Other Parts Discussed in Thread: BQSTUDIO, , EV2400
Hello,
My company previously used the EV2300 with the bq27530 v1.04 software to write a .gg file on to the bq27530-G1. We are now transitioning to using the EV2400 and bqstudio to complete this process. I found that the .gg file I used for the bq27530 v1.04 software is not compatible with bqstudio; bqstudio requires a .gg.csv file with a different delimiter format.
To get a new .gg.csv file in the correct format, I used the export function in bqstudio to export the parameters from a bq27530-G1 already configured with my original .gg file. This worked well, however I have a few questions about the CC Gain, CC Delta and CC Offset values.
1) I noticed that I get a slightly different CC Gain value (21.649 mA on the EV2300 and 21.653 on the EV2400) when I read the Calibration values from the same bq27530-G1/battery combination but using the EV2300 with bq27530 v1.04 software and the EV2400 with bqstudio. Do you think this is because of the difference in EV2300/2400 hardware?
2) I see that the CC Offset value does not update to whatever is value is set in my .gg.csv file. For instance, if the value in my .gg.csv file is -1400 and the value when I read all cal values is -1200, it will stay -1200 after I write the values from the .gg.csv file. Is this because the CC Offset value calibrated directly from the gauge itself, so the value in the .gg.csv for CC Offset is not written to the gauge when I "write all" from the .gg.csv?
3) Similar to my question about the CC Offset, are CC Gain and CC Delta actually written on to the bq27530-G1 from the .gg.csv file, or are these values in the .gg.csv "ignored" when written on to the gauge, since the gauge performs its own calibration to get these values?
Thank you very much for your prompt response. Please reach out if you need any more details or follow-up in order to answer my questions.
