BQ40Z50-R1: Cell Balancing at Rest(CBR)

user4576477

Part Number: BQ40Z50-R1

Dear all,

I think the "Cell balancing at Rest" is a good function for series battery, but I found the setting CBR default is 0, what's symptom need to care? SOC decrease after cell balancing or etc....?

Hi user4576477,

To enable cell balancing at rest, please assert CBR by setting Balancing Configuration [CBR] = 1. The gas gauge balances the cells by balancing the difference in SOC between the cells.

Cell balancing at rest can be configured by determining and setting the following parameters in dataflash:
Min Start Balance Delta
Relax Balance Interval
Min RSOC for Balancing

For more information, please see section 14.4.12 of the TRM: www.ti.com/.../sluubc1c.pdf

Sincerely,
Bryan Kahler
