With the continuous development of charging technology, wireless charging technology has officially entered the application stage, but many users do not know how to use the wireless charger function of their phones.
The principle of wireless chargers is actually to charge devices using the principle of electromagnetic induction. The principle is similar to transformer equipment. Requires transmitting and receiving devices. The transmitting device converts the current into an electromagnetic signal, and then the receiving device converts the received electromagnetic signal back into current, which is the principle of a wireless charger.
From the current wireless charging technology, there are three ways of wireless charging. One is electromagnetic induction, which generates current through electromagnetic induction between the primary and secondary coils; Another type is radio, which was first used for space communication. It mainly relies on circuits with efficient reception performance to capture radio waves in the air, and then convert them into electrical energy; The last type is electromagnetic resonance, but this technology is not yet mature and is still in the laboratory research and development stage, and has not been applied to mobile phones.
The use of wireless charging for mobile phones. For most ordinary users, wireless charging is still a new thing. Due to a lack of understanding of wireless charging methods, they do not know how to use their phones for wireless charging.
In fact, its usage is completely foolish. Although it involves the conversion of electromagnetic and current, they are all completed by equipment. Generally speaking, wireless chargers are disc-shaped, and some are embedded and slot type. However, regardless of the type, as long as the phone has wireless charging function and is close to the tray of the wireless charger, the phone will enter charging mode.
However, due to the limited transmission power of the charger, most wireless chargers need to be tightly connected to the phone, and the tightly connected part depends on the position of the wireless receiving device. As is well known, most mobile phones will have a wireless receiving device installed on the middle back of the phone, directly placing the phone on the tray of the wireless charger for wireless charging.
