BQ4050 MaxError跳动问题

Other Parts Discussed in Thread: BQ4050

各位TI的专家与大神们:

        我的电池主板使用的是BQ4050电源管理芯片,学习成功后MaxError为2%(learned fcc =5100),但是用着用着到后面出现了MaxError到了11%(learned fcc =32763),这个是怎么回事呢?是哪里的参数引起了他的变化呢?急等。

       感谢感谢!~

  • maxerror

    Max error is incremented internally by 0.05% for every increment of CylceCount after the last QMAX update. MaxError is incremented in the display by 1% for each increment of CycleCount.

    Event                                           MaxError

    Setting Full reset                         Set to 100%

    QMAX and Ra table update        Set to 1%

    QMAX update                              Set to 3%

    Ra table update                           Set to 5%
