Coupling coil experimental platform for electric vehicle wireless charging system

Abstract

The invention discloses a coupling coil experimental platform for an electric vehicle wireless charging system. The experimental platform comprises a coupling coil fixing device; a three-axis motion gantry device, wherein the coupling coil fixing device is arranged on the three-axis motion gantry device, and the three-axis motion gantry device can drive the coupling coil fixing device to move in athree-axis direction; and a control system, wherein the control system selectively controls the three-axis motion gantry device to move. Therefore, the three-axis motion gantry device can realize thelongitudinal travel, the lateral offset and the coil spacing adjustment of a coupling coil, so that the position of the coupling coil can be accurately controlled, the accuracy of an experimental result can be improved, and the experimental platform can solve the problem of fixing the coupling coil, the fixing reliability of the coupling coil can be ensured, the platform construction time can besaved and the experimental time can be shortened.

Problems solved by technology

Most of the experimental research on wireless charging is to fix the coupling coil through a temporary and simple platform, and to conduct experiments by manually adjusting the position of the coupling coil, which not only increases the preparation time for each experiment, but also manually adjusts the coupling The accuracy and repeatability of the coil position relationship are poor, and the dynamic test of the working performance of the wireless charging system will become difficult or the test effect will be poor
