Abstract

PURPOSE: A charging station capable of controlling a charging capacity and rapid charging process of electric vehicles is provided to reduce facility investment costs by sharing one mass storage PFC(Power Factor Correction). CONSTITUTION: A noise filter part(2) reduces noise of a switching power supply part. A PFC(Power Factor Correction) control part(3) maintains a power factor of an AC power source to 98 percent or greater. The PFC control part supplies a stable power source to DC/DC charging parts(5,6,7,8). A large size charging port(11) is connected to the DC/DC charging part. The large size charging port is comprised of an electronic switch which is opened and closed according to an ON/OFF control signal. A general charging connector(14) performs a charging function of a general electric vehicle. An integrated control part(17) monitors an operation situation of all DC/DC battery chargers. A signal connection part(18) is used as a communication line transferring a communications signal of the PFC control part and DC/DC charging part.
