BQ40Z50r1电池学习过程中QMAX一直不更新是怎么回事？

Did you tweak the deadband or cc deadband? If yes, please change them back to defaults. For proper charge termination, I suggest that you let your current drop to about 80mA for at least 100 seconds before stopping current. The best way to charge terminate is to have the CHGFET option turned on in the registers. That way the charge fet will turn off on charge termination.
