BQ34Z100-G1: Calibration failed

This means that the voltage divider value can't be set correctly for the divider configuration (VOLTSEL and external circuit) that you use. 

See TRM www.ti.com/.../sluuco5a.pdf, 3.4 for information how to select a compatible external divider (and make sure that VOLTSEL is correct).

Hi

The attachment contains a GG file and SCH, pack configuration = 4161。

calibration still cannot be completed。

What's the actual voltage that you measure at the input to the gauge (with a volt meter)?

Hi

The actual voltage is 3679mV
The voltage measured by the gauge is 3673mV

That's the voltage that the gauge reports in your screenshot. I am interested in the actual voltage that you measure on the voltage input pin to the gauge.

That voltage must be within the range specified in the TRM. This is accomplished with a proper voltage divider. The gauge then needs to know the voltage divider value. This is within certain limits and the calibration routine may not be able to calculate this within the limits and then you get this error message.
