Wireless socket charging is to realize the energy transmission between the power supply and the electrical equipment in a non-contact way, which has the advantages of high conversion efficiency and short distance charging.
The principle of wireless socket technology is that a changing current flows through the coil to produce a changing magnetic field, and the adjacent pair of coils are coupled to produce a corresponding voltage for charging.
When the current passes through the coil, a magnetic field is generated, and when the magnetic flux of the closed circuit changes, an induced electromotive force is generated.
The charging base is responsible for turning the current into a magnetic field, and it is a constantly changing magnetic field.
There is a coil under the back cover of the phone, and because the magnetic field of the base is constantly changing, the magnetic flux in the coil is also constantly changing, generating an induced electromotive force for charging.
With the continuous development of high-tech in our country, there are now many charging and do not need to use a charging line, because they directly use Bluetooth, directly connected to charge, so, with the continuous development of science and technology, people use these things more and more convenient, more and more easy to use, you rest assured, his quality, for safety is very good, Like this is a trend that is constantly developing in a country
