BQ27220: GPCCEDV got error.

Hi Jerry,

No i do not. Our algortithm lead was able to get a valid result with your file, see his response below:

I  analysed this case and tried to run with many different min and mas SOC range settings.

What I  founds is that there is nothing wrong with the data, but they are difficult to fit and will have higher error

because:

1) wider temperature range, from 60 to -15C (accuracy will always be lower in wider temp range).

2) high voltage chemistry starting with 4.3V, having different shape close to end of discharge

My best result is attached, still not great but much better then what they had.

I used min and max settings of 3 and 8, and a new chemistry file made

for high voltage Li-ion (chemistry type 8).

It is already supported by the tool, but we need to add it to the manual.

The report is attached.
