PRODUCTION DATA
When a battery pack enabled with the BQ27Z558 gas gauge is cycled, the value of FullChargeCapacity() updates several times, including the onset of charge or discharge, charge termination, temperature delta, resistance updates during discharge, and relaxation. Figure 8-3 shows actual battery voltage, load current, and FullChargeCapacity() when some of those updates occur during a single application cycle.
Update points from the plot include:
