The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. System workWhen 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 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.
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 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.
Generally seen wireless charging, the use of the "current magnetic effect" and "electromagnetic induction" principle. In 1819, the Danish scientist Elster observed that if a piece of wireWith an electric current, a magnetic field will be generated around it, which will deflect the needle. 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."
The principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, in many mobile phones and wireless charger packagesEnd. 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.

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 transmissionIn other ways, wireless charging of mobile phones mostly uses the principle of electromagnetic induction.
If you use vivo mobile phone, you can refer to the following information: wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, you do not need to transfer 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.
Wireless charging is also called inductive charging, non-contact inductive charging,From the wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.

Currently in mobile, electricCars, smart furniture and other fields have appeared to support wireless charging products.

Mobile phone wireless charging technology is completely without the use of wires, the use of magnets for mobile phone charging technology. Mobile phone wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transfer charge in the air between the charger and the mobile phone, coil and capacitor form resonance between the charger and the mobile phone, to achieve efficient transmission of electric energy technology.
Wireless chargerWorking principle: electromagnetic induction principle, energy coupling through the coil to achieve energy transfer.

1, the principle of wireless charging is through near-field induction,The wireless charging device conducts energy to the charging terminal device, which converts the received energy into electricity and stores it in the device's battery. The principle of energy conduction is inductive coupling, which ensures that there is no exposed conductive interface. It can not only eliminate messy transmission lines between devices, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.
2, so now a "closed loop" is formed. Wireless charging power wants to be larger, but the battery will be hot, easy to produce thermal runaway; However, if the wireless charging power is not large, there is no need to get on the car. Unless next, wireless chargingAccess to the tram's thermal management system can be combined with real-time understanding of the state of electric vehicle battery charging, which must take into account algorithms, communication and other aspects.
