Hello community,
is there any possibility to balance my batterypack (with bq76940 and bq78350) after finishing the charging proceedure?
I use a LiFePo4 Pack and balancing is just really happening at the last minutes of charging because the charge curve of this batterytype has big flat part in the middle. For that part of curve the adc accuracy is not high anough for good balancing. I suspect that balancing only at the end of charging is to less for lifepo4 cells. My batterypack has 12 cells 20Ah.
In bq78350 datasheet is written: "Since cell balancing is typically only performed during pack charge or idle periods..."
Can I use the idle mode to do this? How it works?
Thanks a lot
Armin
