  "textContent": "This application discloses a coil winding, and belongs to the field of wireless charging technologies. The coil winding includes: an insulation layer, a first part of coils located on one side of the insulation layer, and a second part of coils located on the other side of the insulation layer. The first part of the coil comprises a first segment of conducting wire, the second part of the coil comprises a second segment of conducting wire. The first segment of conducting wire and the second segment of conducting wire each are provided with N cutting openings. The first segment of conducting wire is divided into N+1 first sub conducting wires by the N cutting openings provided on the first segment of conducting wire. The second segment of conducting wire is divided into N+1 second sub conducting wires by the N cutting openings provided on the second segment of conducting wire. The N+1 first sub conducting wires and the N+1 second sub conducting wires are electrically connected in a one-to-one manner, to form N+1 pairs of sub conducting wires. At least one crossover structure is formed in the N+1 pairs of sub conducting wires. In this application, a circulating current loss in the coil winding can be reduced, and wireless charging efficiency can be improved. In addition, this application further discloses a corresponding coil module, a wireless charging transmitting apparatus, a wireless charging receiving apparatus, a wireless charging system, and a terminal.",
