[0002] The main components of the power management system are as follows, generally including the main control circuit, battery packs that can be charged and discharged multiple times, DC transformers, DC distributors, AC rectifiers, inverters, external racks and internal power distribution buses, power management systems According to the needs, it can provide DC and AC power supply of different frequencies for different loads, and at the same time control the charging and discharging behavior of the battery to ensure the stable operation of the power supply system and the load system; in the existing power management system related technologies, multiple With the support of single or multiple power supply terminals, the power manager monitors the power input process of multiple corresponding loads, but it cannot accurately evaluate the battery SOC and SOH, and the existing distributed power management system usually uses power input The terminal bus connects multiple power input management units, which limits the flexibility of its architecture. The power output terminal does not adopt a distributed layout in general applications, which limits the versatility of its architecture. At the same time, the mismatch between input and output terminals is also serious. Limits the transmission and utilization of electric energy

It is impossible to optimize the charging and discharging process for the battery pack with degraded performance, and it is also impossible to record and analyze the user's electricity consumption habits, which further reduces the utilization rate of electric energy; at the same time, the transmission of electric energy on the input bus reduces the utilization rate of electric energy, and when the output When the actual output power of the terminal is low, there are serious safety hazards

Decentralized power management increases the cost and operating power consumption of the power management system, reduces system compatibility and stability, cannot perform encrypted remote communication and monitoring, and increases the cost of manpower for power management system maintenance

[0003] All in all, with the blessing of 5G technology in the future, in the practical application of the Internet of Things, all kinds of electrical equipment have put forward more requirements for power supply and supporting power management system: the safety and stability brought by a single power supply source Uncontrollable; repeated investment in power management IC and supporting circuits; traditional power management requires labor costs for on-site monitoring; energy utilization cannot be further improved, and the battery status cannot be monitored and controlled in real time and efficiently; the risk of remote unauthorized personnel intrusion
