你好：
请问一下BQ27426 在learning cycle进不了 charge mode是哪里的原因？
Cherry Zhou：
您好我们已收到您的问题并升级到英文论坛，如有答复将尽快回复您。谢谢！
,
Cherry Zhou：
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。
,
qiuping chen：
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？
,
qiuping chen：
你好，这是相关的GG,CSV文件bq27426.gg.csv

Cherry Zhou：
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。
,
qiuping chen：
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？

Cherry Zhou：
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。
,
qiuping chen：
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？
,
qiuping chen：
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
,
qiuping chen：
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？
,
qiuping chen：
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
