As a huge network involving deep cyber-physical integration of energy systems and information systems, energy internet possesses features of open and sharing, which brings challenge to the access, control and transmission of energy on user side. Aiming at the issues of integrated energy management on user side in the context of energy internet, the concept of energy internet access equipment is proposed as well as its features that obviously differ from energy router. Then, from the perspectives of planning and dispatching, operation management, and energy service, the application fields of energy internet access equipment are thoroughly introduced. Next, six key technologies included in energy internet access equipment are described, including equipment feature recognition, demand response, blockchain, big data, integrated energy management and electricity market, from which the relationship between energy internet access equipment and these key technologies is elaborated. Lastly, the engineering implementation and future challenge of energy internet access equipment are briefly introduced, hoping to provide some reference and guidance for effective and convenient access of user-side equipment to energy internet in the future.
