BQ27Z561EVM-011: GPC Report without my battery GG

Hello Chad,

This trend has been assigned and a response is currently being worked on.

Thank you,

Alan,

May I ask if there is any update regarding this question?

Hello Chad,

Although your GPCCHEM report is appearing to missing the list of other best matched ChemID's the best pick chemID in this instance would be chemID 3241. The only issue is that we recommend the max deviation % to be less than 3 %, thus meaning that I would re-check your setup and rerun the test to hopefully get a more accurate chemID that better match your cell. 

Thank you,
Alan

Hi Alan,

Thank you for your information.  During the time waiting for your reply, I actually using chemID 3241 for my system.  The mater of fact it is the default chemID.  However, with this chem ID, I have the charger plug in for more than 72 hours but the level of the GG return still only 85%.

I am completely lost and don't know where should I start for the trouble shooting.

Is there a way I can confirm if my charger and gg settings are correct?

I think it is most likely I didn't set up the GG correctly.

This is my screen capture of the bqStudio with my BQ27Z561 GG with chemID 3241, and "Average Time to Full = 5248 min" which is 87 hours.  Can you please give me some advice which parameter should I check for my 10Ah, 3.7V battery?
