This paper summarizes the existing work on implementation models of charging stations. It aims to draw up a comparative overview of the approaches that have been used until 2020 to simulate and assess the impacts of location strategies of charging infrastructure. In particular, three categories of approaches are identified. Then, we analysed, for each approach, both technical and economic factors , in order to provide a complete analysis to stakeholders involved in EV charging infrastructure design and planning. Finally, a list of recommendation for future research works are provided in order to develop models that are closer to reality.
