Design of interactive terminal for interaction between electric vehicles and grid

Electric vehicle (EV) has become one of the important development direction of the automobile industry generally recognized by the international community, as it has a good environmental effect and the flexible use form of energy. For the realization of the interaction between EV and grid, this paper studies and designs the interactive terminal to balance load and improve utilization of the grid. The terminal adopts high-end ARM platform and embedded Android operating system to realize both-way interaction of information and energy between EV and grid with means of communication such as CAN, 3G and Internet. Based on giving the design ideas of the intelligent terminal overall structure, this paper describes the hardware/software architecture technology, design methods and functions. The interactive terminal can deploy unified charging and discharging of EV according to the control mode of interaction, and give full play to the economic and social benefits of large-scale EV.
