In Document SLUUAH7B (Quickstart Guide for bq27421-G1), Section 4, paragraph related to TERMINATE VOLTAGE, the text states that the TERMINATE VOLTAGE is the target where the gauge 'typically' reports 0% capacity.
What are the other factors that affect the reporting of 0% capacity? The text of the referenced document notes that the gauge 'learns the level of load spikes' , but does not supply any information of how those are learned or used. Does the passed charge factor in at all to the 0% reporting condition? How about ambient or Cell temperature?
We are seeing inconsistent use-times between charge/discharge cycles and wonder if the gauge is indicating 0% capacity when the actual State of Charge condition of the battery may allow continued operation.
I appreciate that the algorithm may be proprietary but as much information that you can provide would be useful.
