Original question:

BQ34Z110 and BQ34Z100-G1 data reset when battery is replaced.

BQ34Z100-R2: Do we need to re-write Golden Image after replacing a battery pack with a new one?

Tool/software:

Hi team,

  1. I wonder if one needs to re-write the golden image after replacing a battery with a new one. (same chemistry, capacity, characteristics, etc).
    1. Note that our system does not yet provide the conditions to help the battery reach the lowest DoD through continuous discharge, which I understand is necessary to learn the proper full capacity. The pack is large enough and there is a constant charging source working in the daytime.
  2. Is a full reset necessary after battery replacement?

Regards

Ali

    Hi Ali,

    Yes, please reflash the golden image upon the replacement of the battery.

    I recommend sending a reset cmd to verify all data has been written properly to data flash.

    Regards,

    Hi @Evan,

    I just want to clarify, are users never supposed to replace batteries then? Or they're supposed to hit a "battery reset" button when they do? 

    I'm a little confused as how its supposed to be used. It seems like we're not following how TI anticipates the product to be used, and I am not clear what that is.

    Hi Lucas,

    You can replace the battery, upon replacing a new battery please reflash the golden image, the reset cmd afterwards is to verify that the file was flashed correctly but is not necessary.

    Regards,
