The invention provides a wireless charging system guiding and aligning method and a vehicle, and belongs to the field of wireless charging equipment. The wireless charging system comprises a charging transmitting coil connected with a charging power supply in the ground transmitting equipment, a charging receiving coil connected with a vehicle power battery in the vehicle receiving equipment, a transmitting coil in the ground transmitting equipment and a receiving coil in the vehicle receiving equipment. The transmitting coil generates an alternating identification magnetic field covering the charging transmitting coil, and the intensity of the identification magnetic field spatially changes along with the change of the distance to the central position of the charging transmitting coil. And a plurality of receiving coils are arranged around the central position of the charging receiving coil, or one receiving coil is arranged in the middle of the charging receiving coil and is used for inducing the identification magnetic field to generate induced electromotive force. And the induced electromotive force of the optimal charging position is calibrated and compared with the induced electromotive force intensity of the receiving coil detected in real time, and the relative position relation between the ground end equipment and the vehicle-mounted end equipment is deduced.
本发明提供了一种无线充电系统引导与对位方法及车辆,属于无线充电设备领域。无线充电系统包括地面发射设备中与充电电源相连的充电发射线圈、车辆接收设备中与车辆动力电池相连的充电接收线圈、地面发射设备中的发射线圈和车辆接收设备中的接收线圈。发射线圈产生覆盖充电发射线圈的交变的识别磁场,识别磁场的强度在空间上随着到充电发射线圈中心位置的距离变化而变化。接收线圈有多个,围绕充电接收线圈中心位置排列,或者,接收线圈有1个,设置在充电接收线圈中间,用于感应所述识别磁场生成感应电动势。标定最佳充电位置的感应电动势并与实时检测到的接收线圈的感应电动势强度相比较,推断地面端设备与车载端设备的相对位置关系。
