Adopt the mode of independent power supply, just supply power to the coil of below to the automobile body when normal work, this kind of sectional type power supply mode not only can reduce system's loss, but also can effectively reduce the electromagnetism and reveal.
However, during the driving of the electric vehicle, the coupling coefficient between the transmitting coil and the receiving coil can change rapidly in a wide range, and the transmission power and efficiency of the system can be greatly reduced. The wide variation of the coupling coefficient can also cause the transmission power of the system to generate huge fluctuation, and the reliability of the system is reduced.
