The invention discloses an electric vehicle motor matching method, device and equipment and a storage medium, and belongs to the technical field of electric vehicles. The method comprises the following steps: determining target peak power of a required motor according to a dynamic property index of the electric vehicle; according to the energy consumption condition of the electric vehicle under the common working condition, the corresponding target vehicle speed and target driving force of the electric vehicle under the working condition interval with the highest energy consumption proportion are determined; based on the target vehicle speed and the target driving force, the target rotating speed and the target torque of the needed motor are determined; the motors with the matching parameters meeting the set requirements in the alternative motors are the needed motors, and the set requirements include that the peak power is larger than or equal to the target peak power, and when the motors work at the target rotating speed and the target torque, the working efficiency of the motors is larger than a set high-efficiency threshold value. According to the method, the motor can be matched from the two aspects of dynamic property and economical efficiency, and comprehensive optimization of the dynamic property and the economical efficiency of the whole vehicle is achieved.
