Today to share the knowledge of wireless charging coil under the magnetic disc, which will also explain the installation of wireless charging coil magnetic disc, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>Different brands of mobile phones due to the difference in coil position, may lead to low charging efficiency or can not be charged. Do not use too thick or magnetic insulation of the phone case, the phone may not be charged or overheated resulting in damage. Please do not charge non-Qi standard wireless charging equipment, so as not to cause equipment failure or fever. Do not block the fan inlet and outlet that block the wireless charger.

Do not use too thick or magnetic insulation material mobile phone protective case, mobile phone may be damagedMethod charging or overheating causes damage. Do not charge non-standard wireless charging devices to avoid device failure or heat. Do not block the fan inlet and outlet that block the wireless charger.
Radio waves We all know that electromagnetic waves can be used to transmit information, so in theory, as long as the frequency is high enough, it can also transmit energy. This wireless charging method is perhaps the closest to what people imagine wireless charging looks like, an electromagnetic wave generator is placed at the power source, and then the energy is transmitted to the receiving antenna through the transmitting antenna, and then the electromagnetic wave signal is re-converted into electricity for the device.
You need to put the wireless charging chip into the phone, one side connected to the charging coil, the other side connected to the battery, which is the most basic.
Sometimes I feel that the wireless charging mobile phone is very magical, and I want to know how it is to achieve wireless charging, so I collect a lot of information and finally understand the principle, and I can take a look at this friend who is equally curious.
Wireless charging is a very practical technology that makes our lives more convenient. However, different mobile phone brands also have different levels of support for wireless charging.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic fieldIt generates an electric current that charges the phone.
is when the transmitting coil through the alternating electrical signal, the alternating electric field through the transmitting coil will produce a changing magnetic field, the changing magnetic field on the magnetic coupling of the coil around it, according to Faraday's law of electromagnetic induction, the changing magnetic field will produce an electric field. Therefore, the magnetic field generated by the transmitting coil will pass through the receiving coil, which will generate an electric field, and if a load is attached to the receiving coil, an electric current will be generated.
