  "textContent": "A wireless electricity transmission system includes: a wireless electricity transmission device and one or more wireless electricity reception devices installed within a vehicle. The wireless electricity transmission device includes an electricity transmission wave generation unit that generates a directional electricity transmission wave using beamforming, and a control unit that transmits query waves in directions and, when a pilot signal including identification information on a query wave having a maximum reception strength is received from the wireless electricity reception device, transmits the electricity transmission wave to the wireless electricity reception device in a direction of the query wave. The wireless electricity reception device includes a reception strength determination unit that determines the query wave having the maximum reception strength, a control unit that transmits the pilot signal including the identification information on the query wave having the maximum reception strength, and a reception unit that receives the electricity transmission wave.",
