BQ34Z100-G1: Battery Management Studio 1.3.80 learning cycle tab problem

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

Hi

I am using battery management studio(1.3.80) for bq34z100-g1 and ev2300 . I want to use learning cycle but there is no learning cycle tab in the toolbar. 

Can you say why learning cycle tab has not been seen in the battery management studio.

I really appreciate any help you can provide.

    Hi Shir,

    Unfortunately, the learning cycle tab was not included in the tool spec for bqStudio with respect to the bq34z100-G1. I have sent your feedback to the tools team with a request to add the learning cycle tab to the toolbar.

    For the time being, the learning cycle will need to be performed manually. If you have any questions about that process, please let me know!

    Sincerely,
    Bryan Kahler

    Hi Shir Hussain Ahmadi,

    Here is a general guide to the learning cycle (written for another gauge): www.ti.com/.../slua597.pdf

    In general:

    0. Configure dataflash, pack chemistry, perform calibration and export GG File (for later comparison)
    1. Enable IT
    2. Send Reset command (0x0041)
    3. Charge the pack to charge termination.
    4. Rest until the OCVTAKEN flag sets
    5. C/10 Discharge to the termination voltage
    6. Rest until the OCVTAKEN flag sets. At this point, QMax should update and the Update Status should increment to 0x05
    7. Charge the pack to charge termination
    8. Rest until OCVTAKEN flag sets
    9. C/10 Discharge to the termination voltage
    10. Rest until the OCVTAKEN flag sets. At this point, the Ra table should update and Update Status should increment to 0x06

    Sincerely,
