Far away Wireless charge to increase the distance The electricity is very weak, does not work. Like the induction cooker, the pot will not heat up if it is far away. Verdict: Apple's iPhone 8 is highly likely to support wireless charging technology, which is further confirmed by the latest addition of supplier Lite-On Semiconductor. Lite-On will provide the rectifier for the iPhone 8's wireless charging component, showing how serious Apple is about wireless charging.
Qi wireless charging standard provisionsThe effective charging distance is within 10mm, which is mainly to avoid the impact of electromagnetic radiation on the human body. However, friends who have really used wireless charging in the early years believe that they still remember that the real charging distance is much lower than this, and the specific performance is to accidentally wear a set to the love machine, and wireless charging immediately GG.
Support. The iPhone 8 will support "ultra-long range" wireless charging technology that is more powerful than existing wireless charging, and the phone does not need to be placed on the charging pad while charging. Jianxing Electronics will supply Apple with bridge rectifiers, which work to ensure the efficiency of wireless transmission. Macotakara cited noneAccording to the Cable Charging Alliance (WPC), Apple did not use the 15-watt Qi x fast charge standard this time.
1, Shengshi wireless charging technology hidden wireless charger A new powerful and stable wireless charger, hidden under the desktop, through the desktop for mobile devices to charge. - Extremely stable charging will not be powered off until fully charged. - Charging the future A new powerful wireless charger, hidden inBelow the desktop, charge your mobile device through the desktop. 2. U.S. wireless power provider Ossia, along with companies such as Energous and Powercast, is reportedly planning to launch the service in Japan in 2021. Ossia's innovation lies in space-transmitted radio technology, which envisions sending waves to terminal devices for charging via a transmitter similar to a ceiling light mounted on the ceiling, which is simple and convenient to operate.
3, wireless charging on the market at present belongs to near-field magnetic coupling wireless energy transmission, with the help of the invisible medium in spaceThe magnetic field realizes the energy transfer between the power supply and the electrical equipment. This method is considered harmless to humans, but it must be done in close proximity.
4, not practical. PS: Wireless charging technology is completely without the use of wires, the use of magnets to charge the device technology. Wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transmit charge in the air between the charger and the device, and the coil and capacitor form resonance between the charger and the device to achieve efficient transmission of electric energy technology. The Nokia 920 uses wireless charging as follows for long-distance (about 4 meters) charging Apple is developing.
By enhancing the transmission power between the transmitter and the receiver, Huawei's patent not only improves the charging distance, but also demonstrates the significant improvement of wireless charging technology in practical applications. The following is an example of the application of the patent, showing its potential and advantages in different scenarios.
The key to the patented technology is to enhance the equivalent coupling capacitance between the transmitting electrode and the receiving electrode, which makes the wireless charging transmission distance significantly improved, greatlyIncreased charging flexibility. In this way, even at a relatively long distance, Huawei's wireless charging system can ensure stable transmission power, providing a convenient wireless charging experience for smart wearable devices.
According to reports, Huawei filed a patent application this month for a variety of advanced systems inside the smart car, from the optimization of key access control to vehicle positioning wireless charging equipment, all show its pursuit of the smart car ecosystem precision design. These moves are clearly in line with Huawei's strategy to accelerate its entry into the automotive industry, especially targeting the 5G-powered smart car market.
And now wireless charging to increase the distance , Japanese media brought wireless charging to increase the distance more exciting news: A remote charging technology based on radio waves, similar to Wi-Fi, is moving toward practical use in Japan, powering devices such as robots, electronic price tags and smartphones from up to 10 meters away. According to reports, the US wireless power supply company Ossia, and Energous and Powercast, among others, plan to launch the service in Japan in 2021.
New breakthrough in wireless charging technology: Convenient charging from 10 meters away Wireless charging has become a common way of charging in daily life, but its scope is usually limited to the vicinity of the device. However, Japanese media recently reported that a new wireless charging technology is gradually moving towards practical use in Japan, which breaks the traditional limitations and can provide power for robots, electronic price tags and smart phones from 10 meters away through a similar principle to Wi-Fi waves.
In the wireless charging areaThere is a strong electromagnetic field energy, add some coils here, you will induction voltage. The induced voltage can be converted into the energy received by the cell phone battery. Now, the wireless chargers on the market, it is the use of electromagnetic induction technology. This technology uses the induced magnetic flux generated by the inductive magnet between the mobile phone and the wireless charger.
Generally around 0.9-2 meters high-power wireless charging Wireless charging increase distance Transmission distance up to 5 meters Wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction type wireless charging to increase the distance , such as charging mobile phones wireless charging to increase the distance Qi mode wireless charging to increase the distance , But ZTE's electric car wireless charging method uses inductive mode.
Huawei Mate 30 seriesWith wireless charging Wireless charging to increase the distance , the maximum supported wireless charging power is 27W. Specifically, the Huawei SuperCharge wireless charger that supports Mate 30 series wireless charging has a maximum output power of 27W, which can provide a fast wireless charging experience for Mate 30 series mobile phones.
The iphone14pro wireless charging power is up to 15W, and MagSafe wireless charging technology is used to achieve fast wireless charging and the alignment between the product and the charger is more convenient and accurate.At the same time, the technology has a built-in security chip to ensure charging security and data privacy.
The distance is greater than 10 cm, and the conversion efficiency is only about 60%, that is, the sent power is 1000W, and the received power is only 600W.
At present, the charging distance of magnetic resonance is about 5~10cm, and the charging distance of electromagnetic wave is about 10 m, in short, the farther the charging distance, the lower the charging efficiency. If you want to take into account the longer charging distance and higher charging efficiency, you can only increase the charging power, but this will be harmful to human health. Low energy conversion: wireless charging of the turnThe conversion rate is generally about 70%.
Currently known reports, the farthest distance is 10 meters, using electromagnetic wave technology. The existing wireless charging technology uses magnetic field, electromagnetic wave, laser, ultrasonic and other energy transfer media. The 10-meter technology mentioned above, which uses electromagnetic waves as a medium, remains in the laboratory stage. At present, the commercial technology on the market is mainly magnetic field as the medium, which is divided into magnetic induction and magnetic resonance 2 technologies.
