The first patent application for wireless charging technology can be traced back to 1891, by Nikola Tesla. The core of this technology lies in not having to go through a physical line straightThe connection supplies power to the device, but establishes wireless energy transmission between the charger and the device through the principle of electromagnetic induction or magnetic resonance. Tesla's wireless charging research laid the foundation for later wireless charging technology.
Oh, this invention is indeed an Amway patent! Fulton Innovation, a subsidiary of Amway, launched the world's first wireless charging Tesla car from January 6 to 9, 2011, "2011 International Consumer Electronics Show" was held in Las Vegas, United States. At the exhibition, Fulton Innovation, a subsidiary of Amway Corporation of the United States, demonstrated wireless charging technology and launched the WorldThe world's first Tesla car with wireless charging.
Obviously, wireless charging technology is not limited to the charging of portable electronic products. In fact, as early as 1890, the SerbiAn-American inventor, physicist, and famous scientist Nikola Tesla has done wireless transmission experiments, the first man-made AC power generation.
Mobile phone wireless charging was first invented in Finland in 2012, and there was a similar design before, until the Nokia 920 was launched in 2012, which is the true sense of wireless charging mobile phone.
1, wireless charging mobile phone has wireless fast charge who first : Huawei MateRS wireless fast charge who first , Huawei MateRS Porsche version built-in 4000mAh battery Wireless fast charge who first , support SuperCharge25W super fast charge, it is also Huawei's first mobile phone to support wireless charging, 10W Supported NoneLine charging function.
2, Huawei Mate 60 series, such as Mate 60 and Mate 60 Pro, not only supports wireless charging, but also has efficient wireless fast charging function, such as Mate 60 supports 50W wireless fast charging, which can quickly charge mobile phones in a short time. In addition, the series of mobile phones also support wireless reverse charging, which can be used for other devices that support wireless charging, such as Bluetooth headphones, smart watches and other emergency charging.
3. As of December 12, 2019, HUAWEI has the following mobile phones supporting wireless charging: HUAWEI Mate 30 5G, HUAWEI P30 Pro, HUAWEI Mate 20 Pro (UD), HUAWEI Mate RS Porsche design.
After powering the wireless charger, directly place the phone screen facing up in the center of the charger or the position suggested by the manufacturer to charge.
Insert the charging head into the wireless charger; Then put the phone on it; The best way to place the phone is to put it vertically, so that it can better contactTo the coil at the back of the phone; After the phone is put on, the phone will automatically show the super fast charge 40w.
Place the phone on the charger so that the screen faces up. For best performance, place the phone in the center of the charger or in the location recommended by the manufacturer. The phone should make a "drip" sound after placing it on the wireless charger for a few seconds, indicating the start of charging. When charging starts, you should see the symbol "Fast Charge over Super Fast Charge" in your phone's status bar.
Huawei Mate30 wireless charging does not need to be turned on, you only need to put the phone on the wireless charging board, the phone will automatically enter the chargeAfter Huawei Mate30 is placed on the wireless charger, the screen displays multiple lightning ICONS and the current power, and a line of eye-catching wireless super fast charge words appears below, indicating that 27W super wireless charging is being carried out. The Huawei Mate30 is a mobile phone from Huawei that was launched on September 19, 2019 in Munich, Germany.
Next, under the Settings menu, find and click on [Battery]. Finally, open the switch button on the right side of [wireless reverse charging]. The Huawei Mate30Pro, a smartphone owned by Huawei, is seen on September 19, 2019 in Mueny, GermanyBlack release.
Wireless charger is the use of electromagnetic wave induction to charge, so the current and electromagnetic induction, the phone needs to be turned on. The following describes how to use Huawei Fast Charge wireless charger. First connect the 9V2A charger to the power outlet and connect the data cable. Then connect the USB-C end of the data cable to the wireless charger. Place the charging area of the phone with the plateless cable charging function in the center of the wireless charger's upper surface, and the phone will show that it is charging.
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.
The main principle of wireless charging is the electromagnetic induction principle. It is charged in a non-contact manner, by the charger andA magnetic field is generated between the charged devices to transfer electrical energy. The following explains the principle of wireless charging in detail. Wireless charging technology is mainly based on the principle of electromagnetic induction. Specifically, when the AC magnetic field is generated on the charger, the electric energy is transferred to the device through the action of the magnetic field, and the wireless power supply is realized.
Electromagnetic induction: The fundamental principle is to use the principle of electromagnetic induction, similar to a transformer, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring the energy from the transmission end to the receiving end. The conversion efficiency is high, the cost is cheap, but the transmission distance is short, and it is easy to be placedImpact.
Wireless charging mainly uses electromagnetic induction, magnetic field resonance, radio waves, electric field coupling and other principles. Wireless charging Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
The principle of wireless charging mobile phone is: electromagnetic induction principle, electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger transmission coil) will generate a magnetic field, other unenergized coil (mobile phone end of the coil) close to the magnetic field will generate current, charging for the mobile phone.
