The invention discloses an AUV (Autonomous Underwater Vehicle) wireless charging device with a new coil structure, which comprises a transmitting coil at a power supply end, a receiving coil at a power receiving end and an arc-shaped magnetic core for shielding a magnetic field, the transmitting coil surrounds the receiving coil inside, and the arc-shaped magnetic core is arranged outside the transmitting coil and inside the receiving coil. The transmitting coil is formed by connecting a plurality of transmitting arc-shaped coils in series along the circumference, and the receiving coil is formed by connecting a plurality of receiving arc-shaped coils in series or in parallel along the circumference; the structural characteristics of the transmitting coil and the receiving coil enable the inductance matrix parameter between the transmitting coil and the receiving coil to be a constant, the device is suitable for the AUV wireless charging device, the problem that the coupling coefficient of the traditional AUV wireless charging device changes along with the heeling angle of the AUV is solved, the coupling is good, and the reliability is high. The arc-shaped magnetic core shields the leakage magnetic field radiation generated by the transmitting coil or the receiving coil, the leakage magnetic field is very small, the electromagnetic radiation interference to the AUV is small, and the transmission efficiency is high.
