BQ28Z610: Can't find SOH Load Rate in BqStudio

Part Number: BQ28Z610
Other Parts Discussed in Thread: BQSTUDIO,

Hello,

My customer is trying to set SOH Load Rate in the 2610_0_17-bq28z610.bqz setup of bqStudio. We can't seem to find the SOH Load Rate setting in the GUI. I was able to find it in 2610_0_20-bq28z610.bqz. Can you point me to it in the _17 setup?

_17:

_20:

Thanks,

Michael

    Hi Michael,

    As far as I can tell, the SoH Load Rate doesn't exist in the v0.17 firmware. Here is the what I see the ReleaseNote for v0.20 

    ===================================
    bq28z610 v0.17 (build 21) Alpha
    ===================================

    Changes:
    - Simplified SOH calculation to be FCC/DesignCapacity

    I would suggest your customer use v0.12 firmware instead if they want to make use of the SOH Load Rate setting.

    Hi Andy,

    This is a little confusing. In the TRM, it talks about an "updated" and "previous" version of the device. And then it says the "SOH Load Rate can be set to the typical current of the application". So can SOH Load Rate be added to the v0.17 firmware? Or is the only option for the v0.17 to be SOH = FCC/DesignCapacity? Because it looks like the TRM says that's not a good method. 

    Thanks,

    Michael

    Hello Michael,

    Yes, the TRM will need to be updated. I have started an email internally on this.
