摘要： The present invention relates to a current-collecting apparatus for an electric vehicle, which collects current using an electromagnetic field generated by an external source. The current-collecting apparatus for an electric vehicle according to the present invention is configured such that a current-collecting coil is wound around a current-collecting core in the direction of the electromagnetic field such that the current-collecting coil is distributed in the direction in which the electromagnetic field is generated. As the current-collecting coil is wound into a loop around the current-collecting core such that the current-collecting coil is distributed in the direction in which the electromagnetic field is generated, it is possible to minimize the electromagnetic field generated by the current-collecting apparatus without significantly influencing the electromotive force induced in the current-collecting apparatus.

The power supply cable for an electric vehicle comprises: a first cable portion in which current flows in one direction, and which is arranged near an edge of a road; a second cable portion in which current flows in the direction opposite that of the current in the first cable portion, and which is arranged near another edge of the road; a third cable portion in which current flows in the direction opposite that of the current in the second cable portion, and which is opposite one side of the second cable portion and arranged near yet another edge of the road; a fourth cable portion in which current flows in the direction opposite that of the current in the third cable portion, and which is opposite one side of the first cable portion and arranged near yet another edge of the road; a first connection portion extended and bent from the first or third cable portion so as to interconnect the first cable portion and the third cable portion; and a second connection portion extended and bent from the second or fourth cable portion so as to interconnect the second cable portion and the fourth cable portion, wherein the first connection portion and the second connection portion cross each other. Thus, electromagnetic fields generated at the edge of the road and electromagnetic fields generated in an X-shaped internal section (non-supply section) of the road during charging conducted while the online electric vehicle is stopped are reduced. According to the present invention, the power supply cable for an electric vehicle is bent in a predetermined direction, to thereby offset and reduce electromagnetic fields generated at the edge of the road.

摘要： The invention relates to an apparatus for shielding an electromagnetic field of a dual rail power supply system for an on-line electric vehicle, comprising: a power supply rail buried under a road and extending along the lengthwise direction of the road; a power supply core electrically insulated from the power supply rail and arranged beneath the power supply rail; a power-collecting device to which power is supplied from the power supply rail through electromagnetic induction; and shielding members arranged at either side of the power supply core so as to shield electromagnetic fields generated by the power supply rail and the power-collecting device. According to the present invention, a loop-shaped porous mesh made of SUS materials is buried underground up to a predetermined depth so as to reduce the intensity of electromagnetic fields generated by a power supply/collecting device of the on-line electric vehicle. Thus, electromagnetic fields are consumed, as current, by the loop-shaped porous mesh buried underground, even when the output from the power-collecting device increases, and therefore the level of electromagnetic fields satisfies the reference level 62.5mG, and the number of shielding plates attached to lower portions of conventional vehicles can be reduced.
