step S10, after the power supply system starts to supply power, detecting the voltage value and the power supply time of each switching power supply in real time, and acquiring the initial total capacity of the power supply system;
Step S20, calculating the power capacity of each switching power supply according to each voltage value and each power supply time, and the real-time total capacity of the power supply system;
it should be noted that, in the present embodiment, the power management method is applied to a power system, and the power system includes: the switching power supplies can be connected in parallel or in series, one or more loads can be respectively connected with the switching power supplies, and the power supply system is integrally connected with the loads.
In this embodiment, after the power supply system starts to supply power, the voltage value and the power supply time of each switching power supply are detected in real time, and the initial total capacity of the power supply system is obtained, then the current remaining power supply capacity of each switching power supply is calculated in real time according to the respective voltage value and the power supply time of each switching power supply and the initial capacity of each switching power supply, and the real-time total capacity of the power supply system is obtained according to the power supply capacities of all switching power supplies.
Step S30, if a target switching power supply exists in the power supply system, adjusting the feedback voltage of the target switching power supply based on the power supply capacity of each switching power supply so as to adjust the output voltage of the target switching power supply to enable each switching power supply in the power supply system to be in an equilibrium state, wherein the target power supply capacity of the target switching power supply is different from the power supply capacities of other switching power supplies in the power supply system;
In this embodiment, if one or more target switching power supplies are provided in the power supply system, the target power supply capacity of the target switching power supplies is different from the power supply capacities of other switching power supplies in the power supply system, and the number of the target switching power supplies is smaller than that of the other switching power supplies, the feedback voltage of the target switching power supplies is adjusted based on the power supply capacities, so as to adjust the output voltage of the target switching power supplies, thereby adjusting the output power of the target switching power supplies, so that each switching power supply in the power supply system is in an equilibrium state, and the influence on the service life of the switching power supplies due to the fact that some or some switching power supplies are powered up faster or slower than the other switching power supplies is avoided.

Therefore, the capacity of the switching power supply is detected by integrating the real-time voltage and the power supply time, the switching power supply in the power supply system is balanced to supply power, and then the load is closed in a grading manner according to the priority of the load.
