Part Number: BQ34Z100-R2
Other Parts Discussed in Thread: GPCCHEM

Tool/software:

Hello :We are going to use HAKADI Sodium Ion battery for a development job.

How do we get GPCCHEM for that and how do you use it M what is its importance?

Are specific controllers available from TI ; in place of the Chinese CM1901AN?

What should we pay most attention to? Why cannot BQ family be programmed?

What if our stack of SIB is 380V and we want to charge that stack?

thnx

appreciate any help.

-Use the GPCCHEM calculator to verified that there isn't already a chemID that has less than a 3% in DoD difference, and if there is not that a new ChemID would need to be made for that cell. For that please contact your local Field Application Engineer from TI to began the process.

-BQ34z100 should be able to handle the battery gauging aspects of the cells
