BQ40Z50EVM-561: BQ40Z50R2

Prodigy 80 points
Part Number: BQ40Z50EVM-561
Other Parts Discussed in Thread: BQ40Z50, BQSTUDIO, BQ4050, BQ40Z50-R2, EV2400

I am running a test to see how accurately the BQ40Z50 can track the battery capacity. This is being done after we have done a ChemID and learning cycle. 

The problem is that the BQ chip does not seem to update the SOC during the discharge periode. The battery is being charged at about 500mA and discharged at about 20 to 30mA. This current is not constant but rather pulses of 60mA at a rate of about 2HZ. How can we get the BQ40z50 do this.

    Hello Bruce,

    This is a very bizarre load profile compared to most applications, since you are switching modes so often between charge and discharge I would decrease the Chg Relax Time and Dsg Relax Time so they are both 5sec or less. Also it looks like the origins may be due to one of your settings for the smoothing engine - this can be seen by checking the true and filtered RemCap values in your log, I would try enabling the Relax Jump Ok bit.

    Sincerely,

    Hi Wyatt,

    I have attached some picture of the current profile that we are trying to measure. The load is an electric fence and the charging is done by solar panel. The reason for running the test of 4 hours of load and then a short charge at 500mA is to get a feel if the gauge can work with not ever reaching full charge or discharge over a number of months. The data in the previous log was us allowing the charger to partially charge the battery to a set voltage so that it is never fully charged or fully discharged.

    When running with  DC load I see that when the load current drops to 7mA the RemCap stops updating. As you can see from the graphs attached our current is very lumpy going from 55mA to zero every second. In one case the average is 20.22mA and in another case it is 7.37mA. This is to conserve the battery when it is getting very low.

    In the attached LOG file the avarga current is being reported at 50mA approximately the RemCap is still not being updated. I think I have made all the changes you suggested but it still does not seem to be working.

    Hello Bruce,

    Can you also try disabling the OCVFR feature, in your log the bit is set. I think the main thing is setting up the relax times and the chg/dsg thresholds properly may be causing the issues during constant switching. If you change the charge threshold higher than your small pulses so the gauge is only ever in discharge or relax does this behavior occur? If the gauge remains in relax mode it will only ever update RemCap when an OCV is taken, and if you're in OCVFR that will not be for a long time - 48hr lockout in the flat region.

    Sincerely,

    Wyatt Keller

    Can you increase the sampling frequency? It looks like you're taking samples every 30sec. I'd like to see what's happening with the registers on a faster scale. It should allow you to do around every 4 seconds.

    Hi Wyatt,

    What are the conditions where the coulomb counter stops updating the RemCap. The pulse is rather short so there is a lot of dead time. Also what is the coulomb counter sample rate when active and when asleep.

    Hi Wyatt,

    Just seen an interesting thing and wondered if this is of any help. After the creation of the SREC file I had to restart BQStudio. Once it had booted I noticed that the indicated capacity had suddenly dropped to something that I was expecting it to be and not the 90 something it used to be showing. I made a short log file as soon as I could and it is attached.

    Hi Wyatt,

    I have been running a log over the weekend. If I take the average of the AvgCurr for the discharge period of 4 hours I gat an average of 55.7mA. Multiplying this by 4 (the discharge time) I get 222mAh. This is approximately the same as the mAh added back to the battery to bring it back to the same state of charge as it was when the discharge 4 hours started. I just cant understand why the BQ40Z50 does not use the AvgCurr it is measuring to calculate the amount of charge taken out of the battery. It is reading the average current correctly but then not using it.

    Hello Bruce,

    The gauging algorithm can be complex depending on your mode, Impedance Track does not only use coulomb counting, it uses voltage based corrections within the chem ID during low current  states and depending on the smoothing settings it will not coulomb count and it will only rely on the voltage for SOC correction in relax. 

    I will need some time to run your data to see what may be occurring, I will try to have some feedback within a couple days, we are trying to catchup after the holiday.

    Hi Wyatt,

    Ran a test over the weekend and found that if a put a very large filter (40,000uF with 4.4mH) I can get it to work. This is not practical from a design point of view. I notice that with this very large filter the current never goes below about 10mA. Not sure if this is of any help.

    Hi Wyatt,

    Attached is a quick drawing of the test setup and the logfile. Hope it is of some assistance. I tried using less capacitance and also less inductance but found this t be the minimum.

    Due to the fact that the system will be running unattended and from experience, we have found that in the winter the battery may never get fully charged or discharged for months on end, we felt it was best to use the BQ40Z50 as opposed to the BQ4050 to get the advantage of impedance tracking to help with battery aging.

    There does seem to be an improvement as per the attached files. I will keep the test running for a couple more weeks to see if the upward trend ofthe RemCap is going to settle down to a nice flat curve.

    I do note that the Cell Balancing does not seem to be working, have I done something wrong.

    Hello Bruce,

    This does look like improved performance.

    If you just uploaded the data to the gauge after upgrading to the R4 firmware it will need a Qmax update before calculating the cell balancing properly, it looks like that may not have happened before your test started since the DOD0 values are 0.

    Hi Wyatt,

    Thanks for the explanation, I will do a Qmax update and continue testing.

    I only have one more question about the versions of the firmware. Why do TI ship all the EVM modules with the old version. As the default version seems to have been release in 2017.

    Bruce

  • +1 in reply to Bruce Morris
    TI__Guru** 105590 points

    Hello Bruce,

    We actually don't ship any hardware past BQ40Z50-R2, all the other firmware releases must be uploaded during production using the SREC or flash stream files with the golden image. And for the EVM you should already have access to the EV2400 for setup of the gauge so changing the firmware only takes a few minutes.

    Hi Wyatt,

    We are testing both the BQ4050 and the BQ40Z50 and notis that both of them seem to have a Zero error on the coulomb counter. Looking back I have shared what the wave shape looks like. It seems that the average current for the time spent below 10mA is about 1mA. This would explain the error we Are seeing in the creep in RemCap. How is the zero for the current sensor done.

    Bruce

  • 0 in reply to Bruce Morris
    TI__Guru** 105590 points

    Hello Bruce,

    Depending on the gauging algorithm used will determine how the gauge increments remcap. CEDV does not use any voltage corrections and relies on coulomb counting. Impedance Track uses voltage for corrections in relax state and has much more advanced smoothing engine than CEDV.

    Sincerely,

    Wyatt Keller

    Hi Wyatt,

    Our product never has a relax period so by the sound of it we are totally reliant on coulomb counting. What we are seeing is about a 1mA positive offset on discharge in comparison to charge. Is there a way to correct this. We are seeing it in both BQ4050 and BQ40Z50. How do these chips Zero the current sensor.

    Based on that you have said above it seems that as we do not have and relax period we may as well use the BQ4050 as apposed to the more expensive BQ40Z50. Is this correct.

    Bruce

  • 0 in reply to Bruce Morris
    TI__Guru** 105590 points

    Hello Bruce,

    You can add a board offset value to help counteract any offset with the system. They short the SRN and SRP lines internally to get calibration values.

    The BQ40Z50 does have better gauging, but if you can never get an OCV then the error will accumulate with Impedance Track.  Depending on your application CEDV may be a better option. Accuracy will get worse with time though since it doesn't do any learning.

    Sincerely,

    Wyatt Keller
