Employing an extensive system dynamics market agent model of the EU light-duty vehicle sector, this paper investigates the interaction between the provision of charging infrastructure and the uptake of electric vehicles. Focusing on subsidies for both infrastructure deployment and vehicle purchase, and set within the context of the EU fleet CO2 emission regulation for new cars and light commercial vehicles, our findings suggest that infrastructure provision does improve the utility of a plug-in electric vehicle, but may have a weaker correlation with uptake than other policy options.
