What are the characteristics of wireless charging technology in the field of mobile phones
2019-12-12 10:19:27

As we all know, wireless charging technology has developed rapidly in recent years. Although wireless charging technology can be used in mobile phones, notebook computers, small household appliances and other fields, the mobile phone industry has the largest market share. What are the characteristics of wireless charging technology in the field of mobile phones? What are its advantages and disadvantages?

First, simple principle.

The electromagnetic coupling principle of high school physics is also familiar to the industry, and the technology extended from RFID is also easy to accept. The receiving end is one or two chips (the final single chip scheme), one end is connected with the charging coil and the other end is connected with the battery. Many companies begin to launch a series of chips, which will speed up the spread and popularization of wireless charging knowledge.

Because of its simple principle, it is easy to make or understand. It is easy to be accepted by the public.

Second, troublesome technology.

The extra space in mobile phones, especially smart phones, is difficult to free up and place a large charging coil.

This round coil with a diameter of 40 mm, and a piece of inorganic magnetic material with a thickness of 0.8-2 mm (i.e. 0.2 mm for micro aero organic magnetic material) will be added below. The thickness of the mobile phone will be increased. If this component is placed on the circuit board of the mobile phone, it will occupy space and run other components.

Therefore, all the engineers who design the structure of mobile phones have a headache, which restricts or hinders the development of wireless charging products and becomes a roadblock.

Some companies have launched 0.53mm thick wireless charging receiving coil (antenna), hoping to promote the popularization of wireless charging technology in mobile phones.

Nowadays, smart phones are developing in the direction of small and thin. If the volume of wireless charging coil is large, it will lead to the increase of smart phone volume, which is contrary to the development direction of mobile phones.

These are the development characteristics of wireless charging technology in the field of mobile phone charger. Although it is still restricted by many. But in the end, mobile phone charging is still the world of wireless chargers.
