Title:
Battery Fuel Measurement Using Delta-Sigma ADC Devices
Name:
AN1156

Description:
The battery fuel status indicator is a common feature of the battery-supported handheld devices. The battery fuel measurement is achieved by measuring the discharging and charging currents in real time. The discharging current is the current coming out from the battery and the charging current is the current flowing into the battery. The fuel used (mAH) and the fuel remaining (mAH) are calculated by tracking the discharging and charging currents over time. The fuel used is the total discharged current over time and the remaining fuel is simply the subtraction of the fuel used from the fully charged fuel.
