As you have experienced, BMS battery balancing and recalibration can result in a updated evaluation of battery state. If it has been a long time, or a long distance since last time you discharged to around 10% and charged back up to 100%, the change can be significant.

The SOH is calculated using the mean of the two values indicating lost capacity: min and max det. I don't know if the calculation is the same as used by Kia, so the app may not produce the same SOH value as an official test at a Kia garage. That value is the goal for the SOH calculation in the app, but I need some app-recorded files with min and max det from shortly before and after a Kia SOH readout, as well as the official Kia SOH. I can improve the SOH calculation if I get a few such datasets, at different levels of SOH, and significantly different min and max det, like your car's values.

So on my soul battery SOC at 100% , SOC Prec = 58.72%. In my experience this represents an accurate estimation of the range I will get from the charge.

SOC Prec 100% = 150kms range (when new).
SOC Prec 58.72% = 88kms range now (what the GOM typically shows).

Of course, depending on my driving habits I can squeek up to 110kms out of the range, but typically no more than 100kms.

I am glad you find "SOC prec" useful. I haven't found and explanation of what this value from "PID 598" actually is, see https://docs.google.com/spreadsheets/d/ ... =234054559

So your guess is as good as mine. On a new car with 100% SOH, it seems to follow the SOC fairly well, so you may be correct in this value indicating the actual / expected amount of energy currently stored by the battery. I am interested in knowing more about the nature of "SOC prec" as well. Perhaps I should do some number crunching on the data I have gathered from my car 2017-2019, if I can find the time for it.

The SOH is useful for determining whether to visit Kia for a warranty check. But as you have demonstrated; you need to perform a BMS battery balancing and recalibration first: Kia will undoubtedly start by doing that, if you ask them to test the battery.

Ah I see. On my car I usually get to below 10% and back to 100% at least once a week. Every so often it seems to reset the min det value when this happens, which then slowly creeps back up as I drive/charge.

Well something doesn't add up, because my SOH has varied from 93% - 79% (and back, more or less) but my actual range when charged to 100% is much closer (consistently) to the 58.72% of orig. range value that Soc Prec reports.

If I take the car to KIA they'd have a hard time arguing that the battery range isn't below 70% of original, regardless of what the SOH calculation says (I would think).

In any case, this app has been very useful to me thanks for creating it. :)

Tested out the Soul EV Spy today, looking good. I prefer to use Torque Pro + custom dashboards, but this makes it easier for newbies to get the technical info they want. The info matches up exactly as Torque Pro (which makes sense because the data is all coming from the same PIDs)

How does my battery look? This a fully charged battery at 100% SoC.

This new beta version introduced an error that I never had seen.
I start the app normally, apparently it reads the values from the car, and disconnects itself after a few seconds. If reconnect automatically is on, it will reconnect and star the cycle again.

I notice this because of the message on the bottom saying it's connected or disconnected every few seconds.


What files do you need to troubleshoot this? :oops:

Please e-mail the soulspy... txt files from the Download catalogue to soulspy@evranger.com

Also a file from when it worked, If you have it.

Write which dongle you use, which car model and variant you have, whether the car was on ready to drive, on not ready to drive, on only accessory or off, what you did, and what you observed.

Then I can check.

Hello langemand, I already received your email, thank for reply.

Meanwhile, I also found something strange that is coming for a while, but only today I filled the spreadsheet, so I could only find it today.

Min cell deterioration and max cell deterioration are the same, in my case, cell number one.
Also this is just cosmetical, but deterioration is misspelled; it's written detoriation. :D
Can you guys see this images?

I checked your log files, the car reports 1 for both cell numbers, the app just display what the car reports:

I will fix it.

I will repeat: I don't know what the value in 'SOC Prec' is. The name was invented during the guesswork of finding meaning in the anonymous data values collected from the car.

Actual range is affected by many other factors besides battery capacity. Have you ruled out:
- hanging brakes
- New wheels or tires
- AC lost (most of) it's cooling fluid
- season of year (temperature, wind)
- changed driving patterns: Style, route, speed, distance per stop, time per stop, hills
- changed charging patterns
- roof rack

And the range value displayed by the car is varying even more, based on the latest trips (and, I believe, depending on when you last reset it).
