Ahr is no better. Go back a few posts and look at the screenshot I posted. Almost 38k miles, and "like new" Ahr.

When I looked at your screenshot, my brain read "56" not "65", so I thought it made sense. But I was obviously wrong! Maybe you've stumbled on a way to bring back battery capacity. :?


No. Yesterday's numbers are 60.49AHr, SOH 92% Hx 92.82% 39,535 miles.

Based on trends and a recharge test a few months ago, I think the battery is down 10%. Plus or minus a few percent.

The thing to remember is that you are looking at the car's estimate, which can be in error both ways by at least a few percent even if you don't take long trips with multiple QC sessions. Temperature, driving habits, charging habits can all change the estimated capacity, and I don't think will change the actual capacity of the battery by much.

Is there any statistics, at what capacity of the battery (or at what SOH) will the 12th stick of battery capacity light up again?

I don't know of any. It doesn't matter anyway. Even if it comes back, it seems to eventually (in the near future) go away again, permanently.

My 12th bar went away near end of Nov 2017 when SOH was down to 83% (viewtopic.php?p=511915#p511915). I've not once seen it come back, even if my SOH rose to 85% or so.

Re: Leaf Spy and Leaf Spy Pro

I am trying to automate charging my Leaf to only 80% using my home Openevse.

Here's what I have:
USB dongle (whatever it was that was recommended with Leaf Spy).
Leaf Spy Lite (but I'll be buying Pro if it can help me on this)
Openevse EVSE unit
Wifi board for Openevse.

So on my phone I have the SOC information (in Leaf Spy), and the ability to connect to the Openevse and set the KWH charge limit.
What I don't have is a way to communicate between Leaf Spy the Openevse web page, and do the little bit of math necessary to convert current SOC into the appropriate charge limit instruction.

Has anyone already tried something like this, or any other way to automate the 80% charge limit?

I should add that while I am not facile at Android app development, I am a professional software "engineer" (I cringe whenever I hear that) and am comfortable with learning new technologies.

Thanks

I had suggested to someone that potentially had more time on their hands that was working on OpenEVSE that they add a Bluetooth module and have the EVSE itself connect to the vehicle's OBDII adapter and control charging directly within the EVSE itself. This is probably the best solution to the problem, but involves hardware/software mods to the EVSE.

Your suggested approach would likely either require a modification to LeafSpy itself to dump charging data somewhere where you could read it (I'm not sure if the dropbox integration is "live" during charging or whether it dumps data from a charging session at the conclusion of charging, or if it even dumps that stuff to dropbox at all (sorry, I haven't played with that aspect of the app much).

Another approach using LeafSpy would be to take advantage of the fact that it does dump data into the Android file system. I suppose you could write a second app that monitored that and then sent a signal to a server you control that would then send a signal to your OpenEVSE.

But if it were me, the approach I would use would be to just use the LEAF telematics (assuming that's not an issue for you with respect to TCU upgrades and cell coverage). When you are charging you would kick off a program that requested SOC from NissanConnect. 15 minutes later you would send another request and from there estimate how long until your vehicle reaches 80% SOC. If you wanted to get precise, you could time several more requests just before that time to get it precisely at 80%, but it's probably not that important to get it that close. Once you detect an 80% (or close enough) SOC, your program then sends its signal to OpenEVSE to halt charging.

Reposting here as didn't spot it:

Hi all

I have a late 2014 Leaf Tekna, an iPhone 8 Plus, LeafSpy Pro version 1.6.28 and the following OBDII Wifi Dongle: https://www.amazon.co.uk/Pumpkin-Interf ... lm327+wifi

I have followed the instructions for wifi by manually setting the IP and subnet in loads of different configurations including automatic but can never get LeafSpy to connect. I am a software developer by trade so feel I have totally let myself down as I am usually "the fixer" for other people :D

I have also selected the ODBII connector in the settings and registered it.

Here are some images of the different settings I have tried. I only ever get Retry ELM 11 in yellow in the corner. Am I doing some stupid or is there an issue with my dongle?

You need to take an ELM trace (see bottom of help file for how to do it) and send it to me.

From hanging at state ELM 11 it looks like this WiFi adapter does not support the needed commands.

An ELM trace will confirm that.

This is the OBDII adapter I recommend for iOS and Android. They ship worldwide.

There is a bug in the just released version of LeafSpy Pro 0.41.109 that crashes the app if you try to save an Elevation/Speed graph.

Will fix in next release once I find out why it is crashing.

=======================
One more bug. Don't select BSM only or MTR/INV as your model year on settings or it will also crash the app.

This one is an obvious bug I put in at the last moment with code to support the 2018.

=========================

Version 0.41.110 is being released to fix these two problems.

With 0.41.108 (and 0.41.109), LeafSpy Pro has started to lockup my OBD-II adapter again. It seems to work if I enable "slow transfer mode", but that setting doesn't appear saved. I can generate a trace if you'd like.
