Abstract

The invention discloses a coupling coil experiment platform for an electric vehicle wireless charging system. The experiment platform includes: a coupling coil fixing device; a three-axis motion gantry device, the coupling coil fixing device is arranged on the three-axis motion gantry device, the The three-axis motion gantry device can drive the coupling coil fixing device to move in the three-axis direction; the control system selectively controls the movement of the three-axis motion gantry device. As a result, the three-axis motion gantry device can enable the coupling coil to achieve longitudinal travel, lateral offset, and adjustment of the coil spacing, so that the position of the coupling coil can be precisely controlled, and the accuracy of the experimental results can be improved. Moreover, the experimental platform can solve The coupling coil fixing problem can ensure the fixing reliability of the coupling coil, save the platform construction time, and shorten the experiment time.
