Wireless charging is a charging method that does not use wires or plugs. It transfers energy to the equipment that needs charging through electromagnetic induction or electromagnetic radiation, so as to realize wireless charging.
The principle of wireless charging
The principle of wireless charging is to transfer energy to the equipment that needs charging through electromagnetic induction or electromagnetic radiation. Specifically, wireless charging can be divided into electromagnetic induction and electromagnetic radiation.
Electromagnetic induction: Through the principle of electromagnetic induction, the current at the transmitter is converted into a magnetic field, and then the energy is transferred to the receiver through the magnetic field, and then the energy is converted into current, thus realizing wireless charging.
Electromagnetic radiation: by means of electromagnetic waves, energy is transmitted from the transmitting end to the receiving end, and then the energy is converted into current, so as to realize wireless charging.
Application of wireless charging
Wireless charging is widely used, mainly in the following aspects:
Smart phones: There are many smart phones that support wireless charging on the market. Users only need to put their mobile phones on the charging board to realize wireless charging.
Electric vehicle: Electric vehicles need charging piles, and wireless charging technology can make electric vehicles wirelessly charge when parking, which is convenient for users.
Medical equipment: wireless charging technology can make medical equipment wirelessly charged, which is convenient for medical staff to use.
Smart home: Wireless charging technology can enable smart home devices to realize wireless charging, which is convenient for users to use.
