3.4.1 Coulomb Counting in Battery Using Accumulate Mode
To estimate the charging level when the battery charges, its charging current should be measured and accumulated. In the case of a battery discharge stage, for measurement of the battery state of charge (percent capacity remaining), the battery discharge current should be measured and accumulated as a coulomb counter. When combining the coulomb count and the estimated battery charge, an estimate of the battery health is calculated. ADCC with Accumulate mode can be used for the same. The timer (auto-conversion trigger feature of the ADCC) may trigger the ADC conversion of the battery current to provide a consistent sample rate.
