In the process of replacing carbon based fuel with renewable energy, into the energy generation cycle of the world, mobility is considered to be one of the important sectors in which enormous progress can be implemented. Business tycoons are introducing electric vehicles which fascinates people. However, there is yet a stabilized solution to be found for charging electric vehicles with green energy on the basis of large scale implementations. In the Netherlands, there are more bikes than the total population and with the number of e-bikes increasing every year it would be brilliant to charge the e-bikes with decentralized renewable energy than with the conventional way of purchasing energy from the grid. In this thesis such a charging facility called the Solar Mobility Hub is studied thoroughly and validated for performance.

By validation, it means the system was tested for the number of e-bikes it can charge throughout the year as an autonomous system without loss of load. Instead of going into complete modelling a different approach was pursued. E-bike ride programs were conducted for a few months with the help of volunteers from which technical data necessary to develop exclusive full year load profiles were obtained. Thereby, generating two kind of load profiles - work to home (commute mode) and bike sharing (sharing mode). It was found that the solar mobility hub was capable of charging 19 e-bikes as a 100 % reliable autonomous charging infrastructure for commute mode and 15 e-bikes for sharing mode. Furthermore, advanced simulations were performed with system modifications like change of PV array tilt and increased battery bank. Finally, a performance analysis on the system was conducted and the reasons for the variation in performance were analysed. Furthermore, improvements and suggestions necessary for making such a BIPV commercially successful are provided.
