A high-efficiency wireless power transfer control device for electric vehicles

Abstract

A high-efficiency wireless power transmission control device for electric vehicles belongs to the technical field of new energy vehicle charging equipment. The invention solves the problem of low transmission efficiency of electric energy due to the short alignment time of the transmitting coil and the receiving coil during the movement of the vehicle when the existing dynamic charging method is used to charge the electric vehicle. The first semi-axis is horizontally sleeved on the first transmission rod, the first semi-axis is a hollow structure, and a first position sensor and a first speed sensor are installed inside it, and the transmitting coil is installed on the plane side of the first semi-axis The inner wall of the first inverter is connected to the first motor, and the position signal and speed signal received by the first position sensor and the first speed sensor are received by the first inverter to control the rotation angle of the first motor, and then control the first semi-axis Rotation angle of the upper transmit coil. By adjusting the relative position of the transmitting coil and the receiving coil in real time, it is ensured that the transmitting coil and the receiving coil are aligned for a longer period of time.

Description

technical field [0001] The invention relates to a high-efficiency wireless power transmission control device for electric vehicles, belonging to the technical field of charging equipment for new energy vehicles. Background technique [0002] In the prior art, traditional static wireless charging has the same problems as wired charging for automobiles, such as frequent charging, short cruising range, large battery usage, and high cost. Especially for public transport vehicles such as electric buses. In this context, the dynamic wireless charging technology for electric vehicles has emerged as the times require, which provides real-time energy supply for driving electric vehicles in a non-contact manner. When the dynamic charging method is used in the prior art, the transmitting coil and the receiving coil are two A plane, and the transmitting coil is fixed relative to the ground, and the receiving coil is fixed relative to the vehicle body. When the vehicle is running, the t...
