    As in pg4 of d/s, there are three LEDs output in for bq2031 to give the status

    The IC can tell the Charging status,  you can consider Battery full when in Maintenance charging, Battery low when in Pre-charge,

    For Battery in use, we need external comparator to sense the discharge current for judge it.
