, I called about a 2016 SV to see if I could get a good deal on one and the sales manager quoted me 24K out the door for a 2015 S QC! That's $14K after rebates! And I thought I got a good deal on my 2015!? If I needed another leaf, I'd buy one right now.

Don't feel bad, mine has about the same numbers with only 4 QC's. Really strange the sharp drop in the last month.

Yeah, the screen with the red/blue lines. Are they all about the same value? If one cell pair is very different, that's worth checking out.
