I try to do a golden file with bq20z65-r1 and battery from A123 ANR26650m1B.
I follow all application report without success:
When I do learning cycle, I enable IT and Update Status change to 04.
I charge the battery at C/2. When the charge is done, I have FC enable in Battery Status.
After 2 hour or more of relaxing, Update Status stay to 04 and Max Error to 100%
I had tried the same design with a different battery (US18650VTC3) with success.
I have an old design with ANR26650m1B but I hadn't problem to do the golden file.
For ANR26650m1B, you have 2 ID for the chemistry: 0440 and 0453, for my old design I used 0440, what's the difference?
Thank you for your help.
