BQ34Z100-G1: 电量计电池学习遇到的问题

2023-04-27 分类：电源管理 阅读(220)

Part Number:BQ34Z100-G1Other Parts Discussed in Thread:BQ40Z50,

以下是我配置电量计芯片和电池学习过程

  1. 根据实际项目规格配置DF参数，选择正确的CHAM ID烧入；
  2. 对板子进行校正；
  3. 导出这个时候的senc/srec文件备用；
  4. 连接电芯到板子，发送reset命令，得到Golden Pack；
  5. 把电池放空到3.0V，然后静置5个小时；
  6. 发送命令使能IT算法；
  7. 把电池充到饱，确保有效的充电中止（100%,FC置位），然后停止充电；
  8. 静置两个小时；
  9. 把电池以C/5放空到终止电压，然后停止放电；
  10. 静置5个小时，检查update status和Ra flag；
  11. 重复7~10步骤一次。对于bq34Z100-G1：当update status的数值为0x06，Ra flag是0x0055时，说明学习成功。对于bq40z50平台芯片，update status为0x0E为学习成功；
  12. 导出gg文件，手动修改cycle count=0, lifetime, manufacture status=8000等。对于bq34Z100-G1，修改update status=02；
  13. 烧入第3步备份的senc/srec文件；
  14. 导入第12步修改好的文件，得到golden sample；
  15. 生成量产文件，比如senc/srec文件或者DFI文件。

我是第6步出现问题，正常情况下，[VOK]=1，但是我的[VOK]=0，且学习过程中也没有置位。其他标志位正常。

 

以下是我的电量计配置参数。

Star Xu：

您好，VOK 在某些电压范围内长时间放松可能会清除该位。您的CHEM ID 报告，gg文件和log数据发过来看一下。
