Original question:

BQ34Z100-G1 Learning Cycle

BQ34Z100-G1: no learning cycle plugin available in bqStudio / issues with ChemID programming

Part Number: BQ34Z100-G1
Other Parts Discussed in Thread: BQSTUDIO, , BQ27541-G1, BQ34Z100

Hello all,

I am currently setting up the bq34z100-G1 for gas gauging of a LiFePo4 battery pack. When programming the ChemID with bqStudio 1.3.86, I see the below warning message. Can you please let me know what needs to be done?

Furthermore, I don't see any controls for the manual/automatic learning cycle (as it is available for bq27541-G1 for example). Is there a way to perform the auto-cycle for the bq34z100 as well?

Thanks & best regards,

Daniel

    Hi Daniel,

    Please check if your fw version for the bq34z100-g1 is v0.16. If it is not, please update to it by downloading the fw from the product page. The bqz file that comes with it in the package needs to be copied to c:\ti\batterymanagementstudio\config.

    Once that is done, this warning will go away.

    Thanks, Batt!

    I verified the FW version (v0.16) and copying the bqz file to bqStudio's config folder indeed fixed the misterious warning message. Thank you!

    To the second part of my question:

    I noticed, that besides the learning cycle plugin also the GPC packer plugin is not availabe if the bq34z100-g1 is selected. Can you please let me know if this is intended behavior or if this is a bug which gets fixed with a future bqStudio revision?

    Is there any other TI software available which I can use to automate the learning / optimization cycles?

    Thanks & best regards,

    Daniel

    Hi Daniel,

    Unfortunately the plugin is not available. It's still in internal debug as it had many issues. There is no software to automate learning cycle. But you can easily write a script to automate your sourcemeter and load to perform it for you.
