Wireless charging is a charging method that does not require the use of wires or plugs. It achieves wireless charging by transferring energy to the device that needs to be charged by means of electromagnetic induction or electromagnetic radiation.
Principle of wireless charging
The principle of wireless charging is to transfer energy to the device that needs to be charged by means of electromagnetic induction or electromagnetic radiation. Specifically, wireless charging is categorized into two ways: electromagnetic induction and electromagnetic radiation.
Electromagnetic induction: through the principle of electromagnetic induction, the current at the transmitting end is converted into a magnetic field, and then the energy is transferred to the receiving end through the magnetic field, which in turn converts the energy into current, thus realizing wireless charging.
Electromagnetic radiation: By means of electromagnetic waves, energy is transmitted from the transmitting end to the receiving end, which in turn converts the energy into current, thus realizing wireless charging.
Applications of wireless charging
Wireless charging has a wide range of applications, mainly used in the following areas:
Smartphones: there are already many smartphones on the market that support wireless charging, and the user only needs to place the cell phone on the charging mat to realize wireless charging.
Electric vehicles: charging of electric vehicles requires the use of charging piles, and wireless charging technology allows electric vehicles to be charged wirelessly while parked, thus making it convenient for users.
Medical equipment: Wireless charging technology allows medical equipment to be charged wirelessly, making it convenient for healthcare professionals.
Smart home: wireless charging technology allows smart home devices to realize wireless charging, which is convenient for users to use.
