Even if the 20W mobile phone wireless charging, charge oneAfter a period of time, the charging board and the mobile phone backplane (battery) will also have different levels of hot reaction; Applied to electric vehicles, similarly, the battery of electric vehicles will also be hot because of the heat generated, as mentioned above, the greater the power, the easier it is to heat. So now a "closed loop" is formed.
At present, the closest thing to our lives is to support wireless charging of smart phones, and its principle is the same as the basic principle of wireless charging of cars, mainly using electromagnetic induction and magnetic resonance mode to transfer electricity, and these two ways actually have advantages and disadvantages.
Wireless charging technology is a specialAfter transmission through the air, it is converted into current and 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, wireless charging is also known as inductive charging, non-contact inductive charging, from 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 batteryAnd at the same time for its own operational purposes.
3, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, 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.
1. NoneThe line 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.
2, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and converted into a current to be transmitted to the intelligent terminal.

4, there is 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 transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction.
5, wireless charging is 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.

Conclusion Wireless charging inside structure : Millet vertical air-cooled wireless charging with its small size, large output characteristics, become wireless charging inside structure > Wireless charging inside the structure My recent purchase highlights. The following is an intuitive introduction to this product: Unpacking experience: / Millet vertical air-cooled wireless charging 30W in white transparent plastic packaging, visible at a glance. Its simple and generous orange-red packaging box contains the main body, data cable, charging head and instructions, reflecting the wireless charging inside structure Xiaomi's consistent efficient style.
Compared with the common 10W wireless charging technology on the market, Xiaomi's 30W wireless flash charge can charge a 4000mAh battery in 25 minutesIn half of the electricity, to achieve "wireless beyond wired" efficiency. Xiaomi's vertical air-cooled wireless charge 30W is cleverly designed with an ergonomic tilt, which is convenient for users to operate while charging, and the built-in ultra-quiet fan can effectively actively dissipate heat, improving the comfort of the charging process.
Among them, Xiaomi released the vertical air-cooled wireless charge 30W, with its power output of up to 30W, breaking the limitations of traditional wireless charging. It follows the Qi charging standard and is highly compatible, regardless of whether your device supports it or not, it can be easily handled.
