    您好，根据您给的图片来看，已经将电池放电了，但learning cycle tool仍需要确保在进行下一步之前电池放电。 您试下施加负载使其达到端接电压。放松后，请切换到 CHG 模式。

    您是否已经尝试过以上步骤，但是卡住了？如果是的话，那么还需要您提供下 log file和.GG。

    此外，DSG 电流阈值和 Chg 电流阈值是电量计用于切换模式的参数。 如果未检测到模式更改，您很可能没有为您的应用正确配置这些参数。 在开关模式下、还会有一个 Chg 放松时间和 DSG 放松时间的延迟。

    您给出的图片看起来是在检测模式变化。

    你好， Chg 放松时间和 DSG 放松时间都是按照界面显示的默认值60S，DSG 电流阈值和 Chg 电流阈值都是大于e quit current threshold的电流值，那应该怎么设置？

    您好，您的充电电流阈值似乎设置为大约 150mA ，因此需要在 60 秒内以超过 150mA 的电流充电才能进入充电模式。 log看起来不是实际充电的，最好能够提供整个周期的log，以便我们可以看到模式转换。

    您好，

    1：您说60秒以内超过150电流，那我的充电电流要多大才合理？

    2：整个的LOG是指从开始校准的时候就开始导出LOG信息还是直到进不了充电模式才导出LOG信息？

    您好，您主要的问题是什么？我们目前不太清楚这一点。是在进行校准时遇到问题？还是在尝试执行学习周期时，电量计不会切换模式？

    校准应在执行学习周期之前完成，以便获得准确的测量结果。 不用校准日志，我们需要的日志是：从relax开始充电，然后停止充电时，可以看下是否正在改变模式，但第一步是校准。

    你好：一直稳定问题是进不了充电模式？反反复复都是问这个问题，进不了充电模式哪里有充电的日志？

    尝试执行学习周期时，电量计进不了充电模式，有电话联系吗，这样效率比较低，这个问题搞了比较久还没解决

    一直问的都是学习循环的时候进不了充电模式，什么时候问校准了？为什么进不了充电？

    还有你仔细看了没，上面给的是校准日志？麻烦帮仔细看看，进不了充电 模式这个问题搞好久了，你们都没帮解决

    您好抱歉哈，目前该问题我们还是求助英文论坛工程师的，以上链接是帮您升级到英文论坛的帖子，您先看下。新的答复我会再帮您反馈到工程师这边，如果您比较紧急的话，您可以试下直接与工程师沟通，或者您多多关注下工程师这边的回复。为您带来的不便敬请谅解！

    你好，上面上传的LOG就是放完电之后，硬件端是实实在在有1.6安培的电流充电给电池，但BQSTUDIO电池学习训练界面没显示进入到充电的界面

    你好，帮忙催一下贵司工程师看看是哪里的问题，谢谢

    您好，您之前给出的log中，在标志寄存器中， DSG 位被清除，因此电量计是正在进入充电模式的。 实际上，在 CHG 模式下的时间比在您发送的第一个log中的时间长。 因为已经进入了充电模式，目前的问题是bqStudio 无法识别 CHG 状态？ 因为电量计目前处于 CHG 模式。

    你好，您的意思是DSG位被清零是进入充电模式？bqStudio 才能识别 CHG 状态？

    你好那要怎么操作？

    您好，工程师这边想跟您确认下，您希望的操作是什么以及与什么相关？这样我们再求助更了解bqStudio 的同事。 仪表目前正在进入充电模式。 您是否可以分享完整的充电和放电周期，以便我们可以看到模式转换？

    一直在问怎么在电池学习训练的时候怎么进入充电模式，怎么你说我希望什么什么操作？怎么分享完整的充放电周期？莫名其妙发现你问的问题，不是已经把相关LOG给你了么？还没发现是哪里的问题？有仔细看过没？除了那几个电流阈值和时间还有哪里会引起进不了充电模式，或者说 DSG位要怎么设置才能进入充电模式？有没有电话沟通，感觉论坛上一个问题问的是什么，你们反反复复问。

    成功的进行了一个电池训练循环之后要导出哪些文件，是发给你们帮弄出来电池曲线吗？

    您好，可以导出gm.fs，它是用于在学习后将学习到的信息和配置上传到新的仪表的。
