Replacing the single cells in the battery pack?

This is surprising to me, the OBC version is earlier than the one it should have according to the stickers.

The sticker on the EPCU is the correct one for your original car. 12.2E
That you OBD now has a sticker 11.1E suggests that they put in a re-manufactured old box to replace the failed original one.
Most people got a completely new box when their OBD failed. But this is an expensive option if all you need to do is re-solder a burnt capacitor. This is the first example of that cheaper option.
Obviously they would flash newer software onto the OBD chip so you won't have an old software version.

I see 2018 05 19, it’s not easy to see

I’m not sure, but OBD dongle would get the informations from OBC, not directly from BMS?
Car Scanner is reliable App, has great range of options and I did connect it to my car from the new phone after putting replacement battery. I guess that it’s recognizing my car’s OBC as the original 2015 Kia EV, regardless what battery I have now. And it’s definitely 2018 on the yellow sticker, BMS has for sure all cells voltages if it’s originally put together. Then must be that OBC can process only 96 cells due to the original programming.
It’s all guessing, I wish that I made few more photos before assembling it to the car

okay - my bad eyesight. So it isn't a new set of cells.
You are totally wrong though about the way OBD apps work.
If you want to know more try looking for my codes for using Torque Pro. Or read through the original Soul Spy thread. ( Not the same as the SoulEVSpy app thread. )

I don't recommend any OBD app anymore because they have no ability to adapt to changing algorithms within the car that occur each time Kia flashes a new update. If you want to do it properly you have to write your own codes for your own car. It is much easier now than when the car was new because most of the codes are the same or similar. However the one code that is most relied on by average users SOH is the very one that Kia changes the most.
I just noticed an example from yesterday :- Soulspy is not working anymore after i got an BMS update.

Thanks Jeju,
I guess that makes sense to focus on SOH if you are owner with the warranty still in place.
For me it’s irrelevant, no warranty, no possible claim,
I’m more interested in cell voltages fluctuations during my trips, battery percentage drop for the same trip with how many kWh I can charge in to battery for the same span in percentage. This will give me my data for comparison once I have to do some DIY.
In 4 weeks since my battery swap, I made around 2400km, average consumption 19kWh per 100km, it is winter now and Switzerland is not well known for its beaches .
All cells are behaving in uniform manner, none is being temperamental for now.
I’ll continue keeping eye and compare every month my data, but it’s obvious that in spring my range will go up and my consumption per 100 go down.
