D: 1.Higher equipment investment, maintenance costs. 2.Higher energy consumption. 3.Big electromagnetic space loss rate.
Prospection
Now, the wireless charging technology in the small power within the scope of the can still shows its superiority.But implementation of high power wireless transmission, it was more difficult.Although now wireless charging whether in the theory and technology in there are many problems, but the progress of science and technology will eventually solve them, global wireless charging is not a distant dream, ultimately, in the near future can be realized.
Use of physics "resonance" （ 共 振 ） principle--two vibration frequency of the same objects can be efficient transport energy Fujitsu （ 富 士 通 ） wireless charging technology used magnetic resonance in charger and equipment in the air between the transmission charge ， Coil and capacitor in charger is formed between and equipment resonance。（线圈和电容 器则在充电器与设备之间形成共鸣）
Background
1. Nikola Tesla , 1891, large "Tesla coil"
2. Professor XuShuYua, in recent years, developed "wireless battery platfoljacic, 2007, lit up a lamp that 60 watt light bulb between two meters
Wireless charging , charge at anytime and anywhere where there has a set (WiTricity) to send the charge, maybe just like the wifi.
Working principle
Wireless energy conversion, the transmission：
4. Several companies have a wireless charging mobile phone production, mp3, portable computers （Portable Mat、 Energizer）

Present situation
1. Wireless Power Consortium(无线充电联 盟), 2008,12,17 2. Internarional Qi Standard took the first lead in introducing BeiJing China 3. Wireless charging technology USES unified industrial standard. 4. Various of the new wireless charging equipments have started to put into application 5.
Application
Advantages and disadvantages
A: 1.Device invisible,low wear rate. 2.High technical content, easy to operate. 3.public charging area relative decrease.
