Today to share the knowledge of wireless charging business, which will also explain the commercial wireless charging, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>The use of electromagnetic induction principle for charging equipment, the principle is similar to the transformer, through the transmitter and receiver end set coils, the transmitter coil under the action of power to send electromagnetic signals, the receiver coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
Basic principles of wireless charging,That is, the current is converted 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, 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 is usedTo a business phone? Xiaomi 40W wireless charging is fast, but when will it be applied to commercial mobile phones?
Xiaomi's latest technological breakthrough is undoubtedly a bright one - they demonstrated 40 watts of wireless charging capability, surpassing the 30W "Mi Charge Turbo" of the Xiaomi Mi 10 Pro. This is particularly evident on the unnamed 4000mAh capacity phone, which goes from zero to 57% in 20 minutes and is fully charged after 40 minutes, enough to marvel at its super-fast speed.
Xiaomi 40W wireless fast enrichment test:Xiaomi today officially released its latest 40W wireless fast charging technology, the highlight of this technology is to provide amazing charging speed for 4000mAh batteries. After a field test of Sina's mobile phone, we can find out. The test took place at the Mi Home, where the Sina phone used a specially modified Mi 10 Pro and a Xiaomi vertical wireless fast charging device.
In the recent 5G era charging technology communication meeting, Xiaomi took the lead in demonstrating its 30W wireless flash charging technology, this innovative technology will be the first to be applied in the millet 9 Pro 5G mobile phone, is expected to be released soon.Impressively, the 30W wireless flash charge is able to charge a 4000mAh battery to 50% in just 25 minutes, while a full charge takes only 69 minutes.
Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
Wireless charging, 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 equipment (charger) to transmit energy toAn electrical device that uses the received energy to charge a battery and at the same time for its own operation.Wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the device that uses electricity. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.
Wireless charging means providing electrical power to electronic devices wirelessly. Wireless charging is a modern technology that does not require a traditional physical cable connection for electronic devicesCharge up. The basic principle is to use electromagnetic induction or radio waves to transmit energy. This technology uses a charging dock or charger to wirelessly sense the device to transfer power. There are many ways to implement the specific principles and technologies of wireless charging.
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.
1, the advantages of wireless charging cars are very obvious, such as electric vehicle wireless charging without exposed connectors, so that you can completely avoid leakage, electricity and other safety hazards. At the same time, wireless charging can be used to hide the power supply and transformer underground, so that the car can be charged in the parking place or special charging points on the street. BMW is offering a wireless charging system on its 530e iPerformance hybrid.
2, automobile wireless charging technology is a kind ofThe charging method of electric vehicles that does not rely on charging cables, realizes non-contact power transmission through electromagnetic induction, electromagnetic resonance, radio frequency and other means, and avoids safety hazards such as leakage and electricity running. Compared with traditional wired charging, it has the advantages of convenient use and no supervision, but the power is smaller and the transmission efficiency is slightly lower. Electric vehicle wireless charging mainly has two ways: electromagnetic induction and magnetic resonance.
3, the wireless charging technology of electric vehicles, that is, through electromagnetic induction, magnetic resonance or radio frequency and other ways, to achieve non-contact power transmission without charging cables. This technology avoids the problems of traditional wired chargingAt the same time, the wireless charging system does not need exposed connectors, so it is more adaptable to a variety of harsh environmental and weather conditions.
4, at present, no safety problems have been found in electric vehicle charging piles, nor have they been found to have any adverse effects on the surrounding natural and human settlements. As long as there is no human sabotage or safety accident, there will be no impact on people.
5, slow charge. Slow charging, also known as conventional charging, vehicle charging, is the use of portable charging equipment carried with the car to charge, can use household power and charging pile. This slow charge has a smaller charging currentGenerally, it is about 6A~32A, and the current can be directly used for two-phase AC or three-phase AC.
Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
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 to contact the device that needs to be charged with the wireless charging baseCharge up.

First you need to go to the "Advanced Wireless Settings" page. We can see that the Radio Time Restrictions are disabled by default, but we've changed them to "enabled". Then 24 squares will appear, one for each dayWith green representing wireless on and red representing wireless off, we are free to set The Times of the day when wireless is on and when wireless is off.

(Note: If you cannot enter the management page after entering the press enter, press the reset button for 15 seconds to reset, and then open the browser again and enter the IP address.) After the management page appears, enter the management password, which is usually admin by default. After logging in, you can see three modes: AP mode, trunk mode, and routing mode.
Ensure that the router is working in dual frequency band (dual frequency is 4G, 5G Hertz state), mode: 11bng ixed band bandwidth 40MHz, then open the WIFI setting of the phone, then press the menu key, touch the menu key, go to "Advanced" → "WLAN band", here you can choose → automatic → or only 4G Hertz → or only 5G Hertz band.
Open the browser, enter the management address: 19161, and press Enter to enter the router management interface. If direct access is not possible, try pressing the reset button of the router for 15 seconds, thenThen try to enter the IP address again.
