Title:
VEHICLE HAVING POWER SYNCHRONIZATION METHOD USING ONE-CORD POWER PLUG
Document Type and Number:
WIPO Patent Application WO/2023/048324
Kind Code:
A1
Abstract:
A vehicle of the present invention comprises a battery and an energy storage system, which is mounted on the vehicle to charge the battery with power, provides power for charging a load outside of the vehicle, and synchronizes power discharged in order to charge the load with commercial alternating current power supplied through a receptacle outside of the vehicle if a one-cord power plug is connected to the receptacle in order to charge the load, wherein the energy storage system comprises: an alternating current/direct current conversion unit; a battery; a voltage boosting unit; a direct current/alternating current conversion unit; a power control unit; an inductor (L) connected to a supply terminal (ACP) through which commercial alternating current power (Vac) is supplied; a switching unit (SW) having one terminal connected to the inductor (L) and having another terminal connected to an input and output terminal (IOP); a current determination unit for comparing an inductor current (IL) with a power recovery limit current (Iref); and a switching control unit for turning on the switching unit (SW) if the inductor current (IL) is lower than the power recovery limit current (Iref), turning off the switching unit (SW) if the inductor current (IL) is the same as the power recovery limit current (Iref), and turning on the switching unit (SW) by enabling a switching control signal (SWC) if a reference time (Tref) elapses after the switching control signal (SWC) is disabled.
