BQ27Z746EVM-047: 无法正常给电芯充放电

您好，

我想用评估板给电芯做Golden Learning。

在未使能MOS管时，在充放电测试模式下，可以通过BQ27Z746评估板给电芯正常充放电，但无法正常Golden Learning。

发送FET_EN指令，使能MOS管后，会直接触发XCHG和XDSG标志位，无法继续给电芯充放电。

按压唤醒开关时，PACK+与PACK-之间会短暂获得与BAT+、BAT-（电芯两端）相同的电压，一旦松掉开关，又会重新没有电压。

也就是只要使能了FET，无论是否按压唤醒开关，都无法充放电。

电芯用的是samsung 18650 25R。

疑问：这种情况是触发了电量计的保护功能还是充放电管周边电路已经损坏？如果是触发保护的话，如何解除？

谢谢！

    您好，看到您的电压2.7V左右，是不是这个原因造成XCHG和XDSG，您将cell电压恢复到正常值再reset试一下。

    Hi, Star.

    电芯充满电之后，使能FET，依旧触发XCHG和XDSG，如图1、2变化。

     

    另外给按照图3 Golden Learning步骤给电芯充电，第一步没有问题，

    但是第二步满电的时候满充Flag FC始终没有置位，

    此时充电电流已经小于设置的充电截止电流了，如图4所示

    图1

    图2

    图3

    图4

    您好，请确认是不是进入CTOS保护。请参考TRM 4.3.11 Fast Charge Timeout Protection

    Hi, Star.

    未触发CTOS保护的时候，只要使能FET，就会触发XCHG和XDSG，无法充放电。

    您好，能将这个过程的log数据发过来看一下吗？
