A MULTI-FUNCTIONAL ELECTRIC VEHICLE CHARGING DEVICE FOR DC DISTRIBUTION NETWORKS USING HIGH CAPACITY DC/DC CONVERTER

摘要

PURPOSE: A multi-functional charging device for an electric vehicle for a DC distribution network using a high capacity DC/DC converter is provided to reduce an installation space for a charging device by using a plurality of charging connectors which is drawn from a single high capacity DC/DC converter. CONSTITUTION: A voltage control part(110) measures electric energy provided to a charging device and the electric energy consumed in the charging device. An integrated management control part(120) calculates charges and charges. A DC-DC converter(130) changes high voltage DC power for an electric railroad vehicle into a low voltage DC power. A BMS(Battery Management System)(140) collects battery information from an electric vehicle. An output unit(150) outputs the electric energy in the charging device and charging information for each charging connector.
