您好,请参考TRM 4.6 Valid Charge Termination

为什么超过了0.25mAh且其他条件也满足没有100%? 然后0.25mAh在gg文件里怎么体现?
,
Star Xu:
您好,确认一下GAUGE_EN是否使能。
,
wen mai:
您好,GAUGE_EN没有使能,Mininmum Taper,值为750都不受影响,为什么改为800,后面就不能100%
,
Star Xu:
您好,我在TRM 上没有找到minimum taper charge的参数介绍,正在查询,稍后回复。
,
Star Xu:
您好,minimum taper charge不建议修改,建议使用默认值。
详细请参考下面的内容。
This parameter is normally a private one. Which version of bqStudio and FW are you using? This parameter should be left default, and is not used in the way you think it is, instead it is used for charge accumulation during the taper window. There is no way you will accumulate 800mA in 40 seconds.
The parameter you want to configure correctly is the "Taper Current". Normally this value is in the C/20 range.
