BQ20Z45: SOCC Perm Failure after Discharge Current

Mike Mrazik
Expert 1255 points
Part Number: BQ20Z45

Hello,

I have a a battery where I am testing three protection tiers:

OC Dsg, 20A for 2 seconds

OC Dsg, 37A for 31mS

SC Dsg, 95A for 0 seconds

While checking the accuracy of these tiers, I setup a CC load to be 36A, which would shut down in ~2 seconds under the 1st tier.  This did cutoff after 2.44 seconds as expected, but the pack would not come back on.  After hooking back up to the BQ Software, there was a PF for SOCC.  This failure appears to be charge current related so I am unsure how this is possible.

Thank you in advance for your help, Mike

    Are you sure your calibration is right? If your calibration is wrong, you may see the wrong flags trip. The easiest way to check calibration is to see if cc gain and cc offset are positive numbers.

    Hello,

    I know this pack has been calibrated, but the CC offset is -0.292 while the CC gain is 5.16.  Why does the CC offset have to be a positive number?  When I am discharging the battery at even 100mA, it knows it is in discharge mode (based on the Battery Status dsg bit), and the same goes for charge current @ 100mA.  I have attached the GG file for your review.  What is the calculation/equation that determines the CC offset being positive?  Is it possible that the integer wrapped around to some positive number? 

    Thanks, Mike

    Hi Mike,

    No, cc offset isn't wrapping. I meant cc gain should be positive. Your gg is OK. Can't find anything wrong there.

    Expert 1255 points

    Thanks for the help and for checking out the GG.  Any idea on where to look to solve this problem?  This is supposed to be a first level fault that is re-settable, instead it is getting a Permanent Failure for something Charge related.  I can't have a customer's unit do this in the field, the battery needs to protect itself and not cause a permanent failure.  I tried 2 separate packs and they both do exactly the same thing.

    Is it because the current variable is the size of an integer and cannot represent a current below -32A causing the variable to underflow triggering the error of a high charge current?

  • 0 in reply to David Jervis58
    TI__Mastermind 42535 points

    Hi David,

    Theoretically that sounds feasible due to overflow. But however, the moment his AFE sees that current, due to his setting, the current will cut off. So, in effect there's no way that the positive current can be seen. However, to confirm I'd like to see a log of your test with SBS logged at 1s.

    Mike,

    If you are going to use such high currents, please fake the calibration so that you don't run into overflow issues.

  • 0 in reply to Batt
    Expert 1255 points

    I can see what I can do about getting a SBS log of this, but I have a feeling that 1second wouldn't be fast enough.

    How do you mean fake the calibration?  Do you have any papers on this?

    No papers directly for this device, but what is mentioned here, www.ti.com/.../slua760.pdf applies to it.

    Hello,

    A couple of things:

    1) I never saw a response on the faking of calibration.

    2) Why would we need to fake the calibration due to using such high currents if the AFE would shut it down anyway?

    I have run the SBS log performing the following:

    1) Turn log on w/ attempted interval of 50mS.

    2) Started with no discharge or charge current

    3) Discharged at 37A which should trip the protection of 31mS.  This worked properly and didn't cause any Perm Failures.  Below is the current in blue, ~370mV across 10mOHM sense resistor = 37A and it lasted roughly 30-32mS.

    4) When the voltage came back ON (DSG FET turned back ON), set the current to 36A.  This caused the Perm Failure we've discussed (SOCC), but did cut off at the 1st tier protection setting (20A for 2 seconds).  Below is scope shot in blue, ~360mV across 10mOHM sense resistor = 36A and it lasted roughly 2.7 seconds.

    I have attached the .gg file (renamed to .txt) as well as the log.  If you look at the current in the log, it didn't register the 37A draw, and only registered the 36A draw as 32767mA.  Please review these files and let me know what you'd suggest for why we are getting Perm Failures for Charge Related items.  This is unacceptable in the filed to trip the protection setting appropriately but go into a permanent failure.

    Mike,

    This is going to take me some time to investigate. Expect to hear from me in a week or so.

    Thank you.  I apologize I missed the article you sent out on 7/27.  I need to understand what currents the AFE can shut off at for protection, and what currents are actually reported/stored in registers/etc.  Maybe this will get answered as you go through your investigation.

    How is this effort going? Have you had any luck on your side?

    Mike,

    Actually we're thinking this issue might be related to the CF failure as well. We managed to reproduce a partial failure of that (slightly different from the config because we used Ke24xx) but we did see the SOCC set. We'll need to further investigate and see what causes this.

    Mike,

    I'm going to close this thread. The CFETF thread will be used for this discussion as we think it's related.
