Abstract
One of the barriers for the 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 paper, 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 operate 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 optimization using a graph-based shortest path algorithm. The proposed method exploits inter-vehicle 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.
Highlights
There is an increasing interest among government agencies, research institutions and industry around the globe in improving urban living while reducing the environmental impact
The solution we propose in this paper builds on the use of inner city buses as mobile energy disseminators (MEDs), it does not suffer from the pitfalls associated with static charging stations
All the parametric side roads of the area in which the static charging station (SCS) and MED charging models are located are used as starting points for the dynamic wireless charging system with the Algorithm 2 FindBestEnergyPoint(sk )
Summary
There is an increasing interest among government agencies, research institutions and industry around the globe in improving urban living while reducing the environmental impact. The experiments show that the driving range and the overall travel time is improved by about four times in the dynamic charging system involving MEDs. This paper proposes a dynamic wireless charging method for EVs using the city buses as MEDs. Our proposed technique is the first in literature according to our knowledge that uses the ordinary city buses and trucks for recharging needs of EVs without any extra infrastructure. A dynamic wireless method is proposed for the charging of the EVs on the move This method uses existing city buses as MEDs, without the need for underground or other infrastructure; VOLUME 6, 2018.
