BQ20Z45-R1_BQEASY-SW: BQ20z45 - Update status in learn cycle

Part Number: BQ20Z45-R1

HI

I'm trying to go through a package training cycle.

After turning on the QEN and going through the discharge and charge cycle,

the Update status has set to 06 and does not want to go to the 0E state.

The discharge was done with a current of C/5 and also C/10 with the same effect.

I'm sending a chip file for analysis

bq20z45 1.04.gg.zip

I don't know where I went wrong.

Regards,

Pawel Czezyk

    Hello Pawel,

    It is not critical for the gauge to get update status 0x0E, this indicates that a field Qmax has occurred in order to enable cell balancing. It will not impact gauging, and the field Qmax will happen eventually in the field.

    Sincerely,
