When the current passes through the coil, a magnetic field is generated, and wireless charging is such a process.
The charging base is responsible for turning the current into a magnetic field, and it is a constantly changing magnetic field. There is a coil under the back cover of the phone, and because the magnetic field of the base is constantly changing, the magnetic flux in the coil is also constantly changing, generating an induced electromotive force for charging. By the way, the metal has the effect of electromagnetic shielding, so the metal body of the mobile phone, there is no wireless charging. So at present, the back cover of wireless charging is either glass, ceramic, or plastic
First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger. Second, it conquers wireless charging. Versatility " In the near future, mobile phones, cameras, computers and other products can be charged with Qi wireless chargers, providing the possibility for large-scale applications of wireless charging.
& # 34; Qi" This icon is " in Chinese; Gas; The Pinyin (Qi), meaning is " Represents in Asian philosophy. Vitality " - An invisible energy. The Qi wireless charging system consists of base stations and mobile devices. The base station contains one or more emitters that provide the energy to be received.
The Qi wireless charging system consists of base stations and mobile devices. The base station contains one or more emitters that provide the energy to be received. The mobile device contains a receiver that provides power to the load (such as a battery), and the receiver also provides information to the transmitter. An energy conversion unit in the transmitter converts electrical energy into a wireless energy signal, and an energy collection unit in the receiver converts the wireless energy signal into electrical energy. The receiver will deliver power to the load as needed, and the transmitter will adapt the energy transfer according to the needs of the receiver.
