Title:
SAFE LOW-VOLTAGE CONDUCTIVE GROUND-INSTALLED CONNECTING DEVICE FOR STATICALLY AND DYNAMICALLY CHARGING ELECTRIC VEHICLES
Document Type and Number:
WIPO Patent Application WO/2023/067496
Kind Code:
A1
Abstract:
The invention relates to a device for supplying electric power to electric vehicles (139) comprising: one or more traction batteries; at least one current collector (140) integrated into the vehicles (139); and, in the ground, at least one fixed power duct substantially parallel to the direction of movement of the vehicles (139), comprising a vertical slit, which opens into a cavity of the duct for receiving the current collector (140), the cavity containing at least one electrical contact surface connected to a fixed current source by a power cable, the contact surface being located set back from a route of direct access through said slit, characterized in that the electrical contact surface is positioned in the cavity of the duct as an inclined cornice. This device is further characterized in that the slit has a width smaller than the safety standard according to which it must be impossible for a finger to be able to penetrate into the slit, which width is currently set to 12 mm in Europe (IEC 60529).
