Abstract: With the increasing popularity of various electronic devices, people's demand for the portability of device charging is also increasing. Wireless charging technology has emerged and is showing a rapid development trend. Wireless charging technology utilizes the conversion effect of electric and magnetic fields, transmitting electrical energy wirelessly from the transmitting end to the receiving end, charging the battery of the receiving device. There is no need for a wire connection between the charging device and the electrical device, and the charging device and the electrical device's conductive contact points can be fully enclosed. This paper first introduces the origin and development of wireless charging technology. Then, it introduces the mainstream standards of wireless charging technology. The author mainly analyzes the structure and principle of two types of wireless charging technologies: electromagnetic induction and resonant. Then, it compares the two types of wireless charging technologies in terms of principle and transmission parameters. This paper summarizes the characteristics of both technologies above.Finally, it summarizes the application scenarios of wireless charging technology. This paper aims to provide literature support for the research on wireless charging technology.
