BQ27421-G1: Sudden jump in SoC

Raquel Alejandra Ramirez Valencia

Part Number: BQ27421-G1
Other Parts Discussed in Thread: BQSTUDIO, EV2400, GPCCHEM,

Tool/software:

Hi,

We're using the bq27421 gas gauge, and the host micro is responsible for configuring the design capacity, design energy, terminate voltage, and taper rate. After setting these, we issue an exit_resim. We're reporting the battery % every 30s approximately. The SoC increased gradually from 15% to 98%, but then suddenly dropped to 79%, and after that it climbed gradually back up to 86% and was maintaned there.

We're trying to understand the reason behind this sudden drop from 98% to 79%. Is this behavior expected due to the Impedance Track algorithm adjustments, or could it be due to a misconfiguration on our side?

Also, just to confirm, the parameters (design capacity, design energy, etc.), must be configured again if the device (that contains gas gauge) is turned off correct?

Any insights would be appreciated. Thanks!

Hello Raquel,

Can you send a log file of this behavior occurring? Can you also send the gg file from the gauge.

Regards,

Adrian

Hi Adrian,

Sure, here is the log where we report the battery %. Regarding the gg file, could you please tell me how can I extract that file?. Also, just to clarify, I'm not using the bq evaluation software, the gas gauge is already embedded on a device.

Thank you,

Raquel.

Hello Raquel,

Can battery voltage, current, temperature, full charge capacity, remaining capacity, and SOC be shown in the log file. Tracking these parameters during the duration of the test is vital for me to debug the issue.

Regards,

Adrian

Hi Adrian,

Ok, I'll create a log file with all of those parameters. Thank you.

Hi Alan,

Here is the log with the parameters. SOC decreased from 99% to 79%. gas_gauge.log

Hello Raquel,

Would it be possible to connect the board to an EV2400 and run the State of Charge (SOC) decrease from 99% to 79% and have it recorded as a .log file within BQStudio, this would allow viewing all the possible parameters within the gauge. It is most likely that there is a setup issue and If the battery datasheet and .gg file are attached, the setup can be reviewed and suggestions can be offered.

Thank you,
Alan

Hi Alan,

Thank you for your response. Right now it's not possible for us to use the EV2400 board. I understand that would be the best way to debug the behavior, but I wanted to check if there is an alternative to review if it's a setup issue.

Hello Raquel,

You could blue wire and tap into the I2C bus, GND and input those lines into the EV2400 to read from the gauge itself then log your event. In the meantime I can give some basics suggestion for your .gg file based on what your cell datasheet says. Also some basic sanity question for your setup, did you use the GPCCHEM tool to find your best fit pre-programmed chemID, if so can you attach the report? Were your available to run a calibration cycle?

Thank you,
Alan

Hi Alan,
We don't program the chem id. The model is bq27421, which indicates in the datasheet that unlike some other Impedance Track fuel gauges, the bq27421-G1 cannot be programmed with specific
battery chemistry profiles.

We use the commands (sent via I2C) to setup the design capacity, design energy, terminate voltage, and taper rate.

Hello Raquel,

When you use the GPCCHEM tool it should be able to tell you out of the three possible chemID configuration for this product which chemID best lines up for your battery. Also I understand that you use I2C commands to setup the gauge but can we see those configuration through a .gg file along with the cell datasheet.

Thank you,

We don't use the bqstudio, however, I was able to verify through the commands that we have the chem id G1D.

I've attached the parameters used to configure the gas gauge (we don't have a .gg file), and the information about the battery.

Hello Raquel,

We can take this discussion offline through the private message to share the .pdf file for the datasheet and the complete list of data memory values. Also could you showcase the gpcchem report that lead your team to pick the G1D chemID version to verify if the pre-program gauges are a correct pick for your cell.

Thank you,
Alan
