BQ34Z100-G1: 多次循环后FCC偏小

Part Number: BQ34Z100-G1
Other Parts Discussed in Thread: GPCRB

4串最低容量为14.5Ah的电池包学习成功后按照0.5C进行充放电循环;

多次循环后查看Log数据,发现有以下问题:

1、Cell Terminate Voltage设置为3000mV,但是RSOCRM总是在12.4V左右为0,而不是在12.0V

2、使能RMFCC功能,但在充满静置2h过程中RM逐渐减小,该怎样调整配置使其在放电时才开始降低?

3、最后2个循环的FCC突然偏小,由14190mAh跳变至8919mAh;

附件为bq34z100-g1的gg文件、Log数据以及化学ID,麻烦分析下原因,谢谢!B0859-ID2349-study-2023-12-18.gg.csvB0859-ID2349-0.5C-2023-12-14 .csvroomtemp_rel_dis_rel-report-2023-11-2.zip
