Wireless charging technology has developed rapidly in recent years, and has gradually become an important direction of automatic charging of AGV (automatic guided vehicle). With the continuous improvement of industrial automation, AGV is more and more widely used in logistics, manufacturing, warehousing and other fields, and the requirements for charging technology are becoming more stringent. The traditional contact charging method has many limitations, such as the need for accurate docking, charging station occupies a large space, high maintenance costs, and wireless charging technology can effectively solve these problems, providing a new solution for the efficient operation and intelligent management of AGV.

The core of wireless charging technology is to use electromagnetic wave or electromagnetic induction principle to achieve non-contact transmission of electric energy. This technology can not only avoid the problem of charging interruption caused by poor contact, but also reduce the wear and failure rate of the charging interface and extend the service life of the AGV. In addition, the flexibility of wireless charging technology allows AGVs to be charged at any time during operation, without the need to stop specifically for charging operations, which greatly improves work efficiency.

In practical applications, wireless charging technology can be seamlessly connected with the AGV's navigation and scheduling system to achieve non-sensing charging. After completing the task, the AGV will return to the designated parking space, and the wireless charging device under the parking space will automatically start to charge the AGV. This automatic charging method not only reduces manual intervention, but also improves the reliability and safety of charging. At the same time, through the intelligent scheduling system, the power status of the AGV can be monitored in real time, and the charging time can be reasonably arranged to avoid work interruption caused by insufficient power.

Wireless charging technology also has significant cost advantages. Although the initial equipment investment is high, in the long run, the maintenance cost and failure rate of wireless charging systems are much lower than that of contact charging systems. For example, the contact charging interface is vulnerable to harsh environments, such as dust, water vapor, etc., while the wireless charging system can avoid the interference of these external factors and reduce the maintenance frequency. In addition, wireless charging technology can realize the modular design of the charging device, when a certain part fails, only the corresponding module needs to be replaced, without the need to ｒｅｐｌａｃｅ the entire device, further reducing maintenance costs.

In the future, with the continuous maturity of wireless charging technology and the further reduction of cost, its application in the field of AGV will be more extensive. Wireless charging can not only improve the operational efficiency and reliability of AGVs, but also provide a more flexible, efficient and safe solution for industrial automation. Researchers and engineers are working to develop wireless charging technologies with higher power and longer transmission distances that can meet the needs of larger AGV systems. At the same time, the standardization of wireless charging technology will also promote the interconnection between different brands and models of AGVs, providing more possibilities for intelligent logistics and intelligent manufacturing in the future.

In short, wireless charging technology is undoubtedly the future trend of AGV automatic charging. It has significant advantages in improving work efficiency, reducing costs, and enhancing system reliability, and will become an important technical support in the field of industrial automation. With the continuous progress of technology and the gradual popularization of applications, wireless charging has a very broad prospect in the field of AGV.
