This article reports an experimental study carried out to investigate the vehicle performance and energy consumption (EC) of an electric vehicle (EV) on three different driving cycles using drive cycle analysis. The driving cycles are the Indian Driving Cycle (IDC), Modified Indian Driving Cycle (MIDC) and Worldwide harmonized Light vehicles Test Cycle (WLTC). A new prototype electric powertrain was developed using an indigenous three-phase induction motor (3PIM), Li-ion battery (LiB) pack, vector motor controller, and newly developed mechanical parts. In this research work, a pollution-causing gasoline car (Maruti Zen) was converted into an EV by using the new powertrain. The EV conversion vehicle was used as the test vehicle. After the removal of the Internal Combustion Engine (ICE) the new powertrain was integrated with the vehicle’s gearbox (GB) system which was configured on a single motor, fixed gear configuration having a gear ratio of 1.28:1. The EV performance tests were carried out on the chassis dynamometer that followed the driving cycles. The maximum speed test showed a top speed of 64 km/h for the EV.…

Published 2018-06-11 by SAE International in United States
To check the regulated emission limits, mass emissions test for a vehicle is conducted on a chassis dynamometer following a driving cycle. However, the driving cycle and laboratory test are different from the real-world driving. This article presents a study conducted on a mid-size gasoline car on chassis dynamometer as well as on-road (real-world). It determines the effect of real-world driving, different drive modes (idle, acceleration, deceleration and cruising) on vehicle emissions and fuel consumption and their comparison with the laboratory data. The emissions tests were conducted on the chassis dynamometer following the Modified Indian Driving Cycle and on the selected traffic routes in Dehradun city using a Portable Emission Measurement System (OBS-2200). It was observed from the study that average on-road emission rates in gram per second were 1.35 to 2.39 times higher for CO, 1.12 to 1.39 times higher for CO2, 2.04 to 2.32 times higher for NOx and 2.17 to 5.0 times higher for THC as compared to the chassis dynamometer test. The test results indicated that the on-road fuel consumption was…
