Performance Evaluation of Battery Electric Vehicles – A Computational Study

Technological innovations have brought significant developments in internal combustion engine-powered automotive vehicles. With the automotive population explosion, issues of fossil fuel crisis and environmental degradation are enticing the researchers to divert focus on alternate fuels and alternate power sources to keep the automotive industry alive. Owing to global warming and associated pollution hazards, many nations are imposing stringent emission norms. To meet the target zero emission levels, researchers are seriously working to develop viable electric vehicles. In this regard, developed nations have done their might to commercialize different variants of electric vehicles. Computer simulations are being tried out to arrive at optimal designs. Electric vehicles are powered by various power packs available commercially, viz,. Pb-acid, Ni-MH, Ni-Cad, etc., with the choice lying in the application. The present work deals with the comprehensive modeling of battery performance parameters using the software MATLAB. It deals with the evaluation of performance parameters such as acceleration performance and range considering simplified Federal urban driving schedule, European driving cycle and Indian driving cycle. Commercially available electric car JOLT EVION is chosen for validating the modeling results. Modeling studies revealed that there is still larger scope for Pb-acid power packs as others pose either environmental hazards or cost constraints. Few of the myths in the usage of electricity are found to be highly deceptive. It is felt that government incentives for automotive industry may promote commercial use of electric vehicles.
