BQ35100: Getting correct SOH from chip in EOS mode

Part Number: BQ35100

Our target is to use the BQ35100 for monitoring EOS of an EVE26500 battery.

There is a chem-id profile already available for this and we have programmed that one correctly.

 

We have followed the technical ref manual, chapter 5.3  to set the chip in correct mode.

 

Still following the manual for collecting data during our drain of current, we are still not able to get a SOH reading that differs from zero.

Our assumption is that a fresh battery should show 100%.

 

So, bottom-line is that we are not able to see any working progress of the chip.
