The invention discloses an alignment control method for a wireless charging coil, a device, and an electric vehicle, and belongs to the technical field of electric automobiles. The method comprises following steps: a vehicle end controller sends vehicle alignment instruction to a charging end controller, after receiving the vehicle alignment instruction, the charging end controller controls a charging end power coil to send an electromagnetic pulse, measures the pulse magnetic flux of the electromagnetic pulse, records the pulse magnetic flux as a first pulse magnetic flux, and sends the firstpulse magnetic flux to the vehicle end controller; the vehicle-end controller controls a vehicle end power coil to receive the electromagnetic pulse sent by the charging end power coil, measures thepulse magnetic flux of the received electromagnetic pulse, and records the pulse magnetic flux as second pulse magnetic flux; and the vehicle end controller determines the alignment rate of the wireless charging coil according to the first pulse magnetic flux and the second pulse magnetic flux. Whether the vehicle end power coil and the charging end power coil are aligned or not is directly determined according to the pulse magnetic flux of a transceiving power coil, so that compared with the prior art, the result is more accurate.

    本发明公开了一种无线充电线圈的对准控制方法、装置和电动汽车,属于电动汽车技术领域,车辆端控制器向充电端控制器发送车辆对准指令;充电端控制器在接收到车辆对准指令后控制充电端功率线圈发送电磁脉冲,充电端控制器测量电磁脉冲的脉冲磁通量,记为第一脉冲磁通量,将第一脉冲磁通量发送给车辆端控制器;车辆端控制器控制车辆端功率线圈接收充电端功率线圈发送的电磁脉冲,并测量接收到的电磁脉冲的脉冲磁通量,记为第二脉冲磁通量;车辆端控制器根据第一脉冲磁通量与第二脉冲磁通量确定无线充电线圈的对准率。由于本发明直接根据收发功率线圈的脉冲磁通量来确定车辆端功率线圈与充电端功率线圈是否对准,与现有技术相比结果更准确。
