Abstract

The invention discloses a three-phase decoupling transmitting and receiving coil structure for wireless charging of an electric vehicle. The three-phase decoupling transmitting and receiving coil structure comprises three transmitting coils and a receiving coil, wherein the three transmitting coils are rectangular and are respectively a transmitting coil A, a transmitting coil B and a transmitting coil C; and the rectangular plane of the receiving coil and the rectangular plane of the transmitting coil are parallel to each other and are spaced by a certain distance. By adopting the technical scheme, the problem of low energy transmission efficiency of the existing wireless charging system of the electric vehicle is solved, and high-efficiency energy transmission can be kept under the condition that the center of the receiving coil and the center of the transmitting coil have large deviation.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle battery charging, in particular to wireless charging technology. More specifically, the present invention relates to a three-phase decoupled transmitting and receiving coil structure for electric vehicle wireless charging. Background technique [0002] At the time when the short battery life and difficult charging of new energy vehicles still plague the entire new energy vehicle industry, the application of wireless charging technology in new energy vehicles has attracted more and more attention. Among the common radio transmission methods on the market, electromagnetic induction is the mainstream technology, but the current system transmission efficiency is generally low, which cannot meet the requirements of batch applications. [0003] Among the many factors affecting the transmission efficiency, the design of the transmitting coil located in the transmitting module and the receiving ...
