BQ40Z50: Ra value is not updating and Update Status not changing to 06 on its own...

Part Number: BQ40Z50


Hello TI,

Learning cycle was done and Update Status changed to 05 but after that its not changing to 06 after doing discharging at c/5 REST bit was set after complete discharge. Why is my Update Status not setting? I waited for it but still no success. So, I decided to start charging it.

So, I started charging the cell again (single cell configuration) BUT my SOC stopped updating. AT this time my Max Error is 3% and cycle count also did not update (as this is the new cycle, I think my learning cycle failed as update status remained 05.. It should be 06 according to TRM) What to do now ? Please help. Right now my SOC is shown as 8% at 3820 mV which is surely wrong. Before it was updating quite well. Why SOC is not updating ?

Also why my update status did not change ?
