bring the power supply contact to a supply voltage delivered by a source to which the recharging system is connected, and a vehicle including a contact shoe electrically connected to onboard energy storage means, the contact shoe being placed below the vehicle and movable between a high position and a low position, the vehicle including 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 allowing the capture of energy from the recharging system, in which the footprint of the vehicle covers the power supply contact. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The assembly according to claim 1, wherein the control device detects that the contact shoe, once placed in contact with the power supply contact, is brought to a power supply potential and, consequently, electrically connects the contact shoe to the onboard energy storage by commanding the closing of an onboard switch. ### Claim 3 (depends on 1) The assembly according to claim 1, wherein the electric vehicle is a vehicle guided along a track including at least one metal rail, and the current return is made up of said metal rail connected to a reference potential. ### Claim 4 (depends on 1) The assembly according to claim 1, wherein the electric vehicle is a non-guided vehicle and the current return comprises of a reference contact connected to a reference potential. ### Claim 5 (depends on 1) The assembly according to claim 1, wherein the command device comprises, in series between the source and the power supply contact, a main contactor and a disconnecting switch, making it possible to place the power supply contact exclusively either at the power supply potential or the reference potential. ### Claim 6 (depends on 5) The assembly according to claim 5, wherein the command device comprises a contactor in parallel of the main contactor and the disconnecting switch. ### Claim 7 (depends on 1) The assembly according to claim 1, wherein the power supply contact comprises a conductive track, with which the contact shoe of the electric vehicle comes into contact, and an insulating soleplate fastening the power supply contact on the ground of the track, the insulating soleplate comprising a peripheral channel for receiving the ground antenna. ### Claim 8 (depends on 1) The assembly according to claim 1, delivering a power of about 1 MW, the power supply potential being between 600 V and 1000 V. ### Claim 9 (depends on 1) A recharging system of the stationary conduction type, wherein, in order to cooperate with an electric vehicle so as to form an assembly according to claim 1, the recharging system recharging the electric vehicle when stopped in a predetermined position allowing the energy capture from the recharging system, the recharging system comprises: a power supply contact, positioned on the ground and associated with a current return, a switching device bringing the power supply contact to a supply voltage delivered by an electricity 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 vehicle and movable between a high position, away from the power supply contact, and a low position, in contact with the power supply contact, the electric vehicle including a control device for commanding 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 vehicle covers the power supply contact. ### Claim 10 (depends on 9) A power supply facility for an electric vehicle, including a plurality of recharging systems according
