    Simple Guide to Chemical ID Selection Tool (GPC)

    The Gauging Parameter Calculator (GPC) Golden GG Maker is a math calculation tool that helps the battery designer to select the best chemical ID for a given battery to use with Impedance Track gauges.. The battery pack must use one of TI’s Impedance Track algorithm-based fuel gauges. It requires a log file of a charge / relaxation / discharge /relaxation test that can be created with various test equipment such as Maccor or Arbin battery testers or by using TI’s Battery Management Studio (bqStudio) software with an evaluation board connected through USB.

  • CHEM-ID的计算是用整颗电池(4并10串)充放电记录数据,还是用单颗电芯充放电记录数据

  • 只需要单颗电芯的放电数据即可

  • 最好是4并1串去测

  • 我是记录整个电池包的放电数据,计算出的CHEM-ID误差超出了3%,学习后发现senc文件对电量计算不准,充电结束静止期间电量一直在下降,见附件。

    此外我对配置文件里的参数Design Capacity 和Design Energy 不是特别理解。我是10串4并的电池,单颗电芯容量为2150mAh,标称电压为3.6V,满充电压为4.2V,我是这样配置的,不知道对不对,请指教。

         Design Capacity =2150*4=8600mAh

         Design Energy=Design Capacity*36=309600
