SEW (Wireless Power Transmission) is a wireless charging scheme that enables the power transmission of wireless charging devices. SEW wireless charging scheme based on the principle of electromagnetic induction, through the transmission of electrical energy from the transmitter to the receiver, to achieve wireless charging of electronic devices.

SEW wireless charging schemes typically include two main components: a transmitter and a receiver. The transmitter is usually a charging base station or charging pad that transmits electrical energy by connecting to a power source and generating an electromagnetic field. The receiver is embedded in the device that needs to be charged, and can receive and convert the energy in the electromagnetic field, converting it into electricity for the device to charge.

The benefits of SEW wireless charging solutions include convenience, the need to plug and unplug and the use of charging cables, as well as protection and water resistance for devices. However, it is important to note that the efficiency and charging speed of SEW wireless charging schemes can be affected by a number of factors, such as distance, position alignment, transmitter and receiver power, etc. Therefore, when selecting and using SEW wireless charging solutions, they need to be evaluated and selected according to specific application needs and device compatibility.
