Abstract

The present invention discloses a durability test method, device, equipment and storage medium of an electric vehicle drive motor, wherein the electric vehicle drive motor durability test method includes S10: controlling the drive motor to run according to a first set working condition, and correspondingly obtaining the the first operating parameter of the driving motor; S20: control the driving motor to operate according to the second set working condition, and correspondingly obtain the second operating parameter of the driving motor; and, S30: according to the first operating parameter and the The second operating parameter is to evaluate the drive motor according to the reliability evaluation method set in the set reliability test standard, wherein the first set working condition is set in the set reliability test standard fixed working conditions. In the technical solution provided by the present invention, by setting the first set working condition and the second set working condition, the test time can be extended, the test working condition complexity can be increased, and the qualified drive motor has stronger durability.

Description

technical field [0001] The invention relates to the technical field of performance testing of electric vehicles, in particular to a method, device, storage medium and equipment for durability testing of electric vehicle drive motors. Background technique [0002] Existing electric vehicle drive motors are required to have higher product quality, so strict drive motor durability tests are required before leaving the factory to avoid failures of drive motors and electric vehicles during actual use. Existing durability tests for drive motors of electric vehicles generally operate the drive motors in a test environment with conventional indicators and supernormal indicators, so that the defects of the drive motors can appear in a short period of time, but the test environment Generally, it is set as an ideal working condition. The composition of the ideal working condition is relatively simple. For example, keeping the speed of the driving motor constant does not simulate the ac...
