BQ34110: CEDV Profile parameters Question

Also, In the Excel configuration file, is the Minimum Voltage (cut-off) per Cell or for the entire pack ?

Hi,

More information on Fixed EDVx. 2.7.4 - bq34110 Technical Reference Manual (Rev. A) (ti.com) , values should be for entire pack.

More information on Voltage % DOD 2.7.10 - bq34110 Technical Reference Manual (Rev. A) (ti.com) , values should be for the entire pack.

These parameters are dependent on customer requirements.

Design voltage and design capacity for the entire pack.

Where did you get the excel linked?

config file should be formatted as stated here, 2.2.2 - Simple Guide to CEDV Data Collection for Gauging Parameter Calculator (GPC) (Rev. B)

Regards,

Evan

@evan, this is the configuration file, i just exported it. I multiplied by 4x Fixed EDVx, Voltage DOD and Design voltage.

Does the FD,FC,TD, TC section need to be for the entire pack too ?

Unfortunately, In the TRM it does not tell you if it is per cell or per pack ...

@evan, do you have a sample of the generated CEDV GPC report that I will obtain after i finish the calibration ?

I would like to see the parameters inside it for a multicell battery ...

The report  you joined do not show the DOD % values. 

I do not have VOC parameter , i have DOD.

Hi Evan,

Do you recommend in the CEDV Gauging configuration, to set the bit FIXED_EDV0 =1 (meaning i have to find the EDV0 myself) or should i disable it ?
