18650B, 1C放电(20A),放一会SOC就跳0,FCC也跳0,放10%左右,0.2C充放电就没事,这个和曲线有关系吗?还是参数配置问题
Star Xu:
您好,您的CHEM ID是否配置,是否学习过。

之前学习的是2017

放电的时候 true Rem Q 会有一段数据异常,和跳变是同步的,,,20A放电SOC会跳0,15A放电SOC没有跳0,不过跳了几个百分点,这个数据异常的地方是什么原因导致的啊?一直没搞明白,15A数据异常的时间点会比20A长一些

Star Xu:
您好,方便将1C放电保护前后的画面截图发过来看一下吗?看一下是进入什么保护。
,
qingqing wang:
没有保护,只是电量跳0,还是可以继续放电,容量也够
静置数据
放电中数据
跳0后数据

您好,从放电中的画面上看XCHG的旗标举起了,请确认一下
