BQ28Z620: Register Description

Part Number: BQ28Z620

What is the difference between BAT voltage and battery (0x08)?

I only found a few descriptions in the specification book. Please help explain in detail the difference between the two and related operations during calibration.

    Hey Fabio,

    Voltage() is the sum of each individual measured cell voltage. While, Bat Direct Voltage is essential the voltage read at the top of stack. Calibration is essential will be updating both of these values. Calibration will force the top of stack voltage to a certain voltage (the voltage used in calibration).
