BQ20Z655-R1: bq20z655-r1

Hello to Ti support team ,

     I have question according FCC ( Full charge capacity ) parameter .

 If I do cycles in my battery based on bq20z655-r1  based on conditions : stop  charge before 'FC' flag operates and discharge before 'FD' operates .  IS FCC will change ? or it is essential charge and discharge up to 'FC' and 'FD' to get proper estimated capacity  .

    Hi Alex

    The gauge needs reference points to maintain continuous accuracy. Full charge and empty are one of such reference points. While the gauge can still maintain a good amount of accuracy if they are not reached, overtime you will experience errors in DOD especially if you do not have relaxation period. That said, ensure to at minimum charge to full with FC flag getting set.

    thanks
