The following review has been posted for LeafSpy Pro. Can anyone else confirm that they have seen the SOH value displayed by LeafSpy Prohave a similar behavior?

Not very accurate I got this app mainly to check my battery and found it not very accurate, more like pot luck as to the reading you will get. It jumped from 97% to 89% back 100% and back to 89% over the period I tested. So a waste of money if you want it for battery checks. UPDATE: it's the SOH and telling me it does not happen is simply not true. I know others who have had same experience.

This was my response. As far as I know only Nissan service can reset SOH back to 100% either due to firmware update or replacement battery pack.

SOH comes directly from the Leaf and does not jump around. It changes very very slowly. It normally takes months to change 1%.

The only time it would go up is if you have taken your Leaf in for a firmware update and Nissan reset the SOH back to 100%. I that case it might change (drop) more quickly until it reached its previous value.
 
I've not seen this happening on the '13 Leaf SV I leased and returned, but I didn't have Leaf Spy Pro for long on that.

On the '13 Leaf SV I own, both Hx and SOH it doesn't seem to jump around significantly. They both seem to be in the 90 to 92% range each time I've looked.
 
Turbo3,

I have seen the SOH display either 99% or 100% recently on my 2015. I would not consider it to be "bouncing around" but rather just one digit change depending upon temperature, state of charge, etc. I am still running an older version of LEAF Spy Pro, but will upgrade when I get home and report results. I also notice that AHr and Hx vary a bit depending upon conditions. Lately, my highest AHr readings happen with battery about 50% SOC with lowest displayed after charging overnight. AHr readings can vary as much as 1 or 2 AHr during the day depending upon SOC, temperature, etc. This makes it difficult to determine if I may be seeing signs of slight capacity loss after 6 months and 10,000 miles.

In another thread here on mynissanleaf Someone said they had two different SOH% in leafspy. I wrote out am explanation of each screen and turns out they were looking at GID% in addition to SOH%. (see http://www.mynissanleaf.com/viewtopic.php?f=31&t=13371&start=400#p432988)

I'd have to wonder if it isn't a similar misunderstanding and the person is looking at kwh or gids instead of SOH%.
 
My SOH is 89% now and most of the time, but has dropped to 88%, gone back to 89% and increased to 90% before dropping back to 89%. The change has been slow, not jumping back and forth. I attributed the increase to warmer weather and slower charging, but that is just a guess.
 
my SOH varies as well but a MUCH smaller range (91-94) and over a much longer period of time. no more than a change of one in like 2-3 days at least mixed in with weeks at a time with no changes at all
 
On my 2015 S, I see SOH readings everywhere from 92% up to 97%. The AHr reading tracks rather closely with it as well, where SOH is roughly round(AHr/62.44, 0.01)

My numbers:

At least one other person with a 2015 has seen it doing similar things:

No offense intended but it'd be helpful to have screenshots of

11/10 - SOH: 94% AHr: 58.89
11/11 - SOH: 97% AHr: 60.53
11/16 - SOH: 93% AHr: 58

we could see all the values on those dates.

So if your SOH% jumps around did your HX or aHr jump too?

Was the pack hot or cold? Temps per reading might help?

Are there cell imbalances? Screenshots of cell voltages at low, med, and high SOC% might help?

If taking screenshots on a regular basis isn't your cup of tea try turning on logging and use the trip log results to post a more detailed log entry from files like Log_CT016156_cb3c1.csv and TripChrgLog_CT016156_cb3c1B.csv

I don't have anything anomalous so I'll trim mine to just a few columns but you'll see how steady the SOH and HX progress for my 2012 SL.

I keep all the data in a spreadsheet, and typically save screenshots for recording in the spreadsheet later...
Battery spreadsheet. AHr and Hx move together with SOH.

I haven't done a lot of screenshots besides after a full charge, but at a full charge, that is about typical as far as cell balance goes; as you can see from my data it's typically 18-22mV difference in cell voltage.

I get access denied trying to go to the 3 images. The spreadsheet worked though. Is that odometer column all 3 and 4 digits as in under 2,500 miles? Wow, must be, double digit charge numbers.

My car has around 2,700 or so L1/l2 and only 3 chademo charging sessions logged. So in addition to the miles you are doing a lot more high power charging cycles.

I'd say if you could charge closer to 2KW your readings wouldn't fluctuate as much. I'm assuming you pay per charge and don't have an adjustable rate EVSE?

Images should be fixed; though aside from showing the cell balance they don't give anything more than what's in the spreadsheet.

Yes, under 2500 miles; I've had this car for about 3 months now. Usually I do L1 charging only, the QCs are for the occasional longer trip where there's no convenient charging at the destination.

However, more to the point the SOH is "bouncing around" quite a bit as was commented in the review. So it definitely happens.

Agreed that is more to the point. But until we get a correction from the programmer of leafspy I'm going to assume that is something that is actually happening in the Leaf itself (the Car is to blame) not the phone app.
 
Tyger,

I typically discharge nearly to low battery warning (LBW) and frequently down into very low battery warning (VLBW) before recharging overnight at 240 volts. Once in a while I use public L2 charging for an hour or so if I need a bit more energy to get home. I notice the AHr, SOH, and Hx numbers vary more for a couple days after these partial charge sessions. If you are frequently plugging in for partial charges, that may be causing the variation you are seeing.
