Abstract:
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.

Abstract:
PURPOSE: An induction power collecting apparatus for a high capacity electric vehicle for reducing core loss and an induction power feeding system are provided to compensate a reduction in a magnetic flux inter-linkage amount while using a low frequency by reducing leakage magnetic flux in a magnetic flux inter-linkage surface of an induction power feeding body, thereby supplying low frequency power to the induction power feeding system or induction power collecting apparatus. CONSTITUTION: An induction power feeding part(10) includes an induction power feeding body(11) and is installed on a line. The induction power feeding body is coiled by a power feeding line in order to compensate an amount of mutual inductance attenuation according to a frequency reduction when a power source is replaced to a low frequency power source from a high frequency power source. An induction power collecting body generates electromotive force corresponding to the mutual inductance of the induction power feeding body. A power collecting part(20) comprises the induction power collecting body. The induction power collecting body or induction power feeding body are manufactured with amorphous or nano-crystalline core.

PURPOSE: A wheel type ultrahigh-speed train system is provided to simplify a switching system, compared to an existing magnetic levitation train, using a standard train wheel type system. CONSTITUTION: Wheels which is installed to the truck(210) of a vehicle(200) is contacted with rails which are formed on a train-road. A supporting stand(104) is installed between the rails. A repulsive linear synchronous motor(LSM)(120) is installed between the truck and the supporting stand. The repulsive LSM improves driving performance by reducing the axle load in a high speed region. First and second steel plates(132, 142) are slantly installed on both sides of the supporting stand. First and second attractive motion-controlling magnets(130, 140) slantly installed to correspond to first and second steel plates on the truck.

PURPOSE: A wheel type super high speed tube railroad system is provided to reduce the degeneracy by setting an ARM(Axle-Load Reducing Magnet) at the lower unit of an axle among shaft. CONSTITUTION: Rails(110, 112) are installed on a tube type line(100) of an ball state. Wheels installed at a balance(220) of the vehicles is touched with the rail. A first and second exercise/control LSMs are respectively installed in both sides of the line and wheel. The first and second exercise/control LSMs push for the vehicles. The first and second exercise/control LSMs control the lateral of the vehicles by horizontally pulling the vehicles. A reduction magnet(140) is installed among shaft in the lower unit of the vehicles and line. The reduction magnet improves the readability by reducing the Axle load in the high speed area.
