Re: 2013 Leaf bar loss.

Thu Sep 15, 2016 1:25 am

I was just about to post the same thing. For an early '13 pack to keep all 12 bars in a hot climate for that long would be amazing enough, but for it to then drop three bars quickly? Fishy, unless the original owner kept it in an air-conditioned garage and the second parks it outside...

If that occurred, can the true SOH be found within LeafSpy? Or would the reset be tricking LeafSpy too?

It might not show up right away, but within a few weeks of using the car, it should regain its accuracy.

Yes.
I think SOH would be wrong for a fairly long time.
Multiple weeks. Maybe 4 to 8 weeks like it is following P3227 software update.

drees stated previously he thought Hx would drop fairly quickly:

Well, it usually doesn't take much driving to get the Hx value to drop if the BMC was reset. A few test drives should be enough to bring it down.


If P3227 was done shortly before you got the LEAF that can also cause bad readings. P3227 caused my SOH to jump from 64% up to 76%.

the reset will make SOH go up but AHr will be accurate after a full discharge / full charge cycle. Just drive to Very Low Battery Warning then charge to 100% and the next day you should know the AHr.

If the AHr and bars don't agree roughly with this table it was reset.

Loss of bar 12 - between 53.75 AHr and 56 AHr
Loss of bar 11 - between 49.75 AHr and 52 AHr
Loss of bar 10 - between 45.75 AHr and 48 AHr
Loss of bar 9 - between 41.75 AHr and 44 AHr

...

I do not believe that is correct.

Several years back TickTock's dealer cleared his long term capacity loss data twice.
He posted his curves.
They did not return to normal very quickly.

They were very slow to return to normal, just like my AHr was following P3227.

If anything returns to normal fairly quickly it is probably Hx as drees speculated, since that is a function of electrical conductivity.
The LEAF can probably measure and adjust that parameter fairly quickly.

The BMS calculation of AHr is likely much more involved.

Car is on Oahu, Hawaii.

The original owner took delivery on Oahu 5/2013. Manufactured 3/2013 .

I bought used 01/2015 as a lease return w/all 12 capacity bars @ 20,000 mi. Original owner turned in for 2015 leaf.

I have lost 3 bars within the last year. 3rd bar drop middle of August. Car now has 24,000 mi,

I just purchased Spy Leaf Pro, and my readings as of today;

AHr= 45.06

SOH- 68%

I charged to 100% and my SOC = 93.9 %

14.6 KWh

54.5 miles available @ 4.0 miles/kwh

188 GIDS

I enjoy driving the Leaf. Hopefully qualify for battery replacement by end of warranty term 5/2018. I will then continue driving the Leaf until

new battery falls below 70 %. No need for a larger capacity EV as this one suits us fine. May consider buying a 2016 Leaf when the 2017

higher capacity leafs come out. Maybe able to find terrific deals on 2016's.

Also have 2004 Mini Cooper S that serves as our back up if needed.


your story smells a bit fishy... I would check out the blogs below. see what you think

as far as resets; I think part of it has to do with how much delta has to be recovered. I seem to remember anywhere from 3-6 weeks. nothing even resembling a few days though...

I just ran LeafSpy this evening, after charging the car to 100% (on L-1 as usual) to EQ the pack. Good news, actually. After getting a SOH of 89%, with 58.45AH, in the Spring after a Hot weekend, and then driving it for a Hot Summer, the SOH is now 88%, with 58.01AH and Hx at 87.68. At this rate when I turn the car in, even if it's next May 31, it should still read 12 bars.
