BQ40Z50R1电池容量学习失败，已经得出ID值和Ra值，但是数据导入进去充放电容量还是不准

Other Parts Discussed in Thread: BQSTUDIO

问题如标题，请TI各位大神帮忙指点

1.电池型号：SAMAUNG INR21700-50E

2.电池组： 3串28并，最大放电电流200A

3.我是使用单节电芯做的充放电数据采集，把数据曲线上传到TI网上，同时TI有回复出来相对应的ID，但是给出的ID值在BQstudio chemistry都是相同的，完全和我使用的电芯规格不符。

4.使用给出的电芯ID值继续操作GPC Golden GG Maker整理资料上传TI,TI回复给出对应Ra值，把给出的Ra值数据导入BQstudi，电池组进行充放电测试容量还是不准

我的问题是：

1.电池化学ID是学习单节还是这个电池组3串28P？

2.如果要TI工程师帮忙测试得到电芯定制ID要如何操作？

3.按我自己的操作采集的ID值和Ra值，请帮忙阅读下我上传的附件资料，看看哪里操作不对，不知道附近有没上产成功。

2337.第一步获取电芯Chem ID.rar4578.第二步获取电池包Ra值.zip

    计算ID是用电池组跑充电数据

    计算得到的ID就是接近您的电芯的ID

    我用电池组跑充电数据计算ID值，上传文件内的电压是以总电压为准还是单节cell，电芯节数是否要改成 NumCellSeries=3，如下信息请帮忙确认下。谢谢！

    ProcessingType=2
    NumCellSeries=3
    ElapsedTimeColumn=0
    VoltageColumn=1
    CurrentColumn=2
    TemperatureColumn=3

    NumCellSeries=3，voltage是总电压

    你好，我是你的建议采集电池组数据，上传TI网站给出ID值误差太大，附件是我采集的数据和TI回复的结果。请帮忙看看数组资料是否有哪里有问题。谢谢！
