我目前有一个BQ40Z50,用在3串电池上面。学习成功了,最后一步到电到12V,Cell 1–4 Chg Voltage at EoC 都在4V左右,且电量百分比为100%, 7242.pdf

应该是你的参数配置问题导致电量计在12V充电时也认为满足了充满的条件。
你的Charge Term Voltage设成多少?还有Advanced Charge Algorithm里的几个charging voltage是多少?
Charge Term Voltage 250mV; Charge Term Taper Current 200mA,Advanced Charge Algorithm里的几个charging voltage是4.2V.附件为GG文件3162.gg.zip
