The invention discloses a rapid wireless charging system for an unmanned aerial vehicle group. The system comprises an inversion module, a rectification module, a communication control module, a position detection module, a ground wireless transmitting system and an unmanned aerial vehicle wireless receiving system. The system adopts an electromagnetic induction type wireless transmission mode, the overall structure is a single-multiple-single model, one power supply module is connected with ten transmitting coils and performs switching control on the ten transmitting coils, and each transmitting coil corresponds to one receiving coil. A transmitting side rectifies 220V power frequency alternating current into direct current, the direct current is inverted into high-frequency alternating current, and the high-frequency alternating current is injected into a transmitting coil to be converted into a high-frequency alternating current magnetic field; the wireless receiving coil receives the high-frequency magnetic field and then converts the high-frequency magnetic field into high-frequency alternating current, and the high-frequency alternating current is rectified and regulated by the power conversion module to charge a battery of the unmanned aerial vehicle. According to the invention, the charging power and charging efficiency of the unmanned aerial vehicle can be increased, the charging convenience is realized, and the multi-load characteristic meets the requirement of charging the unmanned aerial vehicle group in special occasions.
