One of the barriers to adoption of Electric Vehicles (EVs) is the anxiety around the limited driving range. Recent proposals have explored charging EVs on the move, using dynamic wireless charging which enables power exchange between the vehicle and the grid while the vehicle is moving. In this article, we focus on the intelligent routing of EVs in need of charging so that they can make most efficient use of the so-called Mobile Energy Disseminators (MEDs) which operates as mobile charging stations. We present a method for routing EVs around MEDs on the road network, which is based on constraint logic programming and optimisation using a graph-based shortest path algorithm. The proposed method exploits Inter-Vehicle (IVC) communications in order to eco-route electric vehicles. We argue that combining modern communications between vehicles and state of the art technologies on energy transfer, the driving range of EVs can be extended without the need for larger batteries or overtly costly infrastructure. We present extensive simulations in city conditions that show the driving range and consequently the overall travel time of electric vehicles is improved with intelligent routing in the presence of MEDs.
The EVs attach themselves to one or more MEDs during some part of their journey and until they have enough energy to reach their destination (or get to the closest static charging station). In this way, electric cars are charged “on the fly” and their range is increased while moving along the road. Hence, our proposal does not require significant changes to the existing road network and civil infrastructure @cite_3 @cite_8 @cite_14 and, unlike other proposals @cite_21 , does not pose any health hazards.

The growth of the Electric Vehicle (EV)'s market is strongly conditioned by the availability of cost-effective and reliable charging infrastructures. In the current state of the technology, the limited capacity of the batteries limits EV's market to urban moves. The rapid deployment of charging stations in urban areas is a real challenge. In this paper, we introduce an original approach consisting in reusing existing public lighting infrastructures for that purpose. Two main advantages characterize our solution. First, charging stations can be deployed rapidly without costly civil engineering. Second, a fraction of the power non consumed by the lamps at night can be used for the benefit of the charging stations. Meanwhile, such an approach must be achieved while guaranteeing the stability and quality of the lighting system. Wireless charging system for On-Line Electric Bus(OLEB) consists of power inverter, road embedded rail, pickup module and regulator, which have been developed by KAIST several years ago. In this paper, wireless charging system for OLEB with series-connected road embedded segment structure is suggested to implement small-sized power inverter which is easier and cheaper to install near the bus stop. The experimental results are obtained from the experimental setup, from which the applicability of the proposed system is verified through experimental results. The market for battery powered and plug-in hybrid electric vehicles is currently limited, but this is expected to grow rapidly with the increased concern about the environment and advances in technology. Due to their high energy capacity, mass deployment of electrical vehicles will have significant impact on power networks. This impact will dictate the design of the electric vehicle interface devices and the way future power networks will be designed and controlled. This paper presents the results of an analysis of the impact of electric vehicles on existing power distribution networks. Evaluation of supply demand matching and potential violations of statutory voltage limits, power quality and imbalance are presented.
