Assembly consisting of an electric vehicle and a system for stationary charging by conduction; associated system, facility, vehicle and method

An assembly made up of an electric vehicle and a recharging system of a stationary conduction type for recharging said electric vehicle when stopped in a predetermined position allowing an energy capture from the recharging system, wherein the recharging system comprises:

• a power supply contact, positioned on the ground and associated with a current return, and
• a switching device to bring the power supply contact to a supply voltage delivered by an electric power source to which the recharging system is connected,
• wherein the electric vehicle comprises:
• a contact shoe electrically connected to an onboard energy storage, the contact shoe being placed below a body of the electric vehicle and movable between a high position, away from the power supply contact, and a low position, in contact with the power supply contact, and
• a control device able to command the movement of the contact shoe from the high position to the low position so that it is placed in contact with the power supply contact, only when the vehicle is stopped in said predetermined position, which is an energy capture position in which the footprint of the electric vehicle covers the power supply contact,
• wherein the assembly further includes a two-way communication equipment between the recharging system and the electric vehicle, including a ground transceiver connected to a ground antenna situated near the power supply contact, and an onboard transceiver connected to an onboard antenna, supported by the contact shoe, the ground transceiver transmitting a first signal continuously over a significant range, the onboard transceiver detecting the first signal in the high position and low position of the contact shoe, the first signal, when it is received, indicating that the contact shoe is over a power supply contact, the onboard transceiver transmitting a second signal over a reduced range, the ground transceiver detecting the second signal only in the low position of the contact shoe, the second signal, when received by the ground transceiver module, indicating that the contact shoe is in contact with the power supply contact.
