Abstract

Utilisation of pure electric vehicles (EV) enables a step change in vehicle efficiencywhen compared to those powered by an internal combustion engine. Cenex, theUK's Centre of Excellence for Low Carbon and Fuel Cell technologies specialises inunderstanding the real-world and whole-vehicle performance of low carbon vehiclesand in collaboration with the University of Lincoln and Loughborough University hasundertaken chassis dynamometer testing of an OEM electric passenger car. Thispaper presents the methodology and results of laboratory testing that studied thewhole vehicle efficiency and energy consumption over a range of vehicle speed andbattery load points and reports on the charging and battery efficiency of the EVduring the test period to present a total plug-to-wheel EV efficiency when operatedover both regulated and real-world drive cycles. © 2012 Woodhead Publishing Limited.
