BQ27531-G1: New Learning Cycle

Part Number: BQ27531-G1
Other Parts Discussed in Thread: BQ24192, BQSTUDIO

Tool/software:

Hi Anthony,

changing the BYPASS Bit to 1 allow the setting of the bits CHRG_FAULT[1:0] to 11, indicating on this way timer expiration as desired.

But as i said in my previous message, our application goal is to let entirely the gasgauge to control the charger bq24192 which is not possible in case the BYPASS is set to 1.

So when the GasGauge control the charger, this fault will be blocked and there is no way to find out. Correct?

    Hi Alexandru,

    After discussing this issue with our firmware team, I believe this is the case.

    Hi Anthony,

    we have than here a problem.

    We use the gasgauge and the charger in a medical device and safety is a big issue.

    I made further tests and even the charger in fault case, is NOT showing it at STAT pin. This should also not happen.

    Do you see any possibilities to remove the bug and to get a new FW?

    Is possible at all to update the chips? We buyed already 3000 pcs of both for assembly.

    Regards,

    Hi Anthony,

    i made a temperature test (between at -5 and +50°C) with our device where gasgauge control entirely the charger. The bit GG_CHGRCTL_EN was set in FLAGS. In the HOT phase at +50°C (the charging was already stopped and the battery temperature was 61°C ) the battery voltage has increased to 4193mV. Some time latter (1-2 sec.) the GG_CHGRCTL_EN bit was disabled. From this time the charger was not controlled anymore by the gasgauge. 

    Is any explication for this behaviour?

    Is STAT above referring to the CHG_STAT of REG8 or a different STAT value?

    Have any protections been triggered by the gauge when the cell reached the higher temperatures? Do you have a log file depicting the situation above so we can take a deeper look?

    Hi Anthony,

    with STAT I mean the pin of the bq24192, which in case of a fault  should blink, but unfortunately is not hapen in case the timer expire.

    I hope a firmware update exist in process.

    I think the Overvoltage protection of the battery has triggered which is set to 4.25V, but I'm not 100% sure. Unfortunately I have no logged file.

    Hi Alexandru,

    Since the Overvoltage protection and STAT pin are controlled by the charger, I will loop someone in from their team for their input.

    Hi Alexandru

    Checking on the BQ24192 issue and will have an update early next week.

    One thing that would help -- What is the value of REG07?

  • 0 in reply to Bill Johns
    Intellectual 495 points

    Hi Bill, Hi Anthony

    the value of REG07 is 0x0B.

    But now an additional issue has appeared.

    We made a test with charging/discharging to see how good the the SOC will be displayed. This value we use in our application to decide when our device need to be shut down due to the lack of capacity.

    From the picture below you can see that although CellPackVoltage is reaching the value of TerminateVoltage (3V in our case) the SOC value remain blocked at ca. 78%. 

    The TrueSOC is going down but not the SOC. Do you have an explanation for this behaviour?

    Hi Alexandru,

    Regarding the SOC issue, would it be possible to share a log file so we can take a look?

    Hi Anthony,

    Concerning blocked SOC I can share with you our own log file for the last 12 hours (it is similar to bq log file only that it miss some columns).

    Here is the file (CSV format): 

    TR_0000000037_epi_026_VG5_MISC_DATA_FROM_WD.txt

    The SmoothEn Bit in OpConfig C register was set to 1.

    Hi Alexandru,

    Understood, I see that the log file sent was taken at the beginning of a charge period. If possible, I would like to look at one of these relax periods after charge where the TrueSOC is falling but the Reported SOC is not. Since the TrueSOC relies on the Unfiltered FCC and RemCap values, this makes me believe that these values are still changing during this relax period.

    Regards,

    Anthony

    Hi Anthony,

    please check the row at the DateTime 17.08.2024 21:21:12.

    It shows how the value of TrueSOC change to 0 and how the SOC drop from 73% to 0%. From this time SOC is not blocked anymore!!!

    Hi Alexandru

    Quick update -- I have been looking into the BQ24192 not blinking fault issue.

    We have not been able to duplicate the problem yet but still checking on it. We see blinking for OVP and TS fault in lab.

    Thanks for info on value of REG07, thought this was related to a known problem BUT that does not appear to be the case.

    Will send another update by end of week.

    TI__Mastermind 28440 points

    Hi Alexandru,

    Thank you for sending the log, I believe that the True SOC is dropping because there is still a discharge current being applied at this time:

    However, regarding the reported SOC, I believe this value is dropping from the constant value to 0 due to the smoothing algorithm, where the gauge will update all of the passed charge in a relax state once exiting the relax state. However, with the discharge still occurring, the gauge should not be in a relax state, in turn the smoothing algorithm should not be active at this time. Can you please tell me what the Quit Current Parameter is currently set as?

    Regards,

    Anthony

  • 0 in reply to Anthony
    Intellectual 495 points

    Hi Anthony,

    The value for Quit Current is set to 30 mA. 

    I'm just wondering why the SOC remain at a constant value although TrueSOC is dropped as expected during the discharge phase?

    Our test aim is to see how accurate calculate the gasgauge all the values (SOC, RM, FullChargingCapacity, etc processed by our App) when NOT a complete (100%) charge/discharge cycle occur. We want to check how it behaves when small charge/discharge cycles occurs (for example 30% discharging, 20%charging than next10% discharging and 15% charging and so on).

    Hi Alexandru,

    Alexandru Mixich said:

    I believe that something might be triggering the smoothing functionality at this point where the SOC remains constant, which is odd because the gauge does not enter relax at this point where it should trigger. However, it is difficult to determine what is causing this since the sent log file does not have the full set of register readouts from the device.

    Regards,

    Anthony

    Intellectual 495 points

    Hi Anthony,

    from which other register you will need the readouts? 

    Our workaround is to deselect SmoothEn bit in Opconfig C. Since we did this, we have not registered any anomaly more. Is this the way we should follow?

    I think this should work as a workaround, however if there is a standby current applied during relax or a large jump in temperature, the SOC will most likely move much more since the unfiltered values are being used. If these are situations not normally seen in this application, then I believe it is ok to use the unfiltered values.

    Hi Anthony,

    i'm faced with a new issue now.

    During relaxing phase, after fully charging the battery (the FC bit was set) suddenly the charger has started for a short time, 5 sec. (the time period is marked in yellow in the Excel file, Date 09.09.2024, Time 12:29) to charge at 4200 mV. But this is unwanted due to the saffety reason and it should remain at 4100mV as defined per temperature profile. Also the SOC was set to 100%

    What can be the cause for this behaviour?

    Regards,

    TI__Mastermind 28440 points

    Hi Alexandru,

    Once 100% is being seen from the SOC at 4100mV, is the charge being disabled using the CE pin of the charger? When this new charge appears, is there a way the CE pin is becoming enabled again?

    Regards,

    Anthony

  • 0 in reply to Anthony
    Intellectual 495 points

    Hi Anthony,

    the CE pin of the charger is all the time LOW. (see the attached schematic)

    It is possible that the communication between the charger and gasgauge has been interrupted for a short time and the mode has changed from Host to Default? That could explain why the voltage has chaged to 4200mV (this is the default value in REG04) and the charging has started althogh the FC bit was set. What is your opinion?

    Regards,

    Hi Alexandru,

    Please allow me to get our charger team's opinion on if stopping the communication to the charger can reset these values.

    Hi Anthony,

    i've provocate a communication error on the I2C lines between charger and gasgauge and i was able to reproduce the issue and confirmed on this way my assumptions written in my last message. To generate this case i've short circuited both communication lines for few seconds.

    Attached the log file taken with bqstudio.

    This pair of components formed  by the gasgauge and the charger seems to have many curiosities. 

    The most important thing for me is the issue that the charger is not blinking in case of  a fault (charging time has expired). Can you ask the charger team if they could reproduce this and what kind of a workaround can be used.

    Regards,

    Alexandru Mixich

    Hi Alexandru

    The Charger Team is checking on STAT pin not Blinking for a fault, OVP and TS.  This is working in the lab we see STAT Blinking for a fault.

    Trying to identify a that would cause it not to Blink.

    Just to double check, you are using a BQ25192 and not a BQ25192I?  This 192I will not blink during fault

    Hi Bill,

    we use bq24192, without I, together with bq27531G1. If i use bq24192 alone everything works fine. I have the problem when the charger is controlled by the gasgauge.
