BQ40Z50_R1 Qmax不更新

A QMax update is disqualified under the following
conditions:
Temperature — If Temperature is outside of the range 10°C to 40°C.
Delta Capacity — If the capacity change between suitable battery rest periods is less than 37%.
Voltage — If CellVoltage4..1 is inside a flat voltage region. (See the Support of Multiple Li-Ion
Chemistries with Impedance Track Gas Gauges Application Report (SLUA372) for the voltage
ranges of other chemistries.) This flat region is different with different chemistry. The
GaugingStatus[OCVFR] flag indicates if the cell voltage is inside this flat region.
Offset Error — If offset error accumulated during time passed from previous OCV reading exceeds 1% of
Design Capacity, update is disqualified. Offset error current is calculated as CC Deadband / sense
resistor value.
