SLUUBT5C November 2018 – June 2021 BQ40Z80
Resistance updates take place only in DISCHARGE mode, while open circuit voltage (OCV) and QMax updates only take place in RELAX mode. If Fast Qmax is enabled, the Qmax also updates at the end of discharge given a minimum of 37% delta change of charge. Entry and exit of each mode is controlled by data flash parameters in the subclass Gas Gauging: Current Thresholds section. When the device is determined to be in RELAX mode and OCV is taken, the GaugingStatus()[REST] flag is set. In RELAX mode or DISCHARGE mode, the DSG flag in BatteryStatus() is set.
