Wireless charging development (Key technologies of wireless charging)

Wireless charging principle and transmission mode

Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.

Electric vehicle wireless charging technology mainly uses the mutual inductance in the law of electromagnetic induction. Also similar to a transformer, input from the primary coilThen an induced current is generated on the secondary coil. It mainly relies on the energy transmission between electricity and electricity, converts electricity into magnetism, and then induces electricity. Wireless charging is simply to charge electrical equipment through electromagnetic fields or electromagnetic waves without being connected by physical wires.

Wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.

Wireless charging baseThe principle is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and then 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.

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 type wireless charging, when the power supply of electricity circulationThe overcoil (the power supply coil of the wireless charger) will generate a magnetic field, and other unenergized coils (the power supply coil of the mobile phone) will generate current when they are close to the magnetic field, charging the mobile phone. As shown below.

Find a simple mobile phone wireless charger circuit diagram or schematic diagram and schematic analysis

1, electromagnetic induction primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end.

2, the above is the originalThe principle used is the principle of electromagnetic induction.

3, wireless charging technology is the use of electromagnetic induction principle, in the sending and receiving end with the corresponding coil to send and receive inductive current to charge.

4, the so-called wireless charging technology only uses the electromagnetic wave induction principle, and the related AC induction technology, at the sending and receiving end with the corresponding coil to send and receive inductive AC signals to charge. Nothing high-tech, just magnetic fields! The charger has a coil, the battery has a coil, put close to form a kind of transformerWireless charging technology: a new experience of magic and convenient charging

This article will reveal the magic behind wireless charging, take you to enjoy the new experience of convenient charging. Plug-in charging base Wireless charging base actually needs to be plugged in! But don't worry, that doesn't make it any less amazing. Magnetic field transfer energy Wireless charging technology uses magnetic field to transfer energy, from small power electromagnetic induction type to high-power resonance type, completely abandoning cumbersome wire connections.

Conclusion: iPhone8 wireless charging, unlock convenient life iPhone8 wireless charging technology not only meets the consumerThe pursuit of battery life and convenience also predicts the future of mobile phone charging methods. With the implementation of this feature, the mobile phone experience will be more seamless, let's look forward to this revolutionary change.

Turn on Battery options Find the battery options in the Settings menu, turn on and find the wireless reverse charging switch. Turn on wireless reverse charging. Place the screen of your Huawei phone upside down on the desktop with the back facing up. Place the other mobile phone that supports wireless charging on the Huawei mobile phone in a glyph position with the back facing down. Multiple device charging At this point, you should see a reminder that it is charging.
