Mobile phone wireless charging coil
Mobile phone wireless charging coil is an important hardware component of wireless charging mobile phone technology, smart phone wireless charger requirements with small size, high precision, easy to carry, intelligent, high charging efficiency characteristics, this wireless charging technology is the majority of mobile phone manufacturers, because the novel charging technology makes the product in the market compared with the traditional charging watch more competitive.
Wireless charging comes from wireless power transmission technology. The principle is that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device then converts the received energy into electrical energy stored in the battery of the device. There are currently four major wireless charging solutions: electromagnetic induction charging, magnetic resonance charging, radio wave charging, and electric field coupling. At present, not only the application of wireless watch charging coils has been popularized, but the development bottlenecks of 5G, smart cities, smart homes, the Internet of Things, smart phones, new energy vehicles, driverless, and portable devices are also vigorously promoting the development of wireless charging technology.
