For details on how the BQ35100 device operates, see the Battery and System Health Monitoring of Battery-Powered Smart Flow Meters Reference Design Guide of the TIDA-01546. For the tests with electronic load and NB-IoT modules, a special reference file (also called ChemID) for the FDK CR17500EP battery is generated by TI, which allows accurate SOH measurement of this battery.
Only one of the two power devices in the TIDA-010053 is powering the NB-IoT module (or electronic load to start with) from the FDK battery at a given time, as described in Section 3.1.4.
