Foreigner Object Detect (FO)D) Under normal functional conditions, there is a metal foreign body on the launch end, will not occur heat; Heat occurs when a metal object is placed on the transmitting end and the receiving end is stacked on top. Because the electromagnetic field will generate eddy current on the foreign body of the metal, it will heat the foreign body of the metal, resulting in a dangerous meltdown of the shell.
Identify QI standard: Wireless charging currently has two major international mainstream industry standards. One is the QI standard of the Wireless Charging Alliance (WPC), and the other is the AirFuelAlliance. These two standards for wireless charging products, technical parameters, compatibleThe "System" technology fully integrates a variety of high-performance mixed-signal functions, such as low-power device detection during standby and foreign object detection (FOD) for secure wireless charging. The high level of integration and advanced features help simplify the system design of application engineers, and the periphery is extremely simple, while greatly reducing the difficulty of PCB design.
2, wireless charger refers to the use of electromagnetic wave induction principle for charging equipment, the principle is similar to a transformer. There is a coil in the sending end and the receiving end. The sending end coil is connected to the wired power supply to generate an electromagnetic signal, and the receiving end coil senses the electromagnetic signal at the sending endThis generates a current to charge the battery.
3, 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. 4, wireless charger uses the latest wireless charging technology, through the use of the magnetic field generated between the coils to transmit power, without the wire this medium, inductive coupling technology will become a bridge connecting the charging base station and equipment. Wireless charging system masterThe principle of electromagnetic induction is used, and the energy is transferred through the energy coupling of the coil. 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.
5, durable: the power transmission element is not exposed, so it will not be eroded by moisture and oxygen in the air; There is no contact, so there is no loss caused by mechanical wear and flaring during connection and separation. Convenient: there is no need to connect with wires when charging, as long as it is placed near the charger, there is no need to occupy multiple power sockets, and there is no trouble of multiple wires winding each other.
6, you are normal no-load voltage and low load voltage. The no-load voltage is normal, indicating that your wireless charging transceiver circuit is normal, but the voltage is pulled down after the load, the most likely is that your coil matching is not good, resulting in insufficient power received by the output end, so the charging voltage will be pulled down.
1, the core advantage of wireless charging is that there is no need for cumbersome charging lines, boway wireless charger provides a safe and convenient wireless charging experience for mobile phones5W-5W-10W, compatible with QI-BPP and Samsung fast charge protocol, suitable for Apple, millet and other multi-brand devices. The boway charging pad is designed to be flexible and can be easily charged either vertically or horizontally, while also doubling as a phone stand.
2, boway wireless charger appearance using circular design, unlike other wireless chargers is that the product also has a mobile phone stand function, you can put the phone on the above side charging side use, do not need to frequently pick up and put down. Performance can be compatible with QI wireless reception 5W, 5W and 10W mobile phones, and can intelligently identify mobile phone systems, such as Apple system matching 5w fast charge, Android system matching 10w fast charge.
3, the appearance of Boway wireless charger uses a circular design, and other wireless chargers are different from the product also has a mobile phone stand function, can be used while charging, do not need to frequently pick up and put down. In terms of performance, it is compatible with QI wireless receiving 5W, 5W and 10W mobile phones, and can intelligently identify mobile phone systems, such as Apple system matching 5w fast charge and Android system matching 10w fast charge.
The method of use is as follows: After plugging in the power supply, touch the arc light pole with your finger at any positionLight up after setting. Put the device that needs to be charged under the lamp, switch the mobile phone to the wireless charging mode, and put it into the wireless charging induction area of the lamp. Use the phone charging cable to connect the lamp USB port to the phone, and the phone can also be charged.
Very simple, discharge regularly. For example, every month (if there has been no power failure), do not plug in the AC plug, turn on the light, until the light is not bright, indicating that the electricity has been discharged. Plug in the AC power.
Wireless charging, the desktop has never been so tidy. The touch design is adopted, and the three touch buttons below are the light switch key, the on key and the timing off in turnSwitch. At the same time, this is also the wireless charging area, if your mobile phone supports wireless charging, it can be directly put up to charge the mobile phone, say goodbye to the bondage of the data line, the desktop is suddenly clean. Oh, and you can charge it wirelessly without turning on the lamp.
How to use Huawei wireless charging desk lamp? In addition to the way you can turn on and off by touch, there are more detailed adjustment functions on its panel, with a finger gently swipe, you can adjust the brightness of the light stepless, the experience is exactly the same as adjusting the brightness of the mobile phone, and because this operation does not involve mechanical movement, it will never have wear and agingThe experience is the same no matter how long you use it.
1, wireless charging Qi certification testing content includes Compliance test (Compliance test) and Interoperability Test. The compliance Test was conducted by the Authorized Test Lab (ATL) with 5 samples.
2The compatibility test includes the communication protocol between the transmitter and the receiver, the ability to move on the XYZ axis, the ability to transmit energy, and the detection of foreign objects. Compatibility testing ensures that each QI-certified device and charger works together, supports products from different manufacturers, and is compatible with products under the Qi standard. Products that pass these two tests ensure a safe and reliable wireless charging experience.
3, the main test contents include: 1) the timing of the communication protocol between the transmitter and the receiver; 2) Test the power output capability through the translation of the XYZ axis; 3) Energy transmissionMaximum supply capacity; 4) Foreign Object Detection (FOD). Compatibility testing.
