Description
technical field [0001] The present invention relates to a coil for a wireless energy transmission device. Background technique [0002] Magnetic resonance coupled wireless energy transfer technology is the Massachusetts Institute of Technology (MIT) A breakthrough technology proposed in 2007 by a research team led by an associate professor. This wireless energy transmission method is based on the principle of magnetic field resonance coupling, so that the energy transmitting and receiving coils with the same resonant frequency generate electromagnetic resonance phenomenon under the action of the excitation source (the excitation source frequency is this resonant frequency), so as to realize the efficient transmission of electric energy. In the verification experiment, the MIT research team successfully lit a 60W lamp at a distance of 2m, with an efficiency of about 40%. This wireless energy transmission method can transmit high-power electric energy with high efficiency o...
