电源管理芯片参数At Rate和 State Time异常

Other Parts Discussed in Thread: BQ28Z610

1.根据datasheet, At Rate是一个符号量,可正可负。负值代表放电值,当它为零时会同时把 AtRateTimeTo Empty 置位成65,535。但是你从下图可以看到 At Rate的值是29439mA,那么是不是意味着产品曾经以29.439A的电流充电或者短路过?

2. State Time means Time past since last state change (Discharge, Charge, Rest)

下图State time是76837s, 但是实际上我们几乎所有产品这项值都小于200s?是什么原因会导致这项值异常呢?
