Abstract: The features of charging facilities for electric vehicles are described.The functional requirements of each part of the supervisory and control system are determined by a system demands analysis and system design thoughts are then proposed.According to the classification and Abstract of the function service,a design scheme with layered architecture is provided.The supervisory and control system is divided into four layers,namely,the system platform layer,the support service layer,the service layer and the application layer.Three communication network configuration modes for the supervisory and control of charging facilities in the major application environments are proposed.Realization of each layer of the cross-platform supervisory and control system software is given.Field monitoring results show that the system is satisfactory.
