The invention discloses an electric vehicle wireless charging interoperability judgment method and system, and relates to an electric vehicle wireless charging monitoring method and device. The invention relates to a wireless charging interoperability judgment method and system for an electric vehicle, and aims to solve the problem of low judgment accuracy of an impedance tolerant region in an existing wireless charging interoperability judgment method or system for the electric vehicle. The wireless charging interoperability judgment method and system for the electric vehicle comprises the following steps: step 1, when a transmitting coil of a wireless charging transmitting end of the electric vehicle is matched with a receiving coil of a wireless charging receiving end of the electric vehicle for charging; obtaining the impedance ZGA of the transmitting coil; 2, importing the value of the ZGA into a preset impedance diagram; 3, detecting whether the value of the impedance ZGA is located in a completely interoperable area or a tolerable interoperable area of the impedance diagram; if yes, it is judged that the electric vehicle wireless charging transmitting end and the electric vehicle wireless charging receiving end can be operated mutually; and otherwise, judging that the wireless charging transmitting end of the electric vehicle and the wireless charging receiving end of the electric vehicle are not interoperable.

    电动汽车无线充电互操作性判定方法及系统,涉及电动汽车无线充电监测方法和装置。目的是为了克服现有用于电动汽车无线充电互操作性判定方法或系统中阻抗容忍区域判定准确性低的问题,其中步骤如下:步骤一、当电动汽车无线充电发射端的发射线圈与电动汽车无线充电接收端的接收线圈匹配充电时,获得发射线圈的阻抗ZGA;步骤二、将ZGA的值导入预设的阻抗图中;步骤三、检测阻抗ZGA的值是否位于阻抗图的可完全互操作区域或可容忍互操作区域;若是,则判定电动汽车无线充电发射端与电动汽车无线充电接收端可互操作;否则,判定电动汽车无线充电发射端与电动汽车无线充电接收端不可互操作。
