Electric vehicles (EVs) even though viewed as emission free and environmental friendly can still contribute towards indirect emissions if charged by using traditional fossil fuels. The integration of renewable energy sources is hence paramount to approach a completely carbon free future of E-mobility integration in the transportation sector. This thesis project aims at designing and implementing a photovoltaic (PV) based charging station for a fleet of ten EVs in the TU Delft campus. The complete solar powered charging station for EVs is hence called as E-Hub, which aims to facilitate the development of e-mobility in the TU Delft campus by providing charging facilities that can be scaled up along with a competitive business model. At first, the driving pattern of EV owners in the Netherlands is analysed to categorize employees and visitors. The driving pattern is used to estimate the load profile and the yearly charging demand for the EV fleet in the TU Delft campus. Calendar effects such as holidays and vacations are taken into account to accurately predict the charging demand. A thorough PV system design is carried out to meet the estimated charging demand, followed by a practical and economic feasibility study. The components required for the E-hub are listed along with an estimation of the initial investment. Later an optimisation model is used to develop power management algorithms for optimum economical performance based on the designed technical framework. Nine charging strategies are considered for both summer and winter conditions. The performance of each strategy is analysed under the estimated load profile and designed PV system. The model is also extended to explore the integration of battery systems and its effect on the technical and economical performance of the E-Hub. This battery system can hence function as a virtual power plant to supply power back to the grid in times of peak load and facilitate in stabilization of the grid. A proof of concept is then built to test the developed power management algorithms in the Electrical Sustainable Power Lab (EWI, TU Delft). The Eneco SolarEdge and Tesla Powerwall (ESTP) set-up is used to study the power flow and a system is designed to dynamically control and monitor the ESTP set-up. It was concluded that such a system is technically and economically feasible and can be implemented in the university to provide an environmentally friendly charging infrastructure to electrical vehicles.
