what is wireless
The current wireless charging technology is constantly maturing, and the development of technology is steadily advancing. International standards are also gradually taking shape. So what is wireless charging? The principle behind wireless charging technology is the well-known electromagnetic induction phenomenon, specifically the use of a changing electric field to generate a changing magnetic field, and then the use of the changing magnetic field to generate an electric field, thereby generating current to charge the device.
The direction of the magnetic field generated around an energized wire is perpendicular to the direction of the current and is usually very weak. However, if the wire is wound in a circular or spiral shape, the magnetic fields in the same direction will be superimposed, forming a strong magnetic field. In fact, the principle of wireless charging is similar to the common transformer in our daily lives, which uses the current in one coil to generate current in another coil. But unlike the way transformers conduct magnetic fields through iron cores, the induction coils in wireless charging devices have undergone some special adjustments and use air as the medium to conduct magnetic fields, thereby generating induced currents. At the same time, just like the resonance of sound, the induction of two coils also requires setting a resonance frequency, so that the frequency of the receiving coil and the output coil are consistent, so that even when the output coil current is very small, enough strong induction current can be generated in the receiving coil.
The most common charging solution currently uses electromagnetic induction. By utilizing Faraday electromagnetic induction, a magnetic field is generated when current passes through the coil; The generated magnetic field will form a voltage, and with the voltage, a current will be generated, which can be charged. By inducing current through the primary and secondary coils, energy is transferred from the transmitting end to the receiving end. Current flowing through a coil generates a magnetic field. Other coils that are not energized will generate current when they approach the magnetic field. Through the physical phenomenon of "electromagnetic induction", energy can be transmitted from the left energy transmitting coil to the right energy receiving coil.
The Wireless Charging Consortium (WPC) mainly uses this method to achieve energy transfer, developing specifications for low-power applications of 5W, 10W, and 15W products, and is also attempting to develop specifications for high-power products. It can charge multiple appliances on a single plane, and the transmitting end of the charging board is relatively close to the receiving end of the charging product.
This scheme has been widely applied in practice, and Huagon, China wireless charging module manufacturers , our wireless charging products are all developed and researched based on this theoretical basis.
