In the 1890s, Nikola Tesla, an assistant to Edison's spectral radiant energy research project and a future scientist, confirmed the possibility of wireless transmission of radio waves and filed the first patent.
2, wireless charging system mainly uses the principle of electromagnetic induction, through the coil for energy couplingCombined to achieve the transfer of energy. As shown in the figure, when the system works, the input end converts the AC mains into direct current through the full-bridge rectifier circuit, or uses the 24V DC end 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.
3, the reason why mobile phones can achieve wireless charging is to rely on electromagnetic induction, radio waves, magnetic resonance and electric field coupling and other ways to achieve. Its different ways, based on the relevant principles are not the same, the details are as follows. Electromagnetic induction wireless charging principle This wireless charging method is the current marketThe relatively popular principle of wireless charging depends on the effective conversion of magnetic energy and electric energy. 4, we usually think that electricity and magnetism are related, so in talking about the principle of wireless charging, mostly based on electromagnetic induction phenomenon or derived from it. At present, there are four main ways to achieve wireless power transmission: magnetic field induction to a certain frequency of alternating current in the primary coil, through electromagnetic induction to generate a certain current in the secondary coil, so as to transfer energy from the transmission end to the receiving end.
5, wireless charging system mainly uses the principle of electromagnetic induction, through the coilEnergy coupling is carried out to realize energy transfer. As shown in Figure 1, when the system is working, the input end converts the AC mains into direct current through the full-bridge rectifier circuit, or uses the 24V DC end 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. 6, due to the relatively mature wireless charging technology, it has been put into use in some places abroad, in 2014, South Korea laid a 12-kilometer wireless charging road, vehicles driving on the road can be charged while driving. The working principle utilizes physicsThe principle of "resonance" - two objects that vibrate at the same frequency can transmit energy efficiently. The electrical energy from the transmission line goes to the antenna made of copper.
Self-made wireless charger 1: External module installation Procedure Attach the module to a place far from the MicroUSB interface. Step Connect the MicroUSB or Lightning port on the module to the phone. Steps If there is double-sided tape on the receiver, you can glue it directly to the back of the phone. If it doesn't come with it, thenI figured it out myself. Step to select the most appropriate position, be careful not to let the part of the connection line warped phenomenon.
Self-made mobile phone wireless charging methods are as follows: Prepare materials: mobile phone charger First cut the USB charging cable not far from the two ports into two sections. Use scissors to separate the tail glue of the two wires into a section to screen and then cut off the green wire with a double bottom line. Use hot glue to attach the magnet to the charger. Wrap the wires in the USB with tinfoil. Then wrap the wires and roll them up with copper wire.
To add wireless charging function to ordinary mobile phones, the most critical is installationA wireless charging receiver. This process usually involves opening the case of the phone, finding where the battery or battery is connected, and welding or connecting the receiver to the appropriate circuit. This requires a certain amount of electronic knowledge and fine manual skills, because the components inside the phone are very small and fragile.

The method of making a wireless charger is as follows: Attach the module to the place where the MicroUSB interface is compared. Connect the MicroUSB or Lightning port on the module to your phone. If there is double-sided tape on the receiver, you can glue it directly to the back of the phone. If it doesn't come with it, you have to figure it out yourself. Choose the most suitable position, be careful not to let the part of the connection line have the phenomenon of warping.
Soldering iron, copper wire, resistor, transistor, capacitor. That will do. So wireless charging is simple. But I suggest you don'tHave done it. It's all special materials. If you do it for fun, just make an oscillating circuit.
One of the self-wound coil is connected in the charging circuit, 555 output pin (third pin) is connected to an output tube (oneself at will, but to the high-frequency power tube) the output tube is linked to the self-wound coil, and the connected two coils are close (about 1 cm or so there is a very sufficient charging current). The efficiency of this circuit is very low, because there is only half a wave peak high frequency so the loss is relatively large, but the principle is quite simple and easy to produce.
Yes, but not too long.Too long affects the overall performance of the machine.
Thus, the point energy is transferred from the transmitting end to the receiving end, and it begins to power the phone from the charging seat because the principle is simple and easy to make, coupled with the promotion of Texas Instruments, Philips, Toshiba, Microsoft, Panasonic, Samsung, SONY, Qualcomm and other manufacturers, which is the most popular way on the market. However, wireless charging based on electromagnetic induction also has disadvantages, among which the transmission distance is severely limited.
