BQ76940EVM: fet problem

Part Number: BQ76940EVM

hi;

thanks for your reply.I have another question about fets.

as you see in pic; the fets combined each other like dual connection ı think it is suppose  to increasing the capacity of carrying current.But when charging begins they are not working at the same time.I removed one of them then the second one was on . how they work together at the same time ?

additionally;The charge current must be 15A or smaller according to referance design but when charge begins the current limited around 6A .Could it be related to the condition of the fet sutiation?Or should it change  the sense resistor ?

Thanks in advance .

.
