My application requires prevention of using aged/degraded battery pack (or battery pack with same chemistry but lower capacity). The purpose is to ensure there is enough battery capacity to sustain for whole operation whenever a battery pack is inserted to my system.
Example, my system suppose to use battery pack with 2200 mAh capacity (2 parallel cells pack). I have a golden profile of 2200mAh programmed into bq27510. So subsequently in my application is it possible for bq27510 to do a detection whenever a degraded battery pack (eg. capacity degraded to 1760) is inserted and this information is updated to my system? Or certain learning cycle has to be made for this to happen? If yes, what are the conditions to enable updating of the degraded capacity information to happen?
I have tried using battery pack with reduced battery cell to single cell (1100 mAh). It seems that bq27510 was unable to reflect the reduction of capacity. It still shows the full charge capacity to be about 2200 mAh.
Please help. Thanks.
