This invention relates to the field of power management technology, and particularly to an intelligent integrated power system and control method based on multi-source collaboration, including a main power module, a backup power cluster, an energy management unit, a voltage adaptation module, a status monitoring unit, a communication module, and a load interface. Compared to existing technologies that typically use a single type of battery pack as a backup power source, which suffers from slow response speed and difficulty in withstanding instantaneous high-power surges, this invention employs a heterogeneous energy storage system composed of parallel lithium battery packs and supercapacitor modules as the backup power cluster, and uses a bidirectional DC / DC converter for intelligent control. This solution fully leverages the different advantages of lithium batteries (high energy density) and supercapacitors (high power density and rapid response), enabling the system to provide both long-term backup power support and instantaneous high-power discharge, thereby significantly improving the dynamic response capability, power support reliability, and overall service life of the backup power source.
