This paper describes benefits of a hybrid drive-train and presents development work of an experimental prototype of the retrofit hybrid system, implemented on a Proton WAJA. It explains operation of the retrofit vehicle's energy management system and describes a dynamic simulation model for the HEV. Preliminary simulation studies show a fuel reduction of 25 compared to the ICE only-powered vehicle. Economic consideration requires further improvement of the fuel reduction, for the system to be commercially viable. This paper suggests for further research, an improvement to the simple retrofit system and investigation of various energy management strategies, to improve the fuel economy. Finally, this work describes experimental set-up for field testing and hardware-in-the-loop (HIL) simulation of the retrofit HEV. © 2011 IEEE. %Z cited By 9; Conference of 2012 4th International Conference on Intelligent and Advanced Systems, ICIAS 2012 ; Conference Date: 12 June 2012 Through 14 June 2012; Conference Code:93534
