The overall project objective is to optimize the entire charging chain - from energy provision to the end user - to create a clear benefit for all stakeholders. Therefore, a ubiquitous on-demand charging solution based on an optimised charging network considering human, technical and economic factors along the entire charging chain shall be developed. The project will study how people use electric vehicles and analyse the energy system and power grid to understand how they will behave in the future. This research will help predict the actions of electric vehicle owners and companies that use electric vehicle fleets, and will identify any problems in the electric grid and energy system.
