Hi expert,

My customer is evaluating BQ27Z746, there are some questions as below. Appreciate your reply.

How to configure the monitor range of battery cell voltage as 3.0V(Empty) to 3.7V(Full)?
How to do the Golden Learning when the monitor range of battery cell voltage is 3.0-3.7V?
How to do the CHEM ID when the monitor range of battery cell voltage is 3.0-3.7V? And could you provide the latest CHEM ID file and my customer can update the list.

Best Regards,

Ryker

Hello Ryker,

-The configuration of the monitor range is configurable in the BQStudio application in the "Register" tab. This tab needs the information in the image below that can be founded in the cell datasheet
Page 17:

-I think you are asking about how to do the Golden Imagine for a cell, and this is done though doing a learning cycle with the cell. Reference pages 15-19th in the mention document above.

-The ChemID is selected in the "Chemistry" tab in BQStudio, you have a list of already tested cell and the customer would need to would what P/N there cell is and find the correlating Chem ID

Regard,
Alan
