Teaching aims and requirements

The essence of the energy Internet is that various types of energy work together to improve the user experience and reduce overall operating costs. However, the equations describing other forms of energy such as heat, wind, and chemical batteries are different from the equations describing the circuit model. Therefore, how to analyze the energy Internet in a unified and consistent manner becomes a key academic issue. Based on the pre-requisite courses of university physics, university chemistry and circuit principles, this course is divided into three special topics: (1). “Thermal energy and its conversion”, based on the laws of thermodynamics, introduces the thermodynamic cycle process, thermal power generation technology, Cogeneration technology; (2). "Electrochemistry and its conversion", based on the thermodynamics and kinetics of electrochemistry, introduces electrode reaction and battery technology; (3) "Renewable energy and its conversion", it introduces photovoltaic power generation, wind power generation, pumped storage technology and its integration with power electronics. The course will take several specific energy conversion applications as research examples to deepen students' understandings on energy conversion and practices.
