This paper presents a model of market development for an industry sector of plug-in electric vehicle (PEV) producers, and charging infrastructure availability for PEV users. The authors demonstrate that, if the behaviors of the economic players were left to the workings of the market mechanism alone, the sector may see no phenomenal growth, however, various policy initiatives can promote the development of the PEV markets to take-off for continuous growth. Our model intends to facilitate the assessment of various policy initiatives to support boosting the proliferation of PEV into the community. The model is also of use to evaluate quantitatively the effects of the PEV proliferation for lowering carbon emissions.
