Abstract

Supply systems to the electrical vehicles are becoming extremely important in the actual context. Thus, this paper presents a DC supply system for electrical vehicles. It can be used for fast or slow charge. This system was developed taking into consideration the use of Renewable Energy Sources (RES). Thus, a wind generator and a Photovoltaic (PV) system connected to the DC bus were also considered. Due to the intermittent nature of the energy generated by the RES storage systems were also considered. In this case were considered batteries and supercapacitors to support the system during the fast transients. A connection of the DC supply system with the grid was also considered in order to support the charging system, when the energy generated by the generators and storage systems are not enough. Besides that, this connection is also made in order to support the grid, when necessary. So, in situations in which is required the support of the grid, the system can provide active and reactive power. The active power can be supplied by the RES and storage systems, but also by the electric vehicle when available. The models of the several systems are presented. The control of the all components of the system is also provided. Several results are presented in order to verify the effectiveness of the global system.
