Re: Capacity Loss on 2011-2012 LEAFs

Sun Apr 16, 2017 1:45 pm

Hi

I am in Nevada…..well today the fourth bar went….now to 8 on my 2012 with 27k . My warranty expires in December, I am getting 60 miles on the clock after charging, but it quickly decreases to the 40’s after just a couple of miles of travel. Would you suggest to wait after the hot summer or have it done right away. I have adjusted to keeping my distances in check. Do you know if Nissan is replacing the packs with the 2017 models? And will waiting be beneficial to getting the newer packs? Do the newest packs have a name to ask for?
Thanks,
Larry

If you can wait, it will be beneficial, especially if you can avoid some time in summer heat with the replacement pack. There's a slim chance that Nissan will make 30 kWh packs available as replacements, considering that they aren't making 24 kWh packs any more (do they still offer the 24 kWh pack anywhere?).

But hasn't Nissan repeatedly said that it's not possible for them to replace a 24kWh pack with a 30, because they operate on differently-colored electricity (or some equally plausible reason)?

No, Nissan has simply said they don't ever plan on doing it, not how difficult it is. In reality, it should just take some ECU remapping to make it work. The bigger issue will probably be the QA testing required for them to be comfortable releasing it, which would have no immediate financial return (at least for the bean-counters).

It's too bad, as Nissan has really fallen short in doing a good job of taking care of early adopters having left so many with a product that is drastically underperforming their promises.

They've given some reason, last I heard was because of homologation.

Some posts I made about it:
viewtopic.php?f=4&t=17168&p=476800&hilit=homologation#p476800
viewtopic.php?f=4&t=17168&p=476802&hilit=homologation#p476802
viewtopic.php?f=4&t=17168&p=476817&hilit=homologation#p476817

Someone else stated here or on a FB group I'm on that another problem is the discharge curves are different between the 24 and 30 kWh packs.

I would definitely wait until there is about a week left for the warranty, especially in the heat of Nevada. Why get it replaced now if you can live with it? I kept going until I reached just a few miles under the 60K limit, and got through the summer here in Florida. I still had more time left, but no more miles. With more miles I'd be driving it as much as possible from now until the end of November.

I did get LBW warning yesterday (below 30 degrees) after about 38 miles of driving 40 mph.I was on the last bar with 3 mi on the GOM when I made it back home. I've seen it go up and down over time. Mostly down. But, this is definitely the largest increase I'e seen. I've charging to 100% all winter.


In Feb, my Ahr was 45.35. It has been increasing with the rise in temps. Current temps are 55-60 and is quite cool for this time of year. As of today, my Ahr is 47.09. Weird that it keeps going up. Car hasn't had a QC since last fall. But, I have been charging to 100%. Not sure if it would go back down if I charged to 80%. I am now thinking I will not drop the 4th bar before 11/15 when the warranty is up.

Dropped to 7 capacity bars over the weekend.

39.29 Ah, 38.36 Hx, 169 GIDs / 139 GIDs 100/80%

About 2 weeks shy of 6 years of ownership and 61.5k miles - this last bar took about 9.5 months and a bit more than 8k miles.

Range at an indicated 4.0 mi/kWh is in around 36-38 miles to LBW and 44-46 miles to VLBW.

At this rate, losing about 0.5 Ah/month or 6 Ah/year or 2 kWh/year, if I could make the car last 10 years, it will be down to 15 Ah or less than 23% capacity remaining. That simply will not happen. Another year and I'll be hitting LBW on my commute and that's without lunch or errand trips.

I'm staring at the Nissan LEAF Battery page and looking at the quote:

KATIE M., NISSAN LEAF OWNER - "GOT THE 15K MILE CHECKUP ON MY NISSAN LEAF — IT WAS JUST $20 FOR TIRE ROTATION, CAR WASH, BATTERY TESTING"

Hah - I never made it out of the dealer for an annual maintenance visit for less than $120 - and that's with declining things like cabin air filter changes, etc. I'm taking it in tomorrow for the recommended 60k checkup (battery test, brake fluid flush, cabin air filter) - quoted price? $300. And that doesn't take into account the $6000 bill I'd face for a new battery. I'm not even sure why I'm spending the money, honestly. I guess I'm still holding on to the faint hope that something catastrophic happens to the battery within the defect warranty so Nissan has no reason to reject the claim.

Took it on a bit of a road trip this weekend, mostly just to see how it would do as I haven't really done anything besides commute in it for a while, drove 46 miles to a QC arriving just above VLBW with the help of some traffic, but crosswinds didn't help. Charged 30 minutes to 80% (but only about 11-12 kWh) . Drove another 20 miles topping off on L2 at a hotel. Drove 20 miles back the next day to same QC, charged until the car stopped after 30 minutes, at 90%+ charge. Babied it the remaining 40 miles home, arriving not far above VLBW. At least on the way home traffic was light and I ate dinner while charging, so no real time lost there.

Probably won't do that again unless I'm looking for the adventure. It would have been faster to take the train (thanks to traffic and arriving at the first QC stop finding both QCs in use by i3 REXes and having to wait 15 minutes). Also surprisingly, not that much more expensive given the high cost of QC on the EVgo network without a subscription plan.

Tpsfoto,

My battery was replaced before the summer and the new chemistry battery seems to be holding up very well in the Phx summer. Dramatically different than the previous chemistry.
Waiting for after summer would be the best, but if it inconvenience your life, you may want to change it sooner.
A new battery makes the car feel like it is new again.
Since I only charge to 80%, I find my efficiency miles/kwh is also much improved 4.3 (and we drive fast down here)

@Drees,
Did you have another go at Nissan, now that they are at least considering monetary participation in cars outside of warranty ?
