Secured "low voltage" sliding conductive connection device for static and dynamic charging of electric vehicles and associated methods

Connection device for electrical conductive, dynamic and static charging of electrically propelled vehicles comprising one or more traction batteries, one current collector (70, 100, 140, 140′, 200) on board the vehicles, and one fixed conduit (1, 1′, 60, 120, 300, 301) for power supply from the pavement (16), the conduit being substantially parallel to the direction of the displacement of the vehicles, comprising a vertical slit (12) opening into a cavity (8, 8′) of the conduit (1, 1′, 60, 120, 300, 301) to receive, the current collector (70, 100, 140, 140′, 200), the cavity (8, 8′) containing at least two electrical contact surfaces (2, 2′, 3, 3′, 123, 124, 125, 126, 135, 136) connected to a fixed current source, the contact surfaces (2, 2′, 3, 3′, 123, 124, 125, 126, 135, 136) being recessed from direct access through the slit (12) and positioned in inclined overhang (1, 1′, 60, 120, 300, 301), wherein:

• the cavity (8, 8′) of the conduit (1, 1′, 60, 120, 300, 301) has dual entry capability and allows to be entered, for establishing conductive electrical connection, either:
• vertically by the current collector (140, 140′, 200) through the vertical slit (12) or
• horizontally by another current collector (70, 100) through at least one entrance (95) located at one end of the conduit for static charging,
• the connection is established on at least three cables (5, 6, 5′, 6′, 7a, 88, 63), one of which is connected to the “ground” (7a, 7b, 63),
• the vertical slit (12) of the fixed conduit (1, 1′, 60, 120, 300, 301) having a width “L” of less than 12 mm, and
• the vertical entry collector (140, 140′, 200) comprises two current shoe carriers articulated on longitudinal horizontal axis (163, 208), the rotation of the current shoe holder (160a, 160b, 171a, 171b), around the longitudinal horizontal axis (163, 208), between the vertical entry/retrieval position and the lateral connected position, being less than 60 degrees.
