Tool/software:
Question 1
Internal cell balancing
1. Datasheet(pg6)
2. Datasheet(pg14)
3.
Battery used(Vcell):4.2V max
Formula:
Internal cell balancing current= Vcell/Rcb =4.2/ 48(shown at 2.)= 87.5mA
Therefore, 4.2V/42ohm=100mA. 42ohm is the minimum resistor value in order to obtain 100mA. My calculation is it correct?
Question 2
I wish to add extra mosfet in red circle and green circle to parallel CHG mosfet and DSG mosfet to reduce current flow though each mosfet as I am using 30A. But my concern is there also a mosfet for precharge and predischarge in the circuit which already reduce the inrush current. Is there any conflict to add it or ...?
