BQ2060在做Learning时,放完电后再对电池进行充电,Relative State of Charge:0%,Absolute State of Charge:0%,Remaining Capacity:0mAh,全部都是0,但Sense Resistor inputs Current采样的电流值都正常,在进入恒压充电阶段后,充电电流小于Current taper threshold设定值时,突然:Relative State of Charge:100%,Absolute State of Charge:100%,Remaining Capacity:(full charge capacity) mAh全部都调整.在这种情况下Cycle count也不准确,只做了一个Cycle,但显示出来的可能会在几十个Cycle.不理解是什么原因,请各位高手指教!!!500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/61/58771201313895.jpg?x-oss-process=image/watermark,g_center,image_YXJ0aWNsZS9wdWJsaWMvd2F0ZXJtYXJrLnBuZz94LW9zcy1wcm9jZXNzPWltYWdlL3Jlc2l6ZSxQXzQwCg,t_20');}" onmousewheel="return imgzoom(this);">

问题解决了没?突变成100%和你的fastchargetermination的设置有关,当电流到达tapcurrent时,RM会突变到fastchargetermination的值的.至于在恒流阶段为何没有变化,我也觉得挺奇怪的.你可以把2060取下再焊上,来一次硬件复位,看看怎么样?
实然变100%和我的Current Taper Threshold设有关,这是因为充电电流小于于设定值,问题是为什么前段不记容量,还有Cycle count数值会突变.我将EEPROM设定介面传上来看一下.
