Charging station, as one of the most important aspects of electric vehicle industry, must be able to adapt the fast development of electric vehicles. In this work, a hybrid solar-wind powered charging station was designed to provide electricity for the electric vehicles according to the wind and solar condition of the coastal areas in Tangshan. The key components including wind turbines, PV modules, batteries, an inverter and other controllers were considered. In order to determine the capacities of the components, LPSP was used as a control condition to obtain the configurations achieving the demand energy and the costs of every configuration as the other control condition were calculated to optimize the system. At last, the minimum-cost configuration achieving the demand energy was found as the result of the designation.
