BQ27426: 使用软件进行Learning Cycle时出现VOK标志位错误。

user6458813

Part Number: BQ27426

您好，我使用Battery Management Studio软件对bq27426芯片进行参数训练，每当充电完成然后静置的这段期间，软件都会因为VOK标志位错误直接退出训练。以下是我的训练设置的参数，请问下哪里设置有问题还是你们的软件有问题？

错误的信息为：

Fri Sep 24 08:50:02 CST 2021: Learning cycle started...
Fri Sep 24 08:50:02 CST 2021: Start task: Discharge ( TerminateVoltage = 2900 mV )

文档 bq27426 Technical Reference中对VOK标志位的描述是当Qmax更新正确的时候就会自动设置

VOK = Indicates cell voltages are ok for Qmax updates. True when set.

但是之前我问过你们https://e2echina.ti.com/support/power-management/f/power-management-forum/209197/bq27426-battery-management-studio-bq27426

你们说这个Qmax标志位是自动更新的，那我就更不解了。上图是我对软件的一些设置，CHEM_ID我使用了TI默认的1202的配置，请问如何解决？

您好，是否方便提供gg文件和learning的log 数据。
