2.無線充電（Wireless Charging）
Wireless changing is different from inductive charging, and information transmission, such as radio signal。Wireless means transferring power and energy in a great distance.It is typically done through electromagnetic resonance。其實與感應充電相比，其特點就是相隔的距離大了很多，采用的原理也并不相同。
無線充電的SAE標準SAE J2954TIR（technical information reference），有著眾多的參與者，很奇怪這個工作組竟然是BMW來lead的：
有個項目介紹挺詳細的，見參考文獻2，項目預算為$400K，我在網上搜到一個類似的國內項目，不過我一點都不報希望，這位先生只會扯淡，但是預算估計相若。
其結構為，關于天線的照片挺清晰的
