In China, Beijing is studying the use of wireless charging systems on some micro-circulation buses. Wireless charging technology is about to be introduced in places like Zhengzhou and Yunnan, and wireless charging operation lines have been opened in Chengdu, Fuyang and other places.


The history of wireless charging goes back to 1901. Nicholas & dot; Tesla established a wireless charging tower in New York on Long Island, the Wadden Cliff Tower, for wireless transmission trials, although the project ended in failure.


A century later, the research on wireless charging ushered in new sources of power. The range of applications is also very wide – from small electric toothbrushes, remote controls, smart phones, to electric cars and oil rigs. Industry giants Toyota, Nissan, Volvo, Intel and Samsung all joined the ranks of R&D. In China, Beijing is studying the use of wireless charging systems on some micro-circulation buses. Wireless charging technology is about to be introduced in places like Zhengzhou and Yunnan, and wireless charging operation lines have been opened in Chengdu, Fuyang and other places.


1, wireless charging in the end what is the situation, how to achieve wireless charging?


Wireless charging is how it works, as its name suggests is not charging charging line. Similar to WiFi, it is very convenient. In theory, power can be supplied to mobile phones and other electronic devices anytime and anywhere.


However, wireless charging is still not able to transmit as far away as WiFi, and now mature solutions can only achieve wireless charging within a distance of 10mm, generally a distance of about 3~5mm is better, such wireless charging technology is used Magnetic induction wireless charging technology.


In 2015, mass-produced magnetic resonance wireless charging technology is expected to realize wireless charging in a range of around 125px.


With the maturity of technology, it is expected that in the next 2 to 3 years, the charging distance of wireless charging can reach about 10~750px, which can basically meet the charging requirements that are not bound by anytime and anywhere.


To achieve wireless charging requires a transmitter and a receiver.


The transmitter is a wireless charger and the receiver is a mobile phone. There is a coil at the transmitter and a coil at the receiver. The transmitting end transmits energy through the control board and the coil, and the receiving end receives energy through the control board and the coil, so that wireless charging can be realized.


2. Why do I need wireless charging?


The wireless charging first has a few big advantages over the traditional wired charging. You have to choose its advantages:


1, no winding, simple and beautiful, looks comfortable, higher quality of life;


2, do not often plug, put it that charge, convenient and quick, so that your mobile phone will never lack of electricity;


3, do not have to worry about Samsung and Apple connector incompatibility, support Qi and other standard wireless charger can be charged;


4. There is no risk of electrocution of the incoming and outgoing calls, completely avoiding security problems, and can answer the phone at any time;


5, let the battery work longer life, due to the immediate release, so that the battery does not lack of electricity, the battery life is longer.


6, do not need wired interface, many products can be made fully enclosed waterproof products.
