Re: 2016 30 kWh Battery data

Sun Jul 02, 2017 12:38 pm

July is here and my battery stats have only dropped slightly through June despite a heat wave that brought 100+ degree temps for a week or more. I'm at 297 GIDs. AH=64.91 SOH=81%, Hx=74.74% milage is now 29779 with 46 QC's and 553 L1/L2 charges. Gauge is switching between 11 and 12 bars (11 after charging and then 12 after 20-30 minutes of driving). I don't know if the battery is finally stabilizing or if I'm just waiting for the other shoe to drop. At this point I've got a strong 24 KWH car which is adequate for my needs. If I lose another 3-4 KWH then I'm just marginal for daily use and will need to hit the QC station pretty regularly.

Finally lost the first bar for good. Just shy of 30,000 miles. SOH=80% 64.29AH. I now have a 24KWH car with about 75 miles total range. If my guess is right, the next 3 bars will be 10% each. That would mean that I will be down to 50% of original capacity before the warranty kicks in. I average around 15 KWH use per day. 10KWH of that is just to climb back up the hills going home. There's no way I'm going to try going home without at least 12-13 KWH in the battery. That means a recharge down the hill every day. I don't think that's acceptable.

Has anyone reported loss of a second bar on a 30KWH car?

Yes a member has already lost 2 bars at 31,000 miles

Stats on my 16 SL

Manufacture date 09/16
Odo 6655 km
AHr 80.74
SOH 100%
Hx 97.71%
16mv cell delta, (lowest I've seen 8mv @91% soc)
2 QC's & 221 L2's
Cell pair 28 has always remained blue ( since purchase) and will not charge to more than 4.102 v
28.1 kWh max usable capacity

The above stats vary slightly depending on ambient temp ,driving conditions and usage
I tend to drive the car in b mode utilizing as much regen as possible, try to keep the battery temps above 70F ( if possible) as the stats much improve especially over 80F and best results at 95F.
I leave the car overnight at 91% SOC at that percentage the cell delta is at it's minimum.
I try not to use cruise control as it keeps the battery too cool,I climb hills aggressively .
It seems the more you work the battery ( high as possible cell delta when driving and low as possible parking overnight) the better the stats remain.

I ran this today on my 2016 SV. We have two of them; I'll get the info from the other one soon. They were mfg about 6 months apart.

Wanted to give an update after 2k more miles.

Another data point after even more miles
Odo: 5843
AHr:74.98
Hx 89.84
SOH 94%

As a note, it's been fairly warm over the past couple months, and I've switched to all L2 charging.

Another month gone by and I've lost a few more GID's. Readings are 289 GID's, 63.32AH, SOH=79%, Hx=72.45%, 31505 miles, 50 QC, and 587 L1/L2. At this rate, I'll be looking at a new battery next spring somewhere around 43000 miles and 26 months ownership. At that point the range will be barely adequate for my daily commute and then only if I don't have any stops to make. I expect to make at least 2-3 QC every week by that point assuming I can find an open QC spot. Chevy's and BMW's are starting to show up pretty regularly at the EVGO station I usually use.

Ugh. That is tough. Are you still at 11 bars?

Yeah, still at 11 bars. The first bar didn't start to drop until I hit 82% and wasn't completely gone until I hit 80%. I've seen a couple of reports of the second bar dropping at around 77%. I wouldn't be surprised to hit 72-73% before the second bar goes.

Looks like they haven't managed to overcome the need for thermal management through battery chemistry alone. Given that the 30kWh batteries have a longer capacity warranty, you might end up getting replacement batteries TWICE before the end of your warranty.
Pulled the trigger on going EV on 10/2016 with a 2012 Leaf, and a Tesla Model 3 reservation expected to receive in June 2018.

Getting a couple of replacement batteries out of Nissan isn't the same as having a battery that actually lasts 100,000 miles. Nissan's promise was a battery that would still have 80% of it's original capacity at 100,000 miles. That might be possible in the northwest and Canada but it isn't going to happen in the south or southwest. Most of those cars will be lucky to last 60,000 miles. After 4 or 5 years most of them will need new batteries no matter how few miles they have on them. I'm seeing reports of low milage 30KWH cars in Texas and Florida dropping their first bars already. I thought that they must have solved the battery issue since they were offering the longer warranty and the Lizard battery was a substantial improvement. My mistake.
