BQ24616充电问题3

Other Parts Discussed in Thread: BQ24616

各位大神,咨询个问题:

现在正在调试BQ24616,VIN=20V , 1-cell,Iadapter_limit=4A,Iprecharge=Iterm=0.2A,Icharge=1.5A,2-hour safety timer

在测试过程中发现接上电池之后状态灯一直在闪烁,根据状态灯判断系统在充电-充电完成-充电-充电完成之间循环,将Iprecharge更改为0.3A之后恢复正常,

但是当电压升高到4.02V之后又会出现之前的问题,我将电池充电线从原来的50cm改成10cm之后又恢复正常,这个是什么原因?

电池充电线的长度会对整个充电系统有这么大的影响吗?
