As we all know demand of electric vehicles is much more but still electric vehicles are evolving and limited. This review paper first deals with the concept of electric vehicles, market share their characteristics and charging facilities. Then after study about traffic assignment problems and problems related to charging of electric vehicles. Moreover these vehicles are noiseless, pollution free and less maintenance.[1] Index terms- Electric vehicles, Network modelling, Traffic assignment problem, Vehicle routing problem, charging facility location problem. INTRODUCTION Carbon emissions and greenhouse gases are one of the most critical issue according to the policy makers since 1998. At present transportation is 98% dependent on fossil fuel which is affected by changes in energy resources. Government and automobile companies have recognized the value of alternative fuel vehicles for green transportation and implement economic policies for support of electric vehicles market and overcome from issues related to electric vehicles. Plug –in hybrid vehicle (PHEV) is one of the type of AFVs which reduces the emission of greenhouse effect. The hybrid gasoline –EVs is beneficial in future because it reduces the gasoline emission and green house emission from 30% to 50% without changing of vehicle class. Limited battery capacity is one of the major issue due to which it allows ranges between 150 and 200km. The widespread use of plug – in electric vehicles (PEVs) calls for fundamental changes of the existing network flow modelling tools as well as for evaluation of transportation development plans. In this paper we explore different topics with respect to network modelling of EVs. The respective topics are described as follows:  In this section we discuss about the topic‘ Charging station design and location studies’ in which we studies about battery charging station and battery swapping station (BSS) location as well as their design.  In section ‘PEV market potential, demand and behavior study’, the PEV market potential and it’s demand are reviewed from aspects of EVs, challenges and opportunities.  In section ‘TAP of a vehicles with range limit’, studies about traffic assignment problems for electric vehicles network  In section ‘Network design and bi-level model’, in this section we study about problems related to network designing of EVs.[2] CHARGING STATION DESIGN AND LOCATION STUDIES Charging is one of the major issue in case of electric vehicles so, charging facilities must be available for electric vehicle drivers. Government and EVs companies must have to seriously concerned about where to locate charging station and which type of charging station to locate because of the high cost.[9]the main power conversion system comprises of an AC to DC converter. The converter must have certain properties in order to safe, secure as well as
