1, the principle of wireless charging is that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device converts the received energy into electrical energy and stores it in the battery of the device. The principle of energy conduction is inductive coupling, which can ensure that there is no externalThe conductive interface of dew. It can not only eliminate messy transmission lines between devices, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.
2, the popularity and application of wireless charging technology Wireless charging with its convenient and environmental characteristics has gradually become a new trend of mobile phone charging. Through the principle of electromagnetic induction, such as the Qi standard and the PMA standard, the phone can automatically receive energy without physical contact with the charging line.
3. In addition, with the development of wireless charging technology, some wireless charging bases similar to charging bowls begin to appear. This year's Apple Fall eventAirPower on the PPT is a similar device, which can charge multiple devices such as iPhone, Apple Watch, and Air Pods at the same time, and the convenience has skyrocketed. In addition, if wireless charging technology can be popularized, the charging experience in public places will be greatly improved in the future. 4, wireless charging technology has not been widely popular reasons are: the number of terminals less two years ago Nokia Lumia 920 built-in Qi wireless charging technology, and randomly equipped with wireless charging board, but there is no other subsequent factoryBusiness follow up. Although some third-party manufacturers have also launched wireless charging accessories, but need to install a special shell, it is not compatible with other digital devices, the use of inconvenient form.
5, the only way to popularize: universal standards and mobile phone manufacturers support the formation of universal standards is undoubtedly long and tedious, but it is the only way for wireless charging technology. Most importantly, they need the backing of a mobile phone giant such as Apple or Samsung to become widely available. Imagine if Apple's iPhone line started to support some kind of standard wireless charging technology, popularization obviously is not far away.
In general, wireless fast charging is a wireless charging method based on magnetic resonance, electromagnetic induction and other technologies, which eliminates the tedious operation of wired charging and brings more convenient and efficient charging to usersThe electric experience. Its wide application and continuous technological development indicate that wireless fast charging will become the mainstream way of charging electronic devices in the future.
Wireless fast charging is a combination of wireless charging technology and fast charging technology, and the mainstream models on the market now support wireless fast charging technology. Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology 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.
Wireless fast charging is the useElectromagnetic induction principle, there is a coil in the sending and receiving end, the sending end of the coil connected to the wired power supply to generate electromagnetic signal, the receiving end of the coil induction electromagnetic signal to generate current to charge the battery, can be simply understood as a transformer without a magnetic core. Compared with wired, wireless charging has less loss to the battery, and wireless charging technology is more convenient and has lower charging heat.
3, the release of Mi 9 Pro 5G is imminent, one of the highlights of this new product is its revolutionary triple fast charge technology /, including 40W wired super flash charge, 30W wireless super flash charge and 10W reverse wireless charge, designed to provide a full range of charging solutions. First of all, 40W wired super flash charge/is the super flagship standard, equipped with 4000mAh battery, which can be fully charged in only 48 minutes, showing the strength of efficient charging.4, Millet MIX 5G concept mobile phone as a new member, is expected to carry a series of breakthrough technologies, including wide-area screen fingerprint unlock, under the screen camera, 100W super flash charge and 40W super wireless flash charge, which indicates that the mobile phone experience will have a significant improvement.
