The invention discloses a wireless charging alignment detection method and device and a storage medium, and the method comprises the steps: obtaining the charging attribute information of a vehicle under the condition that the vehicle is detected to enter a preset mutual inductance value detection region; detecting mutual inductance values between the transmitting coil and the receiving coil at different moments when the vehicle moves in the mutual inductance value detection area; calling a fitting function coefficient set A corresponding to the charging attribute information, and performing curve fitting on the detected mutual inductance values at different moments to obtain a fitting function coefficient array B; matching the B with the A; and under the condition of successful matching, acquiring the relative position between the transmitting coil and the receiving coil corresponding to the mutual inductance value at the stop moment of the vehicle. According to the scheme, high-precision alignment detection of the relative positions of the transmitting coil and the receiving coil is realized without depending on additional devices of wireless charging equipment, and a reference basis is provided for wireless charging starting and high-efficiency control.

    本申请公开了一种无线充电对齐检测方法、设备及存储介质,该方法包括:在检测到车辆进入预设的互感值检测区域的情况下,获取车辆的充电属性信息;检测车辆在互感值检测区域移动过程中不同时刻的发射线圈与接收线圈之间的互感值;调用与充电属性信息对应的拟合函数系数集合A,并将检测得到的不同时刻的互感值进行曲线拟合,得到拟合函数系数阵列B;将B与A进行匹配;在匹配成功的情况下,获取车辆停止时刻的互感值对应的发射线圈与接收线圈之间的相对位置。本方案在不依赖于无线充电设备额外增加器件的情况下,实现发射线圈、接收线圈的相对位置高精度对齐检测,为无线充电启动及高效能控制提供基准依据。
