In order to improve the efficiency of reliability verification of the e-Axle under mechanical load and thermal load environment, this paper, taking the three-in-one e-Axle as the research object, analyzed the failure mechanism and influencing factors of each subsystem by comprehensively considering the actual operating environment and working conditions of the e-Axle, and studied the acceleration process and calculated equivalent test time according to the accelerated failure logic under different test conditions. The results show that the accelerated life endurance test method can support the reliability verification of the e-Axle.
