Zusammenfassung:	The invention discloses application of a synchronous rectification DC/DC converter. The application comprises that the synchronous rectification DC/DC converter is connected between input and output interfaces of a large-power charging device; during charging, step-down, freewheeling, boosting and rectification MOS tubes of the synchronous rectification DC/DC converter are controlled, so that thesynchronous rectification DC/DC converter works in a voltage transformation state and charges a battery pack which is connected to the output interface; and during discharging, the step-down, freewheeling, boosting and rectification MOS tubes of the synchronous rectification DC/DC converter are controlled, so that the synchronous rectification DC/DC converter works in an electronic load state anddischarges the battery pack which is connected to the output interface. Thus, the cost of the large-power charging device can be reduced, the heat radiation effect can be improved, and current-constant, voltage-constant and po
