BQ28Z610: 做了-40°低温补偿GPCRB

Part Number: BQ28Z610
Other Parts Discussed in Thread: GPCCHEM, GPCRB


  • 您好,请将GPCCHEM 报告,GPCRB报告和上传的数据发过来看一下。

  • 报告.zip这个报告请查收

  • 您好,请参考下面内容:

    It's probably going to be impossible to make this work well at -36deg.C (like in your log file). The gauge uses a model of both OCV and cell resistance and this model isn't covering extreme temperatures as accurately as necessary.

    At -36deg.C, voltage actually increases while the cell is discharged with a high rate (1C), even though temperature measurement isn't increasing significantly. The gauge model won't cover this behavior well.

    At the very least, the GPCRb input data must be created carefully, showing cell behavior at -36deg.C, which must include self heating while soaked (but not forced) in constant ambient temperature. It's critical that the thermal behavior from the gg_out.csv file is imported (together with the chemdat file).

    But even then, it's likely not going to work well at -36deg.C.

  • 你好,这个跳变幅度太大了,从86%到0%,能不能减小这种幅度控制在20%内都能接受,或者寄电池给TI实验室测试ID,能否达到更好的效果

  • 您好,没有找到其他方法减小幅度控制。如果需要寄电池建议您联系sales或者FAE,我这里无法查到没有联系。
