Technical Field

[0001] This application relates to the field of electrical automation technology, and in particular to a portable power management terminal with fast multi-source access and plug-and-play functionality. Background Technology

[0002] Currently, known power management terminals mainly adopt IP54 protection level enclosures, integrating intelligent instruments or controllers such as PLC modules and measurement and control devices to monitor the operation of power distribution switches and meet the needs of intelligent power distribution and consumption. However, current power management only considers application scenarios of single or dual power supply switching input and multi-power supply output. Multiple power supplies cannot be directly connected in parallel at the same time to expand the power supply, thus failing to meet the needs of combining current to jointly supply power to the load and improve load capacity and power supply reliability. Moreover, it does not yet consider power supply with quick access and plug-and-play output. In addition, microgrid power systems need to consider the application scenarios of mobility and modular design. A single power supply system can provide power independently or multi-source AC connection to expand power supply to the outside. Often, a power management terminal is needed as a carrier to realize system connection. In order to overcome the needs of existing power management terminals, such as the inability to connect multiple AC sources in parallel on a common bus and communication access, and the inability to achieve priority power supply for output, this application provides a portable multi-source quick access and plug-and-play power management terminal.
