The invention relates to a wireless charging system performance evaluation method. According to the wireless charging system performance evaluation method, the circuit impedance model of the wirelesscharging system is established so as to acquire the impedance before mutual inductance and the impedance after mutual inductance from the circuit impedance model. And according to the pre-mutual-inductance impedance, the post-mutual-inductance impedance and a third device parameter of the wireless charging system, a first evaluation index and a second evaluation index are respectively obtained. According to the first evaluation index and the second evaluation index, the operation performance of the wireless charging system can be evaluated. According to the invention, the impedance model is utilized to quickly and effectively judge the operation performance of the wireless charging system. 本申请涉及一种无线充电系统性能评价方法。上述无线充电系统性能评价方法，建立所述无线充电系统的电路阻抗模型，以从所述电路阻抗模型中获取互感前阻抗和互感后阻抗。根据所述互感前阻抗和所述互感后阻抗以及所述无线充电系统的第三设备参数。分别获取第一评价指标和第二
