你好,我们有用两种电芯在R5固件基础上做电池包的电量学习,学习后(update status=0e)都有注意到其中两个寄存器的状态位和R2的学习后的状态位不一样:LStaus中CF1:CF0以前R2学习完后是0:0,用R5学习后为1:0.请问是什么原因导致不能变成0:0?
Star Xu:
您好,正常学习成功是10,00是初始状态。
,
xiaojuan xiao:
请问初始状态是什么状态?CF1:CF0的状态解释是:00=battery ok;10=qmax and resistance updated in learning cycle;
想请教的是LStatus下的CF1:CF0状态位,不是update status下的update1:update0
,
xiaojuan xiao:
之前R2学习后这两位读到的是00。现在R5学习后读到的是10

您好,正在询问更了解这款芯片的TI工程师,稍后回复。

你好 请问有相关答复吗?
,
Star Xu:
您好,请参考下面内容:
Both firmware version (R2 and R5) have the same definitions and operation of the CF0, CF1 flags.
Please provide the BQStudio logs showing the difference. The only thing changed is the BQZ file with the R5 firmware, the LStatus register display was changed in BQStudio, operation in gauge firmware is the same.

AL-2162-20230822–.gg.csv这边有用两种电芯,在4串、3串上用R5固件做过学习,学完后也是CF1为1,附件为学习后的gg文件,请帮忙分析,谢谢!
,
Star Xu:
您好,方便将学习的log数据发一下吗,
,
xiaojuan xiao:
是学习时持续log的数据?这个没有。学完后log瞬间的数据可以?或者学完后的SREC文件可以吗?SREC文件太大,这里上传不了
,
Star Xu:
您好,SREC文件打包成压缩文件上传可以吗
,
xiaojuan xiao:
AL20230617.zip请查看,谢谢

Star Xu:
您好,正在查看,稍后回复

Star Xu:
您好,Please provide the BQStudio log showing the behavior you mention, the .gg file shows the update status and it is showing normal for a fully learned gauge.

xiaojuan xiao:
What does the BQStudio log exactly mean? Can you get information from the SREC file which was sent before?
