An embodiment apparatus for an electric vehicle includes an indoor power outlet configured to receive power through one of a plurality of lines except for a single-phase alternating current (AC) charging line among three-phase AC input lines, a sensor configured to measure a required current of an electronic device connected to the indoor power outlet, and a controller configured to control a bidirectional on board charger of the electric vehicle based on the required current.

Apparatus and method for controlling bidirectional on board charger of electric vehicle

An embodiment bidirectional charging system for a vehicle includes a first bridge circuit having a plurality of legs each including two first switching elements connected in series with each other between both ends of a battery, a transformer comprising a plurality of primary-side windings connected to a grid or load side and a plurality of secondary-side windings insulated from the plurality of primary-side windings, a motor including a plurality of input terminals configured to receive a plurality of phase voltages, respectively, a plurality of changeover switches configured to selectively connect connection nodes of the two first switching elements included in the plurality of legs to the plurality of secondary-side windings or to the plurality of input terminals, respectively, and a controller configured to control connection states of the plurality of changeover switches according to a pre-configured operation mode.

Bidirectional charging system for vehicle

A charging apparatus for an electric vehicle is provided. The apparatus includes an AC power input terminal receiving one AC input power from among single-phase AC power and multi-phase AC power. A power factor corrector having full bridge circuits receives the AC input power through the AC power input terminal. A link capacitor is charged through the power factor corrector. A first switch connects any one of an AC power input line and a neutral line of the AC power input terminal to the power factor corrector and a second switch selectively connects the AC power input terminal to the power factor corrector, or the link capacitor. The power factor corrector and the switch network operate based on a condition of received AC input power. The second switch includes a third switch and a fourth switch that connect each full bridge circuit to a positive battery electrode.

Charging apparatus for electric vehicle

A power conversion apparatus, a method for controlling the same and a vehicle including the same is provided. The power conversion apparatus includes a first power conversion portion having a first end connected to a first battery and a second end selectively connected to at least one of a power-supply portion and a second battery, a second power conversion portion having a first end connected to the first battery and a second end connected to the second battery. The second power conversion portion is configured to provide power supplied from the first battery to the second battery. A switching portion is configured to connect any one of the power-supply portion and the second battery to the first power conversion portion.
