BQ27220: Which parameters Should I set before making Log files

Part Number: BQ27220
Other Parts Discussed in Thread: BQSTUDIO

Hi,

I am using bq27220 battery gauge in our project. I am trying to configure it with the help of EV2300 and BqStudio. In Data Memory of bqstudio it is showing three options

Calibration,Configuration,Gas Gauging

Calibration(OTP),Configuration(OTP),Gas Gauging(OTP)

Calibration(ROM Default),Configuration(ROM Default),Gas Gauging(ROM Default)

Can you please tell me that in which of these should I update the parameters so that I could generate log files and configure CEDV Coefficients.

Hi,

So you don't need to configure anything for generating the log files - you simply have to press the start log button to log the battery profile. As for obtaining the coefficients, you will need to submit your log files into the GPC Calculator and from there you file will obtain a file providing the coefficient parameters.

Take a look at this: www.ti.com/.../sluub45a.pdf

and http://www.ti.com/tool/gpccedv

Hope this helps,

Hi,

Thanks for your reply.

Since, I am using battery pack of 6 cells(3000mAh) connected in parallel(18000 mAh). So for that also do I need to change parameters or same will work
