BQ34Z100-G1: 制作量产文件时,导入学习成功的gg文件后,是否需要write all,写入芯片。

Part Number: BQ34Z100-G1
Other Parts Discussed in Thread: BQSTUDIO,

学习成功后,成功导出GG文件,并修改好update state 02以及cycle置 0. 制作量产文件时,导入预学习时候的SREC,到这一步是OK的,然后导入前面学习成功并修改好的GG文件,导入后data memory列表的数据是有

变化的。到了这里,我是否需要点击IMPORT 右边的Write_All,然后再导出量产的SREC。1、我试过没有点击WRITE ALL,只是导入gg然后导出量产的SREC,然后烧录量产的SREC,Ra的表格是不正确的。所以觉得是

要点击WRITE ALL,才能导出量产的SREC。2、我点击write all的时候,出现写不进去的情况。提示是CC DELTA超出了范围。看了规格书以及配置,这个是在校准的时候,芯片自动修改的,不需要用户修改。但是提示了

超出范围,然后就写不进去,最终也导出不了量产的SREC。  请帮忙解答以及协助协助解决一下。谢谢。

  • 您好,请参考下面内容:

    I would like to share how I resolve the problem with CC Gain and CC Delta. According to BQ34Z100-G1 data sheet CC Gain could be from 0.1mOhms to 40mOhms.  The smaller value that I could enter in bqStudio's CC Gain field is 0.125mOhms. If I try 0.1mOhms bqStudio doesn't accept it. What I did is to use the bqStudio's Calibration Window, I ran discharge current of about 20A then I calibrated the gauge saying that current is -20,000mA, switch back to Data window and read what the gauge wrote in CC Gain. If it is higher than 0.1mOhms, then switch back to Calibration Window and enter a smaller current, let say -19,000mA, calibrate again and read back CC Gain from Data window until the gauge write 0.1mOhms.  During the calibration BQ34Z100-G1 properly adjust CC Delta field.

  • 我这个是用2mR的,这个电流在学习的时候已经校准了的。现在是导出量产文件的时候,我导入学习好的gg文件,导进去导不进去,写进去的话,就会提示CCdelta超出了范围。ccDELTA这个值,不应该超出范围的。

  • 您好,固件是不是用的最新版? 您可以试一下烧录SREC文件,CC Delta是否修改成功。
