基于BP神经网络的线圈定位技术研究
Research on coil positioning technology based on BP neural network
With the improvement of the popularity of electric vehicles in human society, wireless charging of electric vehicles as a more convenient and fast charging method is gradually put into use. In the process of electric vehicle wireless charging, the alignment of transmitting coil and receiving coil is directly related to the charging power and charging efficiency. In this paper, a receiving coil positioning technology based on BP neural network is proposed. The positioning function is realized by establishing a neural network with the induced voltage of detection coil as the input layer and the two-dimensional coordinates of the receiving coil as the output layer. The simulation and experimental verification were carried out successfully. This technology helps to guide the drivers or automatic driving system to align the transmitting coil, which is of positive significance to the development and application of the wireless charging technology for electric vehicles.
