Disclosed herein is a battery charger for electric vehicle includes a motor configured to generate power for driving the electric vehicle, an inverter configured to provide the power to the motor, an AC power input terminal configured to be input at least one AC power of single phase AC power and polyphaser AC power from a slow charger, a power factor corrector configured to include a plurality of full bridge circuits through which the AC power is input through the AC power input terminal, a link capacitor configured to connect in parallel with the power factor corrector, a switch network configured to include a first switch SW A provided to connect any one of a plurality of AC power input lines and a neutral line constituting the AC power input terminal with the power factor corrector, and a second switch provided to transfer one of a direct current power input from a quick charger and an alternating current power input from a slow charger to a high voltage battery and a controller configured to control the power factor corrector and the switch network according to the conditions of the AC power and the DC power.

Battery charger for electric 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 charging apparatus for an electric vehicle is provided. The apparatus charges a vehicle battery upon receiving power from different power sources. The apparatus includes a motor generating power to drive the electric vehicle and an inverter supplying power to the motor. An AC power input terminal receives at least one of single-phase AC power and multi-phase AC power. A power factor corrector having a single three-leg half bridge circuit receives the AC input power through the AC power input terminal. A link capacitor is charged through a combination of the power factor corrector, the motor, and the inverter. A switch network has at least one switch for selectively connecting the AC power input terminal to the power factor corrector, the link capacitor, the motor, or the inverter. A controller operates the power factor corrector, the switch network, and the inverter based on a condition of received AC input power.

Disclosed herein is a charging apparatus for an electric vehicle. The charging apparatus includes a motor generating a power for vehicle driving. An inverter supplies a power to the motor. An alternating current (AC) power input stage receives an AC input power from among a single-phase AC power and a multi-phase AC power. A power factor corrector includes full bridge circuits receiving the AC input power through the AC power input stage. A link capacitor is charged through a combination of the power factor corrector, the motor, and the inverter. A switch network has a first switch connecting one of an AC power input line and a neutral line of the AC power input stage to the power factor corrector and a second switch selectively connecting the AC power input stage to the power factor corrector or the link capacitor. A controller operates the power factor corrector and the switch network based on a received AC input power condition.

A controller operates the power factor corrector and the switch network based on a received condition of the at least one AC input power.

A vehicle electronic module is provided. The vehicle electronic module has a reduced size and improved productivity by replacing a sensor and an offset unit of an electromagnetic interference (EMI) filter module with a printed circuit board (PCB) winding structure. The electronic module includes a sensor that detects EMI noise of a power line and an offset unit that transmits an offset voltage for removing the EMI noise to the power line. A controller is configured to generate the offset voltage that corresponds to the EMI noise detected by the sensor. Then sensor and the offset unit are formed in a stacked structure of the PCB.
