This paper develops a more accurate range prediction for electric vehicles (EVs) resulting in a routing system that could extend the driving range of EVs through calculating the minimum energy route to a destination, based on topography and traffic conditions of the road network. Energy expenditure of EVs under different conditions is derived using high resolution real-world data from the SwitchEV trial. The SwitchEV trial has recorded the driving events of 44 all-electric vehicles covering a distance of over 400,000 miles across the North East of England, between March 2010 and May 2013. For each of the vehicles, the global positioning system (GPS) and time-stamp as well as the battery drain and energy regeneration (due to breaking and deceleration) were recorded on a second by second basis. Linear models are used to determine the energy expenditure equations and Dijkstra's graph search algorithm is used to find the route minimising energy consumption. The results from this paper are being used to better inform the decisions of the smart navigation and eco-driving assist systems in electric vehicles thus improving the intelligent transport systems (ITS) provisions for EV drivers. The outputs of the research are twofold: providing more accurate estimations of available range and supporting drivers’ optimisation of energy consumption and as a result extending their driving range. Both outputs could help mitigate range anxiety and make EV’s more attractive to potential customers.

Notes: Researched new algorithms that utilised data from Europe’s largest electric vehicle trial (SwitchEV TSB £10.5m) for a more accurate estimation of the available range of an electric vehicle. Now being used by industry to develop a Smart Range Estimator and EV Navigation systems for future vehicles (Dr Colin Herron, Zero Carbon Futures, Tel. 07872417046). Recently awarded by EU the SmartCEM project with demonstrations of the smart range extender will commence in 2014 in six European regions including North East England integrated with the regional EV charging infrastructure Charge Your Car (Contact Josey Wardle, Charge Your Car, tel. 07710013793)
