产品概述
描述
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.
