大家好，

以下是客户提出的问题，可能需要您的帮助：

问题：在学习周期中，它无法进入充电模式。您能否帮助您了解原因是什么？谢谢。

您好，Cherry，

根据此图，客户似乎已将蓄电池放电，但学习周期工具仍希望确保其放电，然后再继续下一步。他们能否施加负载，使其达到端接电压以推动流程？放松后，应切换至CHG模式。他们是否已经这样做了，但却被卡住了？如果是这样，最好有一个日志文件和.gg来了解原因。

谢谢！

您好，Cherry，

除了Alex提到的内容之外：

DSG电流阈值和Chg电流阈值是仪表用于切换模式的参数。如果他们没有检测到模式更改，则很可能没有为其应用程序正确配置这些设置。切换模式还会延迟Chg Relax Time (Chg放松时间)和DSG Relax Time (DSG放松时间)。

从图像上看，它似乎正在检测模式更改。

此致，

Alex和Wyatt您好，

感谢你的帮助。

Chg驰豫时间和DSG驰豫时间默认设置为60秒，DSG电流阈值和Chg电流阈值是大于退出电流阈值的电流值。如何配置？

下面是.gg文件：

您好，Cherry，

您的充电电流阈值似乎设置为约150mA，因此您需要在超过150mA的情况下充电60秒才能进入充电模式。日志看起来不是实际充电，应捕获整个周期的日志，以便我们可以查看模式转换。

此致，

它们的电荷电流有多大意义？

从校准开始导出日志信息，还是在无法进入充电模式之前不导出日志信息？

您好，Cherry，

我不理解主要问题是什么，他们是否尝试进行校准并遇到问题？或者他们是否尝试执行学习循环，仪表将不会切换模式？

校准应在学习周期之前完成，以便我们获得准确的测量结果。我们不需要校准日志。

我们需要查看的日志是当他们从Relax开始充电，然后停止充电以查看我们是否正在更改模式时，但第一步是校准。

此致，

Wyatt Keller

您好，Wyatt：

谢谢，请让我澄清一下：

主要问题是在执行学习周期时，无法进入充电模式。

以上上传的日志在解除后。硬件侧有1.6 A为蓄电池充电。但是，BQSTUDIO电池学习界面不显示充电界面。您可以帮您检查一下吗？

谢谢，此致，

您好，Cherry，

查看之前共享的日志，我可以在标志寄存器中看到DSG位已清除，因此仪表正在进入充电模式。实际上，它在CHG模式下的停留时间比发送的第一个日志要长。

他们是否只是在寻找bqStudio无法识别CHG状态的原因？因为仪表看起来像是处于CHG模式。

此致，

您好，Wyatt：

我402.6217万我可以在报价寄存器中看到DSG位已清除，因此仪表正在进入充电模式。[/]
意味着DSG位被清除，表示仪表已进入充电模式？只有 bqStudio 能够识别CHG状态？那么如何进行操作呢？

谢谢，此致，

您好，Cherry，

我只是想确认他们所需的操作及其相关内容，以便我可以向团队中更了解bqStudio的其他人推荐。

现在，仪表似乎正在进入充电模式。您能否共享完整的充电和放电周期，以便我们可以看到模式转换？

此致，

您好，Wyatt：

电池培训周期成功后，需要导出哪些文件？

您好，Cherry，

GM.FS可导出并用于在学习后将所学信息和配置上传到新仪表。
