As technology advances at a rapid pace, autonomous ships are becoming increasingly prevalent in various fields such as marine transportation, environmental monitoring, and military patrols. These ships not only require advanced navigation and data analysis capabilities but also need efficient and reliable energy replenishment systems. Traditional wired charging methods have many limitations, such as easily damaged charging interfaces and poor environmental adaptability. Therefore, wireless charging technology has gradually become a research hotspot in the field of autonomous ships.

Wireless charging technology transmits electrical energy without physical contact through methods such as electromagnetic induction and resonant coupling. This charging method not only enhances the autonomy and flexibility of autonomous ships but also significantly reduces maintenance costs. Electromagnetic induction charging is relatively simple and suitable for small autonomous ships. It works by using the magnetic field changes between a transmitting coil and a receiving coil to transfer energy to the ship's battery. However, this method has limitations in terms of transmission distance and efficiency, making it unsuitable for larger ships.

To address these limitations, resonant coupling charging technology has emerged. This technology leverages the resonant effect of two or more resonant coils to achieve longer-distance and more efficient energy transmission. A resonant coupling charging system consists of a transmitter module, a receiver module, and a control module. Through precise control techniques and advanced computational algorithms, it ensures the safety and stability of the charging process. This technology is not only suitable for larger autonomous ships but can also maintain efficient charging in complex and dynamic marine environments.

The application of wireless charging technology in autonomous ships significantly improves their endurance and operational efficiency. For example, marine environmental monitoring ships can freely move between charging stations without the need to frequently return to base for wired charging, thus reducing downtime. Moreover, wireless charging technology can be integrated with other intelligent systems to achieve automated charging management. Using sensors and communication devices, autonomous ships can automatically identify the location of charging stations and charge autonomously when needed, further enhancing their autonomy.

In the future, as wireless charging technology continues to advance, autonomous ships will be able to be applied more broadly in various scenarios. Researchers are exploring more efficient and longer-range wireless charging solutions while also developing more intelligent charging management systems. These innovations will enable autonomous ships to play a greater role in future marine technology.
