Abstract: With the increasing application demands of unmanned underwater vehicles in various marine exploration missions, underwater energy supply has become one of the major bottlenecks restricting their performance enhancement and application expansion. Traditional battery-powered methods are limited by endurance and operational duration, failing to meet the requirements for long-term and continuous operation. As an innovative energy transmission approach, underwater acoustic wireless charging technology leverages the propagation characteristics of sound waves in water to provide a non-contact, long-distance wireless charging solution. This paper investigates key technologies in underwater acoustic wireless charging, including the design and fabrication of high-power, highly directional transducer arrays for transmission and reception. To address the energy needs of underwater vehicles for prolonged continuous operation, this study proposes a prototype development plan for a long-distance underwater acoustic wireless charging system and conducts relevant validation tests in a anechoic tank environment.
