Part Number: BQ40Z80
Other Parts Discussed in Thread: 4430, BQ40Z50,

Hi,

There is abnormal operation in charging and discharging.

cell is 6 series 2 parallel and 3400mAh.

Designed capacity is 6800mAh

charge1: charge.csv

FCC is quite different from designed capacity.

Even though long time charging, full charging flag is not set.

Discharge: discharge.csv

remaining capacity goes to 0 from 2807mAh suddenly and FCC is updated from 4301 to 1495.

With continuous discharging, FCC is updated up to 3794.

charge2: charge_1.csv

charging is stopped periodically. CHGC and CTOS is triggered during this operation.
