Abstract: With its rapid development, the electric vehicle charging business faces such problems as single profit mode and slow investment recovery. This paper discusses the feasibility of the power demand of charging facilities to participate in large consumers direct-trading and to accommodate the surplus renewable energies, such as wind power and photovoltaic power. And it also provides the ways and model for the power demand of charging facilities to participate in large consumers direct-trading, and estimates the profit space for the transaction. The provided model in this paper can not only reduce the electricity cost of electric vehicles, but also promote new energy utilization, subsequently realizing the coordinated development of energy industry and electric car industry.

Key words: electric vehicle, charging infrastructure, electric power trade, large consumer
