Description
Fuel gauge technology is a smart system which
monitors battery capacity, predicting the
remaining capacity and displaying its status. The
basic unit of measurement used for battery
capacity is Coulomb counting, in which the
current flowing through the battery is continuously
monitored and integrated to calculate the
capacity.
Current measurement is done when the battery is
both discharging and charging. Therefore, both
the IN and OUT current are used to calculate the
remaining capacity of the battery.
Battery capacity is measured in mAh.
