About Wireless charging standard

When we talk about wireless charging standard, there is no uniform so far, totally there are five different kinds for wireless charging:

I.Qi Qi is the world's first wireless charging technology standardization organization introduced by the Wireless Power Consortium (Wireless Power Consortium, referred to as WPC) "wireless charging" standard, with the two characteristics of convenience and versatility. First of all, different brands of products, as long as there is a Qi logo, you can use Qi wireless charger. However, at present, QI's wireless charging technology only stays in the low-power 5CM touch-sensitive mobile phones and other digital products, is currently studying Qualcomm's magnetic resonance technology, mature products from 15W to mid-power watts forward.

2 The PMA Power Matters Alliance standard was launched by Duracell Powermat, a joint venture between P & G and Powermat, a wireless power technology company, with superior overall capabilities. At present, P & G, Powermat, AT & T, Google, Starbucks, BlackBerry and ZTE Samsung and LG also announced their participation in 2013. Earlier products include a U-disk-based wireless charging application based on a mobile phone. The two major wireless charging standards bodies, the Power Matters Alliance (PMA) and the Alliance for Wireless Power (A4WP), have officially announced in 2015 that the combined coalition will be renamed the AirFuel Alliance.

3 A4WP A4WP is an abbreviation of the Alliance for Wireless Power standard and was created by the Wireless Charging Consortium, a joint venture between Qualcomm, Samsung of South Korea and Powermat, mentioned earlier. The consortium also includes members such as Ever Win Industries, Gill Industries, Peiker Acustic and SK Telecom, with the goal of setting technical standards and industry dialogue mechanisms for wireless charging devices for electronic products, including portable electronics and electric vehicles. At present, more than 5CM multi-cell phone at the same time wireless charging and wireless charging products launched.

4 Apple (APPALE) Apple and the end of 2012 to apply for their own wireless charging patent. Apple's wireless charging will establish an effective area of 1 meter charging area by "Near Field Magnetic Resonance" technology. Any Apple device that supports this technology can be wirelessly charged as long as it is placed in the area without any connecting wires or Power plug. This is a hidden monster, but due to delays in the application of technology can not mature breakthrough, the recent IPHONE8 also forced to use QI standard first listing.

5. Love code core (XQI) CN-IMX is one of the largest number of non-standard wireless charging researchers in China. The company started researching non-standard wireless charging in 2009 and proposed in 2010 to standardize its own wireless charging of mobile phone batteries , To avoid the global mobile phone batteries due to non-standard duplication of waste, and hope that the new smart phones using a unified code technology XQI love the standard, the standard battery to solve the global wireless charging is the use of hollow copper coil (including Massachusetts MIT) and can not be together with the metal body ultra-thin wireless charging problem, then developed the same as the original capacity of the same nondestructive thin wireless rechargeable battery, the first invented the use of FPC instead of traditional multi-stranded coil receiver, with ultra-thin Magnetically deintercalating magnetically permeable material completely solves the problem of low eddy current heating efficiency of metal batteries.
