The invention discloses a high-efficiency wireless electric energy transmission control device for an electric vehicle, and belongs to the technical field of new energy vehicle charging equipment. According to the invention, the problem of low electric energy transmission efficiency caused by short alignment time of a transmitting coil and a receiving coil in a vehicle moving process when the electric vehicle is charged by a dynamic charging mode in the prior art is solved. A first axle shaft is horizontally sleeved on a first transmission rod, the first axle shaft is of a hollow structure, afirst position sensor and a first speed sensor are arranged in the first axle shaft, a transmitting coil is arranged on an inner wall of the plane side of the first axle shaft, a first frequency converter is connected to a first motor, position signals and speed signals received by the first position sensor and the first speed sensor are received through the first frequency converter, the rotatingangle of the first motor is controlled, and then the rotating angle of the transmitting coil on the first axle shaft is controlled. By adjusting the relative positions of the transmitting coil and the receiving coil in real time, a longer alignment time of the transmitting coil and the receiving coil can be ensured.
一种用于电动汽车的高效率无线电能传输控制装置,属于新能源汽车充电设备技术领域。本发明解决了现有的采用动态充电方式为电动车辆充电时,因车辆运动过程中发射线圈与接收线圈对齐时间短,导致电能的传输效率低的问题。第一半轴水平套装在第一传动杆上,第一半轴为空心结构,且其内部装设有第一位置传感器及第一速度传感器,所述发射线圈装设在第一半轴平面侧的内壁,第一变频器与第一电机连接,通过第一变频器接收第一位置传感器及第一速度传感器接收的位置信号及速度信号,控制第一电机的旋转角度,进而控制第一半轴上发射线圈的旋转角度。通过实时调整发射线圈和接收线圈的相对位置,保证发射线圈与接收线圈对齐时间更长。
