Energy Internet access equipment is a medium for energy use facilities accessing to the Energy Internet. This paper elaborates the basic concepts and features of Energy Internet access equipment. According to the universal serial bus(USB)concept used in computer field

this paper develops an Energy Internet access equipment for multi-user interaction based on cyber-physical system(CPS)

i. e.

energy USB system(EUSBS). Firstly

the CPS ideology and functions of EUSBS are introduced

and its overall framework and application topology are designed. Based on these

the software and hardware of EUSBS are developed separately

which focus on hardware system framework design

development of five major EUSBS equipment and experimental tests. In addition

the overall architecture design and main functional modules of the software system are briefly introduced. Moreover

the energy management of a commercial building is analyzed by installing EUSBS and configuring distributed equipment. The results preliminarily verify that EUSBS can monitor and coordinate access equipment in real time

thus realizing dual circulation of energy flow and information flow. Finally

the future applications of EUSBS are prospected.
