2, wireless charging refers to the charger on the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. How to use: Connect the USB cable and plug it into the socket.
3, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the mobile phone without wire connectionThe wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Generally seen wireless charging, the use of the "current magnetic effect" and "electromagnetic induction" principle. In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generationsIt was further found that by encircling the wire into a ring, or even winding it into a coil, the magnetic field generated will be stronger and more concentrated, which is called the "current magnetic effect".
No strong radiation, no effect on the human body! The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it does not need to transmit electricity to the device like the traditional wired charger, but will need to be chargedThe electric device can be charged by touching the wireless charging base.
Hello, wireless charging uses the principle of electromagnetic induction, which is equipped with electromagnetic induction coils on the charging device and electromagnetic coils on the charged device.
1, can not, too much increase the voltage or increase the number of turns will burn the battery, because the more you turn the higher the voltage, I do not know your homemade chargerWhether it is Qi program, if it is Qi, it is not possible, this must be close contact, you have to change to radio wave type, within five meters.
2, no harm to mobile phones. Wireless charger uses the latest wireless charging technology, by using the alternating magnetic field generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
3, wireless charging will not accelerate battery aging, will not have radiation to the body. The principle of wireless charging is electromagnetic induction. The charging dock is like an iron core with some primary coils wrapped around it. Inside the phoneComes with secondary coil. The primary coil is energized to generate electromagnetic induction, so that the secondary coil generates induction voltage, and generates induction current to charge the mobile phone after loading. So don't worry.
The basic principle of wireless charging Zhaoqing wireless charging coil , that is, the current is converted into a magnetic field Zhaoqing wireless charging coil , and the magnetic field is transmitted through the air and converted into current to the intelligent terminal. systemmanAt the input end, the AC mains is converted into direct current through the full bridge rectifier circuit, or the 24V DC end is used to directly supply power to the system. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, and uses the latest wireless charging technologyBy using the magnetic field generated between the coils to magically transmit electrical energy, inductive coupling technology will become a bridge connecting charging base stations and devices.

In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that the wire is encircled into a ring, or even wound into a coil, and the magnetic field generated will be stronger and more concentrated, which is called the "current magnetic effect."
Wireless charging has an electromagnetic senseIn response, magnetic resonance, electric field coupling and radio wave transmission, 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 field will generate current, charging the mobile phone. As shown below.
1, wireless charging efficiency is related to power, the greater the general power generated by the greater the magnetic field range, the closer the distance is the better the efficiency, and the closer the receiving coil and sending coil, the higher the energy conversion efficiency, according to the size of the distance power efficiency from 100% to 0%. The distance is greater than 10 cm, and the conversion efficiency is only about 60%, that is, the sent power is 1000W, and the received power is only 600W.
2, wireless charging transmission, receiving module component specifications, the distance between the coil, the interval material material will affect the charging efficiency, there are a lot of wireless charger program related informationYou can check which use your wireless charging scheme is used for, and the charging efficiency of different technology schemes varies greatly.
3, according to the principle of physics, the stronger the electromagnetic coil will emit the stronger the magnetic field, and then the reception of the mobile phone is also related, the stronger the magnetic field, then the ability to charge will be stronger.
4, No. Each wireless charging coil will have a certain amount of energy loss, increasing the number of coils will lead to a decrease in the overall charging efficiency, more coils will increase the energy loss and mutual interference, thus reducing the efficiency of wireless charging; And increasing the number of coils needs to be installed in the deviceInstalling more coils and associated circuits increases design complexity and cost.
