BQ34z100-G1 failed to learn

Other Parts Discussed in Thread: BQ34Z100-G1

Hi

I am currently trying to get my Bq34z100-G1 running.
I (hopefully) set all the settings for my system and I tried to start the IT algorithm.
I did all I could find on the web but unfortunately I was not successful.
The voltage and the current are calibrated and read correctly.
After the ITEnable command was sent I discharged it with about 30A (-7444mA in the log).
After this I let it rest for a couple hours and charged it with 15A (3778mA in the log).
The learned status was still 0x04, the SOC jumps while charging (sample 4265 and 8576 in the file) and while discharging (sample 4921 in the file)

The charging curve is a IUI curve (OK our charger is not perfect, the charging line is more like IUU, but this is not the topic here) (www.exide.com/.../Handbook, part 1, edition 6, Feb_ 2012.pdf site 75)


My settings:
24V 105Ah Lead Acid (2x12V Exide GF 12 105 V)
Sense Resistor: 1m
Scaled factor: 4

I attached a charge log, a discharge log and my settings

Can someone help me what I am doing wrong?
Which setting is not correct?

Thanks in advance
