POWER FEEDING AND CURRENT COLLECTING SYSTEM FOR ON-ROAD WIRELESS CHARGING OF ELECTRIC VEHICLE AND INDUSTRIAL MACHINE

摘要

The present invention relates to a power feeding and current collecting system for wireless charging and, more specifically, to a power feeding and current collecting system for on-road wireless charging of an electric vehicle, such as an electric bus, electric car, tram, light rail vehicle and subway, and an industrial machine comprising a rubber tyred gantry crane (RTGC). According to the present invention, by resolving the problem of internal pressure on an existing power feeding line by means of a capacitor provided in "an inverter" or "a box" positioned outside the road and a power feeding line design and a common line placement design, an on-road wireless power feeding line can be expanded, and the economic efficiency of the wireless charging system is greatly enhanced due to such expandability. Provided is a power feeding system for wireless charging which sufficiently satisfies such compatibility at a lower cost. The magnetic field offsetting effect is maximized by means of the structure of the common line and a shielding pipe, and thus the electromagnetic interference (EMI) of the power feeding line is reduced.
