Wireless charging breaks new ground for smartphones Hefei low power wireless charging scheme Charging mode Hefei low power wireless charging scheme , get rid of the shackles of the traditional charging data line. Although it will be difficult to shake the status of direct charge in smart phone charging for a while, I believe that wireless charging will replace direct charge as the mainstream charging method in the future>, and continuous technical optimization, will bring users a perfect experience. If wireless charging is not a fire now, it is estimated that it is difficult to fire up in the future.
Nevertheless, as technology advances, wireless charging technology is expected to improve and become widespread in the future. But for now, it is more a preference of a specific group than an inevitable choice of mass demand. The two main camps, the Wireless Charging Alliance (A4WP) and PMA, have declared mutual compatibility, which means that future wireless charging devices based on these two standards will be able to be compatible with each other's phones, greatly expanding the deviceThe scope of adaptation. However, there are no details on how to achieve bidirectional compatibility between the two standards. Broadcom chief technology officer Henry-Samueli pointed out that the biggest obstacle to the adoption of wireless charging technology is the inconsistent standards.
This is also an important reason for the current wireless charging technology has not been popularized, at present can only say that this thing can be achieved, but mass production still needs time. As long as wireless charging technology can be more mature in the future, making the charging efficiency become faster, and can achieve the charging function of running while charging, then I believe that wireless charging technology will definitely become a reality in the futureThe preferred configuration technology for new energy vehicles.
1, the basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. 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.
2, the original wireless chargingReason: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the transmitting coil generates a certain current in the mobile phone receiving coil based on the alternating current of a certain frequency through electromagnetic induction, thus transferring the electrical energy from the transmitting end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
3, wireless charging system mainly uses 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, by using the magnetic field generated between the coils, the magical transmission of electrical energyInductive coupling technology will become a bridge connecting charging base stations and devices.

1, Tesla acquired the German WIFERION, in the modified version of the Model 3 application of wireless charging technology, behind the logic is electromagnetic induction wireless charging. The current modified Tesla Model 3 can achieve a maximum of 12KW wireless charging power, the mostIt's 80 kilometers an hour fast, and it could take about six hours to fill up. 2, in fact, the technology of wireless charging, as early as more than a hundred years ago, proposed by the famous electrical engineer Nikola Tesla. Tesla's idea was feasible, but financial and social conditions did not allow it, so it did not succeed. On June 7, 2007, the journal Science published the results of a research team at the Massachusetts Institute of Technology, who successfully realized wireless charging.
3. First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. This technology canA special electromagnetic field transmits energy, allowing Tesla cars to charge themselves when parked. This technology is not only efficient, but can also greatly reduce charging time. Secondly, the wireless charging technology of Tesla cars also has the characteristics of intelligence. 4, the charging process of Tesla takes about 12 hours, but when using a home charger, the voltage may drop due to the peak of the transformer load, which affects the charging speed. To increase efficiency, it is recommended to install a special wall-mounted charger, which will reduce the charging time to about 9 hours. The optional built-in dual charger can further shorten the charging cycle and charge to full
