Wireless charging will replace the data line charging in the future, which means that there is no data line in the future? This statement is a bit difficult to implement, because the data line is not only simple to charge, but also a function is to transfer data, so wireless charging to completely replace the data line is not reliable, unless the wireless charger also has the function of transmitting data. Otherwise, it is impossible to replace the data line!
After Apple’s recent release of the new iPhone to support Qi charging, the long-awaited wireless charging market seems to be really erupting. For a time, including chips, coils, and upstream and downstream manufacturers in the industry chain have all entered this market. While some companies are gearing up, there are some manufacturers who have been working for many years and are ready to go.
According to public information, Apple’s wireless charging technology used on new phones is the Qi wireless standard that supports the WPC Alliance. This is a wireless charging standard developed and promoted by the WPC Alliance. In this alliance, more than 200 globally renowned companies including Nokia, HTC, LG, Sony, Samsung, Qualcomm and Apple are gathered.
It now appears that the Qi standard promoted by WPC is undoubtedly the first choice for wireless charging. But looking back at the development of wireless charging, there was competition for WPC, A4WP and PMA in the early stage; later it evolved into WPC and Airfuel (Airfuel merged from A4WP and PMA). The reason why WPC can break through is mainly related to its versatility and compatibility. In addition to its high efficiency, safety and large volume, the Qi standard is almost the choice of all manufacturers.
As the mainstream wireless charging standard in the industry, the WPC Alliance initially promoted magnetic induction wireless charging, but after Qi 1.2, they incorporated magnetic resonance technology and added support for multi-device charging. According to the WPC, the introduction of magnetic resonance is mainly due to two points: one is to provide more space freedom for low-power products (mainly longitudinal distance), and the other is to provide more power. At this point, wireless charging has the potential to break out.
After understanding its development and principles, the practical application of Qi standard wireless charging requires the receiver and transmitter to achieve wireless charging. When the mobile phone equipped with the receiving end is placed above the charging platform of the body, the device will generate voltage through the electromagnetic induction to directly charge the mobile phone or the battery.
However, wireless charging will be a trend, and more products will be used later! So the future of wireless charging is great.
