Wireless power transfer system, supply device, and vehicle

A supply device comprising:

• a primary device including a primary coil installed on a road;
• a first communication device that performs narrow-area wireless communication with a vehicle;
• a second communication device that performs wide-area wireless communication with a server;
• and
• a control device that controls the primary device, the first communication device, and the second communication device, wherein
• the supply device transfers power in a non-contact manner from the primary coil to the vehicle traveling on the road,
• the second communication device
• transmits identification information of the supply device to the server before the first communication device receives a signal from the vehicle by the narrow-area wireless communication, and
• receives, from the server, a compatibility list in which information of the vehicle compatible with the supply device is listed, and
• the control device performs pairing with the vehicle on a basis of the compatibility list in a case where the first communication device receives the signal from the vehicle by the narrow-area wireless communication.

A vehicle comprising:

• a secondary device including a secondary coil that receives power transferred in a non-contact manner from a primary coil installed on a road;
• a third communication device that performs narrow-area wireless communication with a ground-side supply device including the primary coil;
• a fourth communication device that performs wide-area wireless communication with a server;
• and
• a control device that controls the secondary device, the third communication device, and the fourth communication device, wherein
• the vehicle receives the power transferred from the primary coil in the non-contact manner while traveling on the road,
• the fourth communication device transmits, in a case where the vehicle during traveling is in a state of being capable of receiving the power, identification information of the vehicle to the server,
• the third communication device transmits the identification information of the vehicle to the ground-side supply device while the vehicle is traveling on the road, and
• the control device performs pairing with the supply device by the narrow-area wireless communication with the supply device.
