BQ40Z50-R1: Learning Cycle Procedure for the BQ40Z50-R1

Your gg file seems okay.  Can you share your bqStudio log file? Thanks.

Hello Andy,
I attach a bqStudio log file while discharge cycle

discharge_1_1.83A.log
Thanks in advance.

The the battery is discharged to empty,  you need to have the battery relax for 5hours.  During the 5-hour relaxation time, did you ever see the VOK bit clear?

Do you have any log file that includes the 5-hour relaxation time?

Hello Andy,

I don't have any log that includes the 5 hour relaxation time, but the VOK bit is clear after 5 hours.

This picture shows you the Steps 5 and 6 of the learning cycle procedure, all bits need to changes are doing however Update Status can't update the value,

this value is 4 form the first to the last step of this learning cycle procedure.

I see the CUV is set in your screenshot.

Did the miminial cell voltage of all 4 batteres drop below the CUV:Threshold, which is set to 2500mV in your gg file?

I would need to see a log file for your entire learning cycle, in order to tell what might be wrong with your learning cycle.

Andy

I don't have a log file for my entire learning cycle, however I should update my learning cycle to 14 (update status)

Learning cycle can't want update more that one complete learning cycle (discharging and charging)

Hello Anthony,

Please provide us a log file, you will need to run this again. We also need the beginning gg.csv file or srec file for the learning cycle.

Hello Kang,

The gg.csv is enclosed. I also attached a discharge log (2 files)

As a reminder, I would like to créate a golder file, but it's impossible to update register update status more than 14.

However, I need to pass it to valid a learning cycle

2262.discharge_bug_status_14.log2110.discharge_bug_status_14_1.log7356.bq40z50_r1_v1_00_bms_bug.gg.csv

Thank you

I took a look at the two log files you provided. Neither of them is the right log file for the entire learning cycle. 

As Kang mentioned, I would suggest you run the learning cycle and provide a log file for the whole learning cycle.
