Research on Electric-Vehicle Charging Station Technologies Based on Smart Grid

The smart grid´s cell unit -smart microgrid combins with the advantages of distributed generation systems (DGS) and big power grid supply systems, The proposed of smart grid has brought new opportunities and challenges for the development of electric vehicle charging station systems. This paper introduces the domestic and foreign research status about electric vehicle charging station, puts forward three-level network structure about electric vehicle charging station system based on smart grid, discusses the key technologies about electric vehicle charging station. The developing prospect and research direction of electric vehicle charging station are analyzed in depth.
