BQ28Z610: Bq28z610 Learning cycle "Charge Battery to Full" problem

Part Number: BQ28Z610
Other Parts Discussed in Thread: BQ78Z100

Hello, 

I am trying to learn how to do a learning cycle bq28z610 with 2 cell configuration using APR18650M1 (1100mAh) batteries with EV2300.

1st) ChemID was configured.

2nd) Calibrated current/cellvoltage

3rd) Discharged:

I was able to discharge the batteries by:

1) Enable "Fet_EN" & "Gauge_EN" + "RESET" in command

2) At the end of discharge IT Status (low) - REST bit was set

To charge batteries:


1) Enable only "Gauge_EN" & apply 7.4V (1A) Charge to VPack+ & Vpack-

Issue:

1) FC bit never sets. Only FD bit is set after discharge.

2) Charging Current only shows 88mA

3) Charging Voltage shows 8200 mV. 

I'm not really sure what needs to be configured or changed. 

I've included gg.csv file for the configuration I currently have.

Thank you in advance for the help

    Mingyu,

    I don't have your gg file in the post. 7.4V is not a proper charging voltage. 8.4V is. I suspect your config is wrong or your charging voltage is wrong. FC will set only after you reach primary charge termination. At 7.4V you will not. Charge termination opens at 8125mV per defaults and your current has to be less than taper current for 80s. Hope this helps.

    Hi Batt,

    I've uploaded the gg file for the configuration I have currently. 

    Here are some extra questions I have for you:

    1) Which configurations are "mandatory" before proceeding with learning cycle?

    For example: taper current/discharge current/etc.

    2) If I set taper current to be 10% of fast charging current for my battery (400mA), what should I set my discharge/charge/quit current?

    3) Does the "Fet_en" & "Gauge_en" have to be set for charging or just "Gauge_en" shown in "How to Complete a Successful Learning Cycle for the bq28z610/bq78z100" 

    Thank you in advance for the help.

    Can you please send me the gg.csv file as an attachment? It's difficult to read it this way or import it and test it.

    Hi Batt,

    It keeps giving me an error when I try uploading gg.csv file. What other ways can I send it to you?

    Hi Batt,

    I decided to convert the file to Excel. Hope this works. 

    Thanks,

    Please don't convert it to xlsx. Please upload it as a zip file.

    Hi Batt,

    Here's the file I have right now. Thanks

    Hi Mingyu,

    It seems you are just using our default config for the most part which is accurate for 4200mV cells.

    So given that to answer your questions,

    1) Which configurations are "mandatory" before proceeding with learning cycle?
    You need to have completely discharged the cell after correctly programming the gauge per the app not instructions.

    Adjust taper current to 1/10th of the C rate.
    Your charge and dsg current can be C/2 and C/5 respectively.
    Your Term V should be about 3200mV or 3000mV.
    You should dsg your battery to 2900mV to ensure that term V is hit during dsg
    During chg you should taper to at least 20mA below your taper current and keep the current on that level for at least 80 seconds

    For example: taper current/discharge current/etc.

    2) If I set taper current to be 10% of fast charging current for my battery (400mA), what should I set my discharge/charge/quit current?
    Quit current should not be changed. For the rest, see above.

    3) Does the "Fet_en" & "Gauge_en" have to be set for charging or just "Gauge_en" shown in "How to Complete a Successful Learning Cycle for the bq28z610/bq78z100"
    You need to have fets enabled for charging. Therefore send commands 0x21 and 0x20 for GAUGE_EN and FET_EN.
