PRODUCTION DATA
The calibration of current, voltage, and temperature readings is accessible by writing 0xF081 or 0xF082 to ManufacturerAccess(). A detailed procedure is included in the BQ27Z561-R1 Technical Reference Manual (SLUUBY5) in the Calibration section. The description allows for calibration of cell voltage measurement offset, battery voltage, current calibration, coulomb counter offset, PCB offset, CC gain/capacity gain, and temperature measurement for both internal and external sensors.
