BQ40Z80匹配ChemID失败

使用1350mAh 6S1P LiPo电池匹配ChemID一直失败,参数设定如下,想上来问问是那儿出了问题


1.匹配ChemID需要0x21 GAUGE_EN = 1嘛,整个采集过程GAUGE_EN = 0

2.cell放电至3.2V休息2hr,再充电电压充至4V时就停止(不知何原因)

3.GPC报告出现有警告非零电流,在二次relax我是手动将FET_EN = 0 ,等时间到再将FET_EN = 1进行下一个步骤
是否这操作错误?

Warning: First OCVpoint has non-zero current I= -0.005 Please make sure you have a 2 hr relaxation period before the beginning of discharge.
