The invention relates to a speed measurement method, device and equipment for a wireless charging electric vehicle and a storage medium. A stress detection device and a magnetic induction device are arranged on a coil of a wireless charging receiving end of the electric vehicle. The method comprises: using the stress detection device for obtaining the stress borne by the electric vehicle when the wireless charging receiving end is connected with a wireless charging sending end, and the wireless charging sending end being arranged on the road surface; acquiring the field intensity of a magnetic field where the electric vehicle is located by using the magnetic induction device when the wireless charging receiving end is connected with the wireless charging transmitting end; and determining the speed of the electric vehicle based on the effective cutting length of the wireless charging receiving end for cutting the magnetic induction lines in the magnetic field, the stress and the field intensity. According to the invention, the cost of the system can be reduced on the basis of realizing accurate speed measurement of the electric vehicle.
