The present invention relates to a method for repositioning a power receiving coil (122) of a vehicle (1) relative a power emitting coil (222) of a wireless charging system (200, 200'). The method comprising the steps of: detecting (S1) a positioning of the vehicle at a charging location (50) in which the power receiving coil detects reception of electromagnetic radiation emitted from the power emitting coil, determining (S2) whether or not the efficiency of the electromagnetic radiation reception of the power receiving coil achieves a pre-set criteria, repositioning (S3) the power receiving coil relative the power emitting coil in at least the vertical direction (z) in response to determining that the efficiency of the electromagnetic radiation reception does not fulfill the pre-set criteria.
本申请涉及一种用于重定位车辆的电力接收线圈的方法,尤其是用于使车辆(1)的电力接收线圈(122)相对于无线充电系统(200、200’)的电力发射线圈(222)重定位的方法。该方法包括以下步骤:‑检测(S1)车辆在充电位置(50)的定位,在该充电位置,电力接收线圈检测对从电力发射线圈发射的电磁辐射的接收,‑确定(S2)电力接收线圈的电磁辐射接收的效率是否达到预设标准,‑响应于确定电磁辐射接收的效率不满足预设标准,至少在竖直方向(z)上使电力接收线圈相对于电力发射线圈重定位(S3)。
