BQ78350-R1: Cycle count jumps to more than 2000

Hi Martin,

This is really strange. Is this showing on the same device where you reported the other incorrect readings?

Hi Matt,

yes it is the same.

Hi Martin,

Okay, let's continue to debug on the other thread. I think the two issues are likely related. I'll close this thread for now.

One different thing is, that the cycle count stays at the new value and even when I read it with BQStudio it has this value

Hi Martin,

Which program did you get the above images?
Did you calculate the graph, "calculated SOC" value and "PDB SOC" values ​​on the state of charge section?

Thanks A lot...

Hi Umit,

I plotted them my self from our logs. Yes calculated SOC and PDB SOC are our own estimations.

How can you calculate SOC value? Is there any TI reference document?  Is there any relationship between temperature and SOH values ​​when calculating your soc value?

No we just evaluated remaining capacity to total capacity
