BQ27546-G1: Designing with bq27546-G1 and charger IC

Part Number: BQ27546-G1

Hi Team,

A bq27546-G1 is used in a customer board. the device resides on the system’s main board with a nonremovable battery, How should a charging circuit be connected to the bq27546-G1? Do charging chips need path management? Please see image below.

I looked at the EVM as a reference but I am confused as the Cell +/- (battery) and Pack+/- (charger) seem to be connected. is my understanding correct? 

Is there any other reference design that shows bq27546-G1 being connected to a charger IC? 

Thanks!

Regards,

Marvin
