Objectives

1. To evaluate real driving energy consumption of an electric vehicle in case of Kathmandu

2. To build an energy consumption model for real driving cycle

Summary

Introduction of large number of electric vehicles (EVs) on the roads of Nepal calls for an extensive study to assess real performance of EVs for the specific road condition. Roads of Nepal are characterized by poor quality, lack of management during wet seasons and traffic congestions which is in no way comparable to the road condition assumed for standard driving cycles. Due to this reason, the performance indicated by manufacturer for any EV is certain to be different than that would be for the real case. This project aims to formulate a real driving cycle representing the road status of Nepal based on the effect on aerodynamic drag, rolling resistance, mechanical power and battery power. The data will be used to obtain battery to wheel efficiency considering the predominant influencing parameters. The data obtained from simulation will be validated by comparing it with real driving case. The difference in performance and energy consumption recorded by standardized testing and real testing will help conclude the actual benefit of EV adoption.
