Patent ID: 8365888

Claim:
A tile for forming a ground power supply line comprising: a supporting structure made of electrically insulating material; an external conductive plate, arranged on an upper surface of said supporting structure and fixed to said supporting structure; wherein said supporting structure has: a first channel for a first portion of conductor which, in use, is connected to a first polarity of an electric generator; a second channel for a second portion of conductor which, in use, is connected to a second polarity of said electric generator; said second channel being parallel and electrically isolated from said first channel; and an electric connection assembly, which is accommodated in said supporting structure and includes: an electric connector in contact with said external conductive plate along said upper surface, a pair of electric connectors arranged at said first and second channels, respectively, to come in contact with said first and second portions of conductor; a normally open switching element; and a control and command circuit for switching said switching element and selectively electrically connecting said external conductive plate to said first and second portions of conductor in response to a signal deriving from an electric vehicle passing over said external conductive plate; wherein said supporting structure comprises: a base which may be fixed to the ground by means of connection devices; an upper block defining said upper surface and accommodating said electric connection means; and fixing member fixing said upper block to said base.
