摘要
The continuous development of wireless power transmission technology provides a reliable way to charge electric vehicles. To ensure the performance of power transmission, it's essential to ensure that the transmitter coil and the receiver coil of the electric vehicle are correctly aligned. In this paper, a localization method based on three sector-shaped auxiliary coils, which have the same structure, is proposed to determine the current position of the vehicle by detecting the coupling between the auxiliary coils and the receiving coil. The lateral misalignment coefficient (Lm) and bias factor (BF) are defined as the determination conditions of direction and position. A system model is constructed, and the simulation results show that the feasibility of the method is verified in the range of 1.4 times the charging coil diameter.
