3.2测量精度

GC1388的A / D转换单元是12位的电压和温度感测，最多18个比特用于电流检测。

3.3容量计算

GC- QC- 388累积电荷的量度和放电电流，并估计了自放电这个包。

它可以补偿温度和自放电的电流测量和调整的RM到准确的容量。

3.4 FCC自我再学习

在整个有效放电过程中，它积累能力的变化并获得新的FCC 。

新的FCC = FCC最初+ DCR （放电到EDV2 ） + FCC * 6 ％

6％的容量百分比在小区的EDV2 。

一个FCC再学习过程：

1.从完全充电

2.放电达到EDV2

3.在这个过程中没有有效充电

4.自放电小于250mah

5.无过放电电流发生在这个过程中

。

6.温度不低于4℃

3.5应关注的差异在FCC

当计算与实际容量之间的差得到的设定值时，该模块将通知主机

执行FCC再学习的过程。
