I''m looking at designing a protection circuit for a li-ion pack and noticed a lot of secondary protection ICs (e.g. BQ2947) offer delays between detection of OV conditions and triggering of the fuse. Why would this be a useful feature? My best guess would be to allow time for data logging in smart battery packs before the battery is shut off.

This method can provide secondary protection for lithium-ion batteries used in high-voltage equipment at a relatively low cost since the circuit has a simple configuration without using any special components.
Battery protection unit The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on. BMS IC
According to statistics, about 85% of the batteries are fired and exploded because of the battery. The problem of the core itself, therefore, the protection of the battery from the protection circuit is limited. Summary . As the energy density of lithium battery cells continues to increase, safety will be more valued.
