Other Parts Discussed in Thread: BQSTUDIO
Hi, Team
I have finished the bq35100's calibration and get a average gg table.
But my customer still have some questions :
"It is very unclear to me which changes to the default values you are making and why. I need more details from you to understand this.
please explain why the change is required from the default value from the TI Data Flash Table 13-1 ."
And my answer is that:
"Some of value rounding off due to the number of significant figures .
All of the Calibration Data in the GG Table which are the responsibility of factory is auto changed by doing Calibration process with TI bqstudio software.
Pack V Offset :
For calibrate the V Offset between the value read from Gauge IC and Actually voltage.
CC Offset:
For calibrate the Coulomb Counter Offset when turn it off all except the gauge IC , Current read from gauge ic should be 0 in this condition.
Board Offset:
For calibrate the Offset affected from board
CC Gain and CC Delta:
For calibrate the Current of the battery by measuring the voltage drop across a small-value sense resistor between the SRP and SRN pins
Temperature:
For calibrate the temperature between value read from gauge ic and actually temperature.Because we use a external temperature sensor , the bit 7 of Reg Operation Config A need set to 1, so the Operation Config A changed to 0x84.
"
But it doesn't satisfy customer's requirements.
My customer want to know:
