BQ30Z554-R1: 2S pack learning cycle, but only Cell 1 Ra table gets updated- Update status 05

Hello Subrat,

Can you share the log data from the test along with the .gg configuration file?

If the cell did not have a high enough voltage drop from the expected DOD point it may disqualify it. Also if it calculates a negative Ra value it will disqualify the Ra table updates.

Sincerely,

Wyatt Keller

Attached is the gg file and log data from learning cycle

Hi Wyatt,

We ran learning cycle on 25 packs. 22 battery passed the learning cycle successfully.  Out of those 25 packs only 3 of the packs failed the learning cycle. All 3 of the failed packs has the same issue, no update on cell_0 Ra table. The schedule we are using as of now is Discharge current of C/7 (as recommended in TI App note ).  Do you think current is the only issue here or is there something else you observe from the data log. Please let me know.

Sincerely,

Subrat
