The present invention relates to the technical field of power electronics detection, in particular to an aging method for an intelligent power supply, comprising the following steps: Step 1, inputting a voltage operation schedule and a load operation schedule in a controller; Step 2, inputting no input voltage to the aging power supply In the case of no-load and no-load, the controller obtains the rated information of the aging power supply; step 3, when the aging power supply has input voltage and no-load, the controller sends a command to the switch unit to connect the corresponding voltage; step 4, When the aged power supply is connected to the load and has input voltage, the aged power supply simulates the user environment and cuts into loads of different natures in stages, and the controller obtains the status information B of the aged power supply under the load state, and judges whether the aged power supply is normal. The invention intelligently detects the ability of the power supply to withstand different loads and adapt to different user environments under high voltage, low voltage and normal voltage.
