The invention relates to a wireless charging electromagnetic field measurement system and method for an electric vehicle. The electric vehicle is provided with a secondary coil thereon. A primary coilis arranged on the ground. The primary coil is connected with a power supply. Included are a vehicle parking platform, an automatic measurement device and a control analysis background. The control analysis background is connected with the vehicle parking platform and the automatic measurement device, separately. The electric vehicle is parked on the vehicle parking platform, so that the primarycoil and the secondary coil are opposite to each other. The automatic measurement device performs electromagnetic field measurement one by one for measurement points set on an external virtual surfaceof the electric vehicle, and the measured data are analyzed and processed through the control analysis background. The system and method of the invention can provide a convenient, efficient, and reliable solution for the electromagnetic field measurement of the wireless charging system of the electric vehicle, realize automatic measurement, and save manpower and time.
