BQ40Z50: Fe-ion golden learning issue in BQ40z50

Other Parts Discussed in Thread: GPCCHEM

Hi there，

We have a Fe-ion solution, the fuel gauge uses the BQ40Z50-R1, but the golden learning is not successful.


In contrast to the learning of the LI-ion cell, the parameter settings need to be set in LFP_RELAX，what other parameters need to be set?

Or is it possible for the Fe-ion itself to learn successfully?

Thank you!

BR，Eason

    LFP needs a much longer relaxation time, you also need to make sure that your chem ID has been selected correctly. If not, please use GPCCHEM to do the chem ID matching. Only after that will you be able to successfully learn LFP cells.
