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 system and a method of controlling charge of a vehicle battery are provided. In particular, when a voltage of the vehicle battery is different from an output voltage of a commercially available quick charger, a compatibility problem is solved through a converter, thereby allowing an inverter, an electric motor, and a connector to have an increased efficiency and to maximize a reduction in size, weight, and material cost thereof.

System and method of controlling charge of vehicle battery

An electric vehicle includes: a battery configured to be charged with a first voltage; and a converter configured to boost, when power of a second voltage that is lower than the first voltage is received, the power of the second voltage to the first voltage, and to transfer the first voltage to the battery, so that the battery is charged with power of the first voltage, wherein when the power of the first voltage is received, the power of the first voltage is transferred to the battery to charge the battery.

Electric vehicle

A power net system of a fuel cell hybrid vehicle includes a fuel cell and an electric vehicle battery (EV battery) connected with each other through a main bus terminal in parallel, and an insulated gate bipolar mode transistor (IGBT) connected to the EV battery and the main bus terminal. The power net system further includes an inverter connected to the main bus terminal and a driving motor connected to the inverter.
