POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/033356
Kind Code:
A9
Abstract:
The present invention relates to a power supply cable for an online electric vehicle, wherein the power supply cable can supply power to a power collector of the electric vehicle. 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.
