A vehicle charging system includes a power transmitter including at least one voltage converter configured to allow a vehicle charging mode to be changed by a plurality of switches and a magnetic field generator configured to generate a magnetic field corresponding to a voltage converted by the voltage converter; and a power receiver including a current inductor configured to allow an electrical signal to be induced by the magnetic field generated by the magnetic field generator, a rectifier configured to rectify the induced electrical signal and a battery configured to be charged by the electrical signal rectified by the rectifier.

Vehicle, vehicle charging device, vehicle charging system and method for charging vehicle

A charging apparatus for an electric vehicle has a small-sized simple structure, and charges a battery of the electric vehicle upon receiving electricity from various kinds of power sources. The charging apparatus includes a motor, an inverter, an AC power input stage, a power factor, a link capacitor, a switch network, and a controller. The AC power input stage receives an AC input power from a single-phase AC power or a multi-phase AC power. The power factor corrector has a single three-leg half bridge circuit receiving the AC input power through the AC power input stage, and the link capacitor is charged through at least one of combinations of the power factor corrector, the motor, and the inverter. The controller controls the power factor corrector and the switch network based on a condition of AC input power received through the AC power input stage.

Charging apparatus for electric vehicle

A vehicle may include a first battery to output power of a first voltage, a second battery to output power of a second voltage, a DC-DC converter to convert the first voltage of the first battery into the second voltage, and to supply the power of the second voltage to the second battery. The DC-DC converter may include a transformer to convert the first voltage into the second voltage, a first switch to control first current input to the transformer from the first battery, a current sensor to measure a value of second current output to the second battery from the transformer, and a controller to turn on/off the first switch based on a set turning-on/off frequency. The controller may delay turning-on/off of the first switch based on the measured value of the second current.

Vehicle having a DC-DC converter, and a method of controlling the DC-DC converter for a vehicle

The present disclosure provides a vehicle, a vehicle charging apparatus, vehicle charging system, and a vehicle charging method. The vehicle charging apparatus may include: a first coil; a second coil having one end selectively connected to one end of the first coil, and the other end selectively connected to the other end of the first coil; a third coil having one end selectively connected to one end of the first coil, and the other end selectively connected to the other end of the second coil; and a fourth coil having one end selectively connected to one end of the second coil, and the other end selectively connected to the other end of the first coil, where the fourth coil intersects the third coil.
