The so-called electromagnetic induction principle is that when a part of the conductor of the closed circuit cuts the magnetic induction line in the magnetic field, a current will be generated in the conductor. This phenomenon is called electromagnetic induction. The current produced by electromagnetic induction in a closed circuit is called induced current. It is the induced current that replaces the alternating current transmitted by the power adapter to complete the charging process of the mobile phone.
The wireless charger connected to the power supply excludes the patented technology of controlling current and magnetic flux parameters, and its essence is that a bunch of wires are regularly wound together. When 220V household alternating current is connected, a closed loop will be formed. Due to the action of alternating current, a magnetic field will be generated in the closed loop, and the magnetic flux of the magnetic field will change accordingly, which can be understood as the change of magnetic force.

Xiaomi has completed the technological transformation of charging innovation.
Xiaomi has always regarded charging innovation as an important direction of mobile phone technology application innovation. The 120W wired secondary charging and 80W wireless secondary charging have been mass-produced in the industry before, and both wired charging and wireless charging are in the leading position. The remote charging technology released by Xiaomi this time is another bold exploration in the field of charging, which opens up new possibilities for future charging scenarios.
So far, Xiaomi has built a set of remote charging system from remote charging pile to mobile phone terminal, and has 17 technology patents so far, which has overcome two core technologies: spatial positioning and remote energy transmission.
