Can some one help me with the following questions:
- How critical OCV (Open Circuit Voltage) to be measured accurately; i.e. suppose that after coming from Shutdown, the load is not zero (not really OCV condition), what would that cause? Will the impact of inaccurate OCV measurement get lesser and lesser over time (smoothed out in the algorithm)?
- On the state diagram (showed in the data sheet the Technical Reference) we see SLEEP mode and system shutdown (which contains WAIT_HIBRENATE and HIREBNATE). However, when I look at the commands or subcommands, I see SET_HIBERNATE and CLEAR_HIBERNATE as well as SHUTDOWN_ENABLE and SHUTDOWN; but none for SLEEP. Why? Is it because SLEEP is entered automatically and we cannot just get into this mode with a command?
- As we know this device has some algorithm that uses the measured battery voltage to estimate the SoC with measuring the current. One could think with such algorithm, there are chances of incorrect estimation. Is there a mechanism that detect anomalous estimation, like at how smooth the time-series is for the estimated SoC? If so, is there a flag to tell us that there is a question mark on the estimation?
- On the state diagram, it shows HIBERNATE mode could be entered if Vcell < Hibernate Voltage, while in the HIBERNATE Mode section, it talks about current and not voltage. In that section also, it does not mention that this mode is entered from SLEEP.
