Abstract:

This paper uses the UML unified modeling language to perform electric vehicle charging station energy management system modeling for charging,power grid load adjustment and the maximum profit of charging station.The overall functions of the electric vehicle charging are analyzed and integrated from the angle of energy scheduling with energy management system based on multi agent system (MAS).All parties in the charging are considered as adaptive agents,whose decision-making is optimized through interactive communication,thus simplifying the control problem of complex system.A comprehensive development model framework is established by the UML object oriented development,laying the foundation for the subsequent system software engineering and hardware configuration.

Key words: electric car;energy management system for electric vehicle charging station;multi-agent system;unified modeling language
