BQ34Z100EVM: How to configure BQ34Z100EVM for a 36V; 10000 mAh;360000 mWh; 10S4P battery

We do have an R2 version of the IC. Can we change the BQ34Z100 IC on the EVM to the R2 version inorder to make it work for the above requirement? 

Hello Sethu,

R2 firmware version will be available for download tomorrow.

Just out of curiosity, replaced the BQ34Z100 IC in the EVM to BQ34Z100-R2. Made the same configurations (no. of series cells: 100; design energy scale: 100; design energy: 3600). Now even the voltage value being read is not right. 

Made a voltage calibration after making all the configurations,
Instead of  42000mV, the value shown is 4200mV.

And all other parameters such as SOC, Available energy, etc are zero now. (IT has been enabled).


Morover, the BQSTUDIO software (Stable version and Beta Version) donot include BQ34Z100, BQ34Z100-R2 to choose. It only shows BQ34Z100-G1 in the list of devices selectable. 




So I am forced to select only BQ34Z100-G1. Then the following screen pops up.




Queries:

1. Is the BQSTUDIO software not 100% compatible for BQ34Z100-R2?

2. Is that the reason why, most of the parameters are zero and the voltage is scaled differently?

3. What should be done to update the BQSTUDIO to support BQ34Z100-R2 and read all the parameteres properly?

The issue with the BQSTUDIO and BQ34Z100-R2 compatibility is solved. Thank you Steven Yao

But there are new parameters in the data flash but the Design Procedure in the Datasheet not seems to be updated as per that.

For example, the previous discussion was about Energy scaling, the R2 device does not even have the Design Energy  parameter only has Design Energy Scale.
Its really hard to find, what to refer, what to do, where to start. A suggesstion to TI would be to update all the procedures involved in the development cycle of a product in the document. 

Hi @Steven Yao,

I am referring to the same document,



The above snippet from the datasheet of R2 says to update the Design Energy in the DF. 

But the Data Flash does not even have such a parameter.

    This parameter has been changed to hidden, needs to create a new bqz file for your to access this data, I would work with internal team and send this to you once it is done

Hello Sethu,

It may be a week before you get a reply from Steven

Thanks for the update Steven Yao Shirish.

I am ok to wait for a week. Appreciate the support of both of you. 

We started development over 2 months ago (with all the versions non-G1, G1, R2). Had to read multiple versions of same document(s) to get an idea of how one IC/ product works. Due to a lot of documentation issues, we are not able to achieve our goals faster. I would like to suggest TI, to streamline the documentation, especially the design process. Thanks. Hoping to hear from you, soon.

    Seems that the new bqz is still not available, you can send me your configuration file with all other parameters set, I will change Design Energy parameter for you

Thanks for the support. We are proceeding with G1 version for now.
