bq40z60 Learning Cycle

Other Parts Discussed in Thread: BQ40Z60, BQSTUDIO, BQ2947

We're trying to get our bq40z60 up and running with bqStudio. We're finding it particularly difficult to get the learning cycle going. Is there a "learning cycle guide" available?

The main annoyance is that bqStudio's names for registers do not always line up exactly with the names printed in the reference manual. To make matters even more confusing, the register locations given in the advanced view do not line up with anything that I can find in the reference manual.

For instance, RDIS must be set to enable the learning cycle. However finding where I can set that register in bqStudio has taken more time that I care to admit and I still struggle to find it on subsequent runs.

Once the learning cycle claims to have started, the output FETs are not enabled. I've been able to enable them in the past with some combination of sending FET_EN, CHG_FET_TOGGLE, and DSG_FET_TOGGLE. Now however even that is not working. It looks like the FUSE output is enabled and preventing DSG/CHG but I cannot figure out why or how to clear it. I've tried sending a "Fuse Toggle" command via 0x001D manually but bqStudio reports communication errors (only for manual SMBus commands).

    Hello Cameron,

    Sorry for the confusion. Let me review all your concerns above and get back to you in a day or two.

    Hello Cameron,

    Once you have your board setup, bqStudio and communication verified (seeing cell voltage updates in bqStudio, etc); you're almost ready to start the learning cycle. Click FET_EN button in the Commands tab to enable the CHG and DSG FETs. If you have communication issues in bqStudio, clicking RESET button in the Commands tab help re-establish communication. You will then setup your settings, protection and gauging parameters. R_DIS flag will set until a valid Qmax update is made and a valid OCV reading then it will be clear and Ra table will be updated on subsequent discharge.

    1. Discharge battery to 0% with C/5 to C/10 until Termination Voltage.
    2. Issue a “Reset”.
    3. Wait 30 minutes.
    4. Charge battery to 100% with C/2 to C/10 until taper is reached and valid charge termination is reached.
    5. Wait 2hrs (R_DIS should be cleared during this relax time).
    6. Discharge to 0% with C/5 to C/10 until Termination Voltage (Ra Table should update during this discharge).
    7. Wait 5 hrs.

    Thank you for your reply. Unfortunately, this does not quite answer my questions and confusions.

    1. It seems FET_EN button/command is really a "toggle" for the FET_EN bit in "Manufacturing Status". I'm assuming you're saying I should ensure the FET_EN bit is set (red box in bqStudio)

    2. Does the learning cycle do software control of the CHG and DSG FET outputs? Some reading suggested you were supposed to use the manual CHG/DSG FET controls for the learning cycle. Please correct me if I'm wrong here.

    3. I'm still unclear on which "settings, protection and gauging parameters" are required to be set before learning. All of the defaults I've found seem sane. I don't know enough about my batteries' limits to tune the settings much better than generic safe LiPo limits. Maybe I'm missing some configuration on this step that is a chip wide FET enable?

    4. I've attempted to follow your instructions and I cannot even get DSG FET output to turn on to start the first step of discharging the battery. I was able to enable the FET in the past so I'm very confident that my hardware setup is correct. My recollection is that bits 1:2 in Operation Status A (CHG and DSG) correspond to the actual FET outputs. I have not been able to switch those bits since the first time that I confirm I was able to. (Something must have changed. At a loss as to what might have.)

    In the hopes of figuring this out, I'm attempting to document exactly the steps that I've tried. I'm noticing inconsistent behavior after sending "RESET". Not all registers are reset to a known state.

    Cell, pack, and AC voltages detected:

    Initial Registers:

    After sending a RESET:

    After starting learn cycle:

    After sending FET_EN:

    After sending DSG_FET_TOGGLE:

    After sending CHG_FET_TOGGLE:

    After canceling Learn cycle:

    After Reset:

    After FET_EN:

    After Learn Start:

    After Learn Stop:

    After starting Learn again, which won't start because of RDIS bit:

    Repeat start Learn again, no RDIS error:

    At this point, I feel I've tried most combinations that make sense. Any insight would be greatly appreciated.

    Hello Cameron,

    I feel your frustration. Do you know the charging cut-off voltage, discharge cut-off voltage,  CCCV taper cut-off current and the capacity in mAh for your cells? These should be entered in the protections and Advanced Charge Algorithms portion of the Data Memory tab, if available. You can also start with the defaults. FET_EN should turn on FET_EN bit, but also CHG and DSG bits in Operation Status A register. I take it you're not getting any voltage across VSYS (J5) and PGND. It should be ~11.4V. Do you have a shunt installed on J7 for SYSPRES? If not install one and send a RESET command from bqStudio or go to Data Memory  tab in bqStudio >> Settings >> click DA Configuration >> set NR = 1 then send a RESET command. You should see the voltage on VSYS. This info is in the BQ40z60EVM user's guide in section 4.1. Let me know if this helped.

    Hello Damian,

    Thank you for the information. Unfortunately, this doesn't seem to work.

    We are using default values for " cut-off voltage, discharge cut-off voltage,  CCCV taper cut-off current and the capacity" from bq40Z60 for our cells. We have not tried to change those. The default values seem sane to me. The one value that seems like it might be weird is highlighted. But from my reading it looks correct. Please check these if you like:

    Setting the FET_EN bit via FET_EN command does not turn on the DSG and CHG bits as you suggest. This makes me think some hidden fault has been detected. However I haven't found any such faults.

    As is shown in the previous screenshots, PRES bit is set, indicating system is present as far as I can tell and outputs should be enabled. This is because we've set the NR bit.

    Maybe a factory reset command would work? I haven't been able to find such a command.

    Hi Cameron,

    Sorry, It shouldn't be this difficult. Can you send me a gg.csv file that you can export from Data Memory tab? I'm assuming you're not seeing VSYS output voltage on J5, right? Is the charger connected to the board when doing your checks? The charge (VAC) should be connected in order to wake up the gauge, else you will need to press the WAKE UP button S2 when using only battery.

    charge term voltage is ok at 75mV. It's how close to allow the charging voltage to get within the allowed max battery pack voltage. It's more like a guardband. If you import the srec file for the bq40z60, it will reset the flash to default. Remove the battery and charger. Let sit for 5 mins then reconnect the battery and charger. the device should back to factory default settings.

    Yes, I'm not seeing voltage on VSYS. I'm also observing the CHG and DSG outputs from the chip and that they stay at or below VBAT thus not turning on.

    VAC is connected. VAC voltage is detected by the bq40z60.

    Good call on the factory reset via firmware update. I will try that now.

    Edit: Forgot to attached .gg.csv (.txt to get around TI block)

    You are correct that the FUSE flag will prevent the FETs from turning on. The FUSE pin needs to be connected to VSS, if unused. Check to make sure that it is low.

    By "FUSE pin" do you mean the AFEFUSE pin? It is connected to ground via 105k ohm in my circuit. I see the EVM schematic uses ~25k. Is this enough of a difference to cause the FUSE bit to trip? This didn't seem to be an issue when this board was first assembled as I've previously been able to enable the FETs.

    Do you mean the AFEFUSE pin? Is that not an output? Why does its pull-down state matter?

  • 0 in reply to Cameron Tacklind
    TI__Guru 73830 points

    Yes, I was referring to the AFEFUSE pin. It is an bidirectional pin that can drive the fuse FET and also detect whether the 2nd level protector device has activated the fuse. It has to be connected to VSS, if unused.

    By " 2nd level protector device", do you mean the bq2947 that is recommended?

    I have a FET in my circuit to blow a PACK fuse that is connected similarly to the reference design with a 5k ohm fuse coming from each bq device. However for testing, I have disconnected the FET's output so the FUSE doesn't actually blow.

    I see now that the output of the bq2947 is at 3.5V. The AFEFUSE output is at 16.7V. The point driving the FUSE FET is at ~9V. This to me indicates that the AFEFUSE output on the bq40z60 is enabled. Does this correspond to the FUSE bit in Operation Status A? If so, why is the bq40z60 even tripping the fuse? Settings PF Fuse [A-D] are all 0 so my understanding is that it should not ever trip.

    I'm also confused by the "Min Blow Fuse Voltage". There are a couple related settings described in the reference manual but I can't figure out what the intention of this setting is and maybe this is causing the issues.
  • 0 in reply to Cameron Tacklind
    TI__Guru 73830 points
    Yes, that is the 2nd level protector device. Those are unusual voltage readings. I would not expect the bq2947xx to be 3.5V if the device is driving the output high or low. The AFEFUSE output should only drive up to about 7 or 8V. Can you attach your schematic, so that I can review it?

    The FUSE flag will set, if the device detects that the fuse has been activated to blow. Setting the PF FUSE bits and FUSE_EN = 0 will prevent the gauge from blowing the fuse.

    The "Min Blow Fuse Voltage" is the minimum value for Voltage() that will allow the gauge to try to blow the fuse. there may not be sufficient current to blow the heater in the fuse, if the voltage is lower than this threshold.

    Is it possible that something has damaged my bq40z60 (or bq2947)? Would that cause these issues?

    The only thing that is not captured in this schematic is the button functionality for waking.

    Q27 is installed but not connected to the FUSE.

  • 0 in reply to Cameron Tacklind
    TI__Guru 73830 points

    The circuit implementation for the fuse drive circuit looks correct, but I am concerned about the SN7002. I am not use that it can support the current required to blow the fuse. The FET may be damaged and causing the abnormal voltage readings that you reported. I would try removing the Q27 to see if the voltages return to their normal values. If you do find that the FET is damaged, then check to see how much current rating will be required to support the fuse heater. 

  • 0 in reply to ThomasCosby
    Intellectual 380 points

    While the SN7002 is installed in my circuit, it is not actually connected to the fuse currently. Therefore, I don't believe that could have caused the issue.

    I've removed R67 and connected R66 to ground. As in, OUT on bq2947 is floating, AFEFUSE has a 4.7k ohm path to ground.

    OUT is now at 0V.

    AFEFUSE is at VCHG-0.6V = 17V. I'm worried about shorting AFEFUSE to ground. Is this really necessary?

    Is it possible that the bq40z60 in my circuit is damaged? There is some minor evidence that the bq40z60 got a little hot at some point but I'd attributed it to soldering issues.

  • 0 in reply to Cameron Tacklind
    TI__Guru 73830 points

    The device may be damaged, bcecause the output should be low unless a PF is present. I would monitor the AFEFUSE with a scope, disable PF Faults (PF_EN) and send the PF Reset command. (29) See if the signal toggles low. it it does not go low, then the output is probably damaged.

  • 0 in reply to ThomasCosby
    Intellectual 380 points
    By "disable PF Faults (PF_EN)" do you mean send the "PF_EN" "command"? Sending that toggles the "PF_EN" bit in Manufacturing Status. Sending a "PF_CLEAR" command does not have any effect. This make me think we did somehow damage our bq40z60. I will be swapping the chip out soon and checking again.
  • 0 in reply to Cameron Tacklind

    I have replaced the bq40z60 on our circuit. Outputs turn on. It looks like our main issue was a faulty/failed chip.

    I'm still wondering what the full "Getting Started" procedure is. The reported current does not match what my supply and load readouts say. I'm guessing this is because I need to calibrate / input resistance values somewhere. I have not been able to find a guide that explains what is necessary to get accurate readings out. I'm sure that I will have more questions as I get into this.

    Hello Cameron,

    Glad you're making progress. To get accurate readings from the gauge  setup your gauge parameters for your application, run calibration using bqStudio (this will update based on your Rsense value) , ensure you have the best matched chemID for battery cells by using our GPC tool and run optimization/learning cycle with best match chemID. Note that as the gauge goes through several charge/discharge cycles of the battery (field learning) the accuracy will improved. 

    Most likely the readings you're getting is incorrect because the Rsense value is different. Check Data Memory>>Calibration>> CC gain and Capacity Gain. The default is 5mOhms. Calibration would help correct the value for accuracy or you can manually enter your Rsense value for a quick check. Calibration would be better.

    Are the DSG & CHG FET outputs supposed to stay on in REST?

    I've managed to get the learning cycle through the discharge stage and into rest. It seemed like the bq40z60 was turning off the DSG output automatically but it might have been the CUV kicking in.

    I'm hoping it does or that manually doing so is ok as I have a ~4mA load on my VSYS that I haven't tracked down yet.
  • 0 in reply to Cameron Tacklind
    TI__Mastermind 34665 points

    Hi Cameron,

    The DSG FET will be disabled during  discharge when a CUV occurs and the CHG FET will be disabled during charging when a COV occurs. Have you done calibration as yet?

  • 0 in reply to Damian Lewis
    Intellectual 380 points

    I have done the calibration but the calibration sets values incorrectly as far as I can tell. Please see this thread where I have described my current calibration woes. I am currently getting readings from the bq40z60 in bqStudio that agree with my meters.

    Are you wondering if the 4mA load is actually an offset calibration issue? It looks like a real load as my cells have lost about 1V over a couple hours.

    I'm worried that this load will affect the rest cycle significantly which is why I'd like DSG to disable. I also don't want to discharge the cells too low.

    Are you suggesting that I set CUV higher so that DSG does turn off and prevent further discharge?

  • 0 in reply to Cameron Tacklind
    TI__Mastermind 34665 points

    Hi Cameron,

    the 4mA current most likely will impact your rest/relaxation cycle, if it causes the dV/dt of the battery to be greater than 1uV/s. That's one criteria for OCV readings needed for Qmax update. I would recommend identifying that current source and resolving it. 

  • 0 in reply to Damian Lewis
    Intellectual 380 points

    I have tried to find the 4mA load. It seems to be drawn by the bq40z60 itself as I've disconnected everything else on VSYS and the load is still there. My dV/dt is around 37 uV/s. I'm considering trying to just send a FET_EN to disable the FETs during the relax cycle. Disabling the DSG fet stops the 4mA current draw. I will then re-enable the FETs at the end of the relax cycle.

    EDIT: Well, that didn't work. RDIS gets cleared and that kills the learning cycle.

    Hi Cameron,

    Are you getting valid charge termination and full discharge gauging flag settings when running your learning cycle?

    Hi Cameron,

    What is your Fuse blow FET connected to in your schematic? It doesn't seem to go anywhere. Please send me your GG and log file. I would like to look at your gauge settings and charging voltage. 

  • 0 in reply to Damian Lewis
    Intellectual 380 points

    Hello Damian,

    Yes, my fuse blow FET is not actually connected. We determined that we didn't require that feature, at least for now, but we wanted to at least have the part in the schematic. The FET is populated as shown. It just pulls a point that would otherwise be floating to ground.

    I do not have a full log yet as I still have not been able to run the learning cycle. Attached is the beginning of a cycle.

    I found the 4mA load. An extra resistor was installed that wasn't supposed to be. This created a 2k path to ground from VSYS.

    The latest confusion is that the AC Adapter Voltage is being reported at 10.5V while I can measure it to be ~16V at the ACP (31) and VCC (22) pins.

    I believe the discharge flags are set:

    Hello Cameron,

    Seems like your making progress. It may be slow and frustrating, but things are moving forward. The AC adapter Voltage  issue is strange. Maybe you have an incorrect calibration value. I would recommend redoing your calibration to see if it resolves the issue.

    I have re-done the calibration. There does not seem to be a way to calibrate the AC voltage. Manually adjusting the Voltage Gain settings, I can get the readings to change. I'd rather not guess and check to find the correct value...

    You can calibrate the Adapter voltage by turning the charger off and applying a voltage to the adapter input. Then use the Pack voltage calibration option on the Calibration screen in bqStudio.

    That worked perfectly. The documentation for calibrating the "Pack Voltage" has no mention of the AC voltage. This was a major source of confusion for me.

    The latest weirdness is that when I turn on the charger (CHARGER_EN), some load seems to be added to the ACP pin. The reported charger voltage drops to around 12V and this matches the voltage on pin 31, ACP. Adding to the confusion, ACLW is set when the device detects an AC voltage around 15V and ACLW is cleared when the voltage drops to the 12V.

    EDIT: When the device reports the lower 12V, I am still measuring 15V at VCC & the charge source does not report a load.


    Trying to run the learning cycle, it keeps getting interrupted because of the wrong state of QEN or RDIS: Error: [QEN: Not Set] [RUP_DIS / RDIS: Not Clear]

    The ACP pin powers the charge pump for the ACFET, so the voltage will drop across the 10k resistor. You can reduce that resistor to 1k to reduce the drop. I would increase the ACP voltage to prevent the ACLW fault. QEN should remain set unless you send the GAUGE_EN command. RDIS and VOK do not matter when running the optimization cycle.

    about schematic - why you put rezistors R45 (10kOhm) and R46 (10kOhm) between HSRP/HSRN signals and the shunt rezistor?

    they are missing at datasheet and EVM schematic..

    I was just checking the fuse circuit in the earlier posting and did not check component values. There are a lot of variants from our reference design and most of them will affect performance.

    • Check most of the resistor values in the charger circuit.
    • R45 and R46 should not be in the circuit.
    • R76 and R80 will probably need to be 0 ohm.
    • We do not recommend using a coulomb counter sense resistor smaller than 5 mohm.
    • C47 and  C48 need to be 10uF.
    • I am not sure how the 1N point on the battery stack connects to the sense resistor. There appears to be a resistor, R75, but it is grayed out. There should be a direct connection from the sense resistor to the cell.
    • What is the purpose of R82?
    • I am not sure where BAT-Pres goes. Pin 15 can be used for SYSPRES or ALERT. Pin 14 can be used for the LED button or EMSHUT button.

    Hi Cameron,

    To add to Toms comments.

    • R55 and R57 should be replaced with 0-ohm shunts
    • There are several different grounds and I'm not sure how they all connect. Our reference schematic uses a single ground
    • R77, R78, R81 and R83 should be ~10k

    Thank you all for the very useful information.

    Jury, good catch! I was copying the schematic from the low side sense. I will replace those with 0-ohm.

    Thomas,

    1. Working on it
    2. 0-ohm coming up
    3. On it.
    4. Ok. Somewhere I did some calculation that determined that 3mohm is what I needed. I will revisit this.
    5. Will this actually make much of a difference?
    6. My battery pack has 3 connectors. Two are the main high current connectors. One is for balancing. So you can think of R55 and R75 as 0-ohm resistors. More exactly, J4 is connected to the top of J5 and J6 is connected to the bottom of J5.
    7. R82 supplies BTN-Common which goes off to two buttons that can be used to wake the system. Either button will pull the "WAKE" signal to ground, which in turn connects the battery to the AC input to wake the device when on battery power.
    8. It seems I copied the signal names slightly wrong on my part model. BAT-Pres goes to a processor. It is currently left floating and we set the NR bit to compensate.

    Damian,

    1. See (6) above regarding R55. I thought I saw a 100ohm used for R57. Regardless, this shouldn't affect anything, correct? Currently R66 and R67 have been removed so the secondary protection device is effectively entirely disconnected.
    2. The ground connected to J6 goes nowhere else; It was more of a reminder for me during layout. The VSS ground is only used on this page of the design and is the ground just above the R79 sense shunt, but sensed as close to the cells as possible as it comes from J5. The ground that is connected to PGND is the ground to the entire rest of the system. This should match the GND and PGND from the EVM schematic.
    3. I was being lazy in my schematic and fixed it in the BOM. They are 10k ntc thermistors: NCP15XH103J03RC.

    Hello Damian,

    Your step by step instructions in this thread was very informative. However I have a few doubts in some steps. Could you please explain?

    "1. Discharge battery to 0% with C/5 to C/10 until Termination Voltage."

    Ques : Before discharging, should I enable the GAUGE ? What should be the status of RDIS bit and Update Status register during this stage?

    "4. Charge battery to 100% with C/2 to C/10 until taper is reached and valid charge termination is reached."

    Ques : Again what should be the status of RDIS bit during this stage ? Do I have to manually change anything before starting with this step or I can directly start charging after 30minutes of full discharge?

    "5. Wait 2hrs (R_DIS should be cleared during this relax time)"

    Ques : Do you mean to say that RDIS should be cleared manually or RDIS will be cleared ?

    And do I have to do all these steps through  Learning Cycle option? Or can I do these independently (ie without going into the Learning Cycle option)
