BQ27425-G2A: StateOfHealth - How does status change

Part Number: BQ27425-G2A

Section 8.5.1.13 of datasheet lists the various possible SOH status (0x21).

Any details on what are the requirements to trigger the different SOH status? For example, for 0x03, is the trigger that the QMAX_UP flag is set?

    Hello Eddie,

    The SOH updates at similar times as the FCC, for Ra and Qmax updates the SOH will also update since these directly impact SOH. When a Qmax occurs the SOH status should also update to 0x03 after an SOH simulation is run which should be at the time of the update.

    Sincerely,
