BQ40Z50: CELL BALANCING

Part Number: BQ40Z50

Hello!

I am trying to understand the method of cell balancing at charge state.

on page number 5 of SLUSCB3  there is a scheme of bypass fets which are capable of 10 mA balance current.

my question is how does the controller manage to balance the cells for example if the charging current is 1A but the balance current is only 10 mA (at charging mode balance)? 

if the answer is no . is there any design example for adding an external balancing fets or circuit in order to balance the cells?

thank you very much.


Victor.
