BQ40Z50-R1: How temperature protection recovers

BQ40Z50-R1: How to enable Temperature protection in fuel gauge

Part Number: BQ40Z50-R1
Other Parts Discussed in Thread: BQ40Z50, BQSTUDIO, BQ40Z50-R2

Hi All,

I am trying to enable over temperature and under temperature protection on BQ40Z50 fuel gauge. I tried to write temperature value into cell temperature hopping that setting high value for temperature will over automatically enable the protection by reducing charging or discharging current or by disabling the pass FEs. I was able to manually write high temperature values to FG by writing to Sbs_Configuration and set SMB-CELL_TEMP bit to 1. I was able to see the change in BQStudio as well. but there was any protection mechanism enabled by this high temperature. While reading through the reference manual it was understood that there are some registers i need to set and some other operations are needed. I need help in understanding this. Below are my queries.

1) What are the operations i need to do in fuel gauge to enable temperature protection.

2) What are the protections that i can enable in the fuel gauge related to temperature.

3) How does this protection mechanism works.

It will be great if i could get this questions answered. 

Thanks,

PG

    Hello PG,

    The TRM has a good description of how protections work. See Chapter 2 https://www.ti.com/lit/ug/sluubc1d/sluubc1d.pdf

    Section 2.8 deals with temperature. The selection of thermistors needs to be configured. DA configuration needs to be updated. I don't think cell temperature can be written on bq40z50 as it seems to be marked as a read only register.

    Hi,

    It is mentioned that the write_temp is a write only register and it is 16 bit. The resolution is .1 K. I can see this working as well. Also when i read getting  "0x08 Temperature()" register,  I am able to read back the value i am writing to write_temp register. In my use case i am disabling thermistors  by writing to Sbs_Configuration and set SMB-CELL_TEMP bit to 1. Below image i am writing 50 deg C and it is reflecting in BQstudio.

    Have one more doubt, is the cell temperature used as an input to temperature protection, because for the current project I am working on i wont be relaying on NTC as temperature data source, but we will write temperature values to cell temperature and see the effect of temperature on the system.

    Hello Priyan,

    The protection section does not reference host written temperature configuration, therefore it is possible that it is not a valid configuration for protection to  get triggered. I will assign this thread to Wyatt since he helped you with the write_temp earlier.

    Hello Priyan,

    Can you share the .gg file for your gauge configuration as well as a BQStudio log of the test you are trying to do? If you do not have the protections enabled then even if you set the temperature high nothing will happen.

    Sincerely,

    Wyatt Keller

    Hi Keller,

    I have not enabled the protection feature. I am trying to understand how and what i need to do to enable this. Basic input will help me start with the enabling process. I have gone through the user manual and it was bit hard for me to understand. Can you give me a basic brief of what i need to do to enable the protection, while charging and discharging. I will share the log and .gg file tomorrow.

    Thanks.

    Hello Priyan,

    You should be able to set all the protection in BQStudio under data memory->settings there is a section for protections and PF.

    Hi Keller,

    I have few more follow up questions related to this. Our use of fuel gauge is different compred to conventional battery. We are using this fuelguage to develop a battery simulator where we can change temperature and voltage to mimic real battery sinarios. As such we are using write_temp command to directly write the cell temperature without using sensors. Following are my questions.

    1) Using only Cell temperature data, can we enable temperature protection.

    2) Can we use the cell temperature for over and under temperature FET protection, over and under temperature protection for charging and discharging and so on.

    3) What are all the temperature protection i can enable by writing cell temperature if all are not possible.

    Thanks,

    PG

    Hello Priyan,

    I would not recommend setting up a battery simulator for the gauge, the algorithm is quite complex and you will probably run into multiple issues depending on what type of tests you plan to run. The best way to run gauge testing is with a real battery and a battery cycler like Arbin or Maccor along with a temperature chamber.

    You should be able to configure the USER_TS so that it is set for the Cell Temperature and should trigger protections.

    Sincerely,

    Hi Keller,

    In the current design we have implemented, the board doesn't have NTC on it. The host is sending the temperature value to the FG and it is written to the cell temp register through write_temp command. This is working as we are able to see the change in BQStudio. We would like to know following.

    1) In this method too will we be able enable enable temperature protection?

    2) If possible, which are the registers we need to enable. Current code we are increasing the temperature above 200deg C and we are not seeing any protection kicking in.

    3) What are the expected behavior during under/over temperature situations with respect to the settings we need to enable in FG registers.

    4) "You should be able to configure the USER_TS so that it is set for the Cell Temperature and should trigger protections.". Is this USER_TS any register in FG because we are not able to locate this in user manual.

    Thank and regards,

    Priyan George

    Hello Priyan,

    let me look into this further, I need to check with the firmware team if the temperature supplied by user can be used for protections.

    sincerely,

    Hi Keller,

    Please check and update the same so that we can have this implemented in our design. As per the understanding from user manual, it has to support I believe. Awaiting your confirmation.

    Thanks,

    Hello Priyan,

    Waiting for their feedback now.

    Hello Priyan,

    Feedback was that the firmware uses the user input for the temperature just like the ADC input that the gauge would normally measure. So you must configure the settings to trip.

    Sincerely,

    Hi Keller,

    Just to clear my doubt, is there any specific register we have to configure to enable the protection if we implement in this method.

    Or  can you give me the list of registers that i have to configure to get this working. Currently we are not able to  see any change in behavior when we write high temperature to the FG although the temperature value is set correctly and we are able to read back the same in BQstudio.

    Thanks and regards,

    Priyan George

    Hello Priyan,

    Yes all the conditions outlined in the TRM for the temperature protections. For example, UTD all of these condition must be met:

    You must also make sure the actual protection is enabled in the Settings section of data memory, it should be enabled by default.

    Sincerely,

    Hi Keller,

    Following are the settings done for temperature the FG.

    Following are the protection enabled.

    Following image captures the cell temperature and the mosfet states. it is observed that at 99deg C both the mosfets are still on even though my temperature settings are well below this temperature. This is same in case of charging and discharging.

    Are we missing anything here. Please help.

    Thanks and regards,

    Priyan George

    Hello Priyan,

    The FETs are still on because you are in the FET test mode and have manually turned them on. The gauge will not control the FETs when you have FET_EN = 0. FET_EN must be set to 1 for the gauge to control the FET action.

    Also you must have the correct TempEn set. Please share your .gg file and log of tests.

    Sincerely,

    Hi Keller,

    As i was unable to attach the .gg file, pasting it here for your reference.

    Hello Priyan,

    I am also having trouble changing the value under certain conditions, I think there might be a check in the FW for large jumps in temperature. Try changing the values slowly as I look into this more, see if it helps.

    Sincerely,

    Wyatt Keller

    Hi Keller,

    Sure let me check by changing the temperature gradually. Also can you check if there is any miss match in settings in .gg file.

    Thanks,

    Priyan George

    Hello Priyan,

    I believe the root of the issue is because the value is filtered, so you will need to write to the register multiplied times before the filtered value settles.

    Sincerely,

    Hi Keller,

    Which value are we talking about here. Is it the temperature value or is it some other register value?

    Thanks and regards,

    Priyan George

    Hello Priyan,

    The user temperature sent to the gauge by the host. The input is filtered so you cannot write the temperature once and have the value trigger a protection because, for example, UTD protection uses the min of the cell temperatures and it is filtered. In normal operation the temperature will essentially be updated once per second.

    Sincerely,

    Hi Keller,

    As you said we have enabled FET-EN to high and have increased temperature from 80 to 100 deg cel in steps of 1 in every 1 sec and we also tried it in steps of 1 in every 2 sec. Still Both FETS are not turning off. Can you let us know if any other reason is causing this or we have to check in any other way.

    Thanks,

    Priyan george

    Hello Priyan,

    I will take a closer look at this today.

    Sincerely,

    Hello Priyan,

    Sorry for the delay, I did not have enough time yesterday. I'm checking with our SQM team if they have validation data from this firmware feature. According to the FW team this should essentially replace the temperature read by the gauge TS so it should work with both settings for USER_TS.

    Sincerely,

    Wyatt Keller

    Hello Priyan,

    Wyatt is out of office today, he will reply when he gets back.

    Hello Priyan,

    After digging through the code and asking around further it looks like you are testing with -R3 code, which does not apply the WriteTemp() value to protections, it is only used in the in the charge control temperature values. You must update your firmware to version -R4 in order to have the protections be enabled with USER_TS settings. This also requires a override key so it cannot be written erroneously.

    The two firmware versions (R3 and R4) implement this feature differently.

    Sincerely,

    Wyatt Keller
