This article to talk about mobile phone wireless charging technology, as well as mobile phone wireless charging technology corresponding knowledge points, I hope to help you, don't forget to collect this site oh. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Why was the wireless charging of mobile phones that was praised to the sky, but now it is rarely seen around people using it? _ Baidu Know...
1, due to the heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging. After all, wired fast charge has developed to 120W, and the fast charge carried by most mobile phones is more than 60W, which has surpassed the wireless fast charge, so wireless charging has gradually opened the gap with wired fast charge because of the technical requirements of the equipment.
2, chargePower limited, charging technology is not interworking between different brands of mobile phone power update quickly, a day to improve a power, from the original 18W fast charge into a variety of fast charge power, 30W, 45W, 65W, and now there are 120W super fast charge power, which also leads to the current world of wireless charging board a lot of very complicated, If you choose the wrong one, you will not experience the full charging power. 3, because there is a heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, so in 2021, the Ministry of Industry and Information Technology of China issued a policy againstWireless charging equipment technical requirements, which have clear provisions: wireless charging rated power shall not exceed 50W. In order to comply with this regulation, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging.
4, that is, the power of the universal charge is particularly large, many people who have used the universal charge know that their mobile phone battery is more and more charged, the more and less power is charged, originally full of 100% can be used for two hours, but to the back, it may only be used for half an hour.
5, currently does not support long-distance charging. In theory, wireless chargingElectrical technology is safe and harmless to the human body, the resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, the magnetic field used by wireless charging technology is itself harmless to the human body.
There are many mobile phones that support wireless charging, mainly including the following categories: Apple series mobile phones Since the launch of the iPhone, some high-end models support wireless charging. Such as the iPhone XS,The iPhone XR, iPhone 11 and iPhone 12 all support wireless charging technology. Apple's own AirPods wireless chargers also work with these phones.
Apple iPhone series: Starting with the iPhone 8 series, Apple has supported wireless charging. Subsequent iPhone models, such as the iPhone XS, iPhone XR and iPhone 11 series, also have built-in wireless charging capabilities. Huawei/Honor series phones: Huawei and Honor have many mid - and high-end phonesWith wireless charging technology.
Huawei supports the following mobile phone models for wireless charging: For example, Huawei p40pro and Huawei p30pro. Huawei mate30rs, Huawei mate30pro5g, etc. Samsung supports wireless charging mobile phone models as follows: S6NoteS6Duos, etc. Now most smart phones can support mobile phone wireless chargers.
Wireless charging mobile phones include but are not limited to the following: Samsung Galaxy series supports wireless charging, including the latest Samsung S21 series, which supports wireless charging technologyM. The Mi MIX2S is one of the phones that supports wireless charging, featuring a glass and ceramic body design, a 99-inch 1080P full HD LECD screen and a Qualcomm Snapdragon 845 processor with 5W wireless charging power.
Apple: The iphone supports wireless charging models are iPhoneX series, iPhone11 series, iPhone12 series, iPhone13 series, and the second generation and later versions of iPhone. All of Apple's phones have an induction coil on the back and can use wireless? '> What dark technology is wireless charging? Small whale cloud wireless charging is how to do?
The small whale Cloud wireless charging device uses low-frequency magnetic resonance technology, and the maximum effective charging distance can reach 3CM. When in use, the wireless charging transmitter is placed under the desktop (the desktop cannot be made of metal or magnetic conductive material), and the wireless charging can be carried out when the mobile phone with wireless function is placed on the desktop sticker.
Need to mention a point is its black technology face recognition (optional). What is this function? As a simple example, the dashboard will have a camera on it when you compareWith a gesture (OK gesture), you can switch the driving mode to track mode, which is very interesting.
This is the end of the introduction of mobile phone wireless charging technology and mobile phone wireless charging technology. Do you know if you can find the information you need? If you want to know more about this, remember to follow this site. < / p >
