Investigation on performance evaluation of electric vehicle batteries under different drive cycles

Abstract

The drive cycles influence the design, sizing, rating, and selection of electric vehicle components. So, it is required to test the Electric Vehicle (EV) on different standard drive cycles in the simulation environment before testing in real-time to evaluate the life cycle and determine the efficient and economical design of the EV. Different standard driving cycles are available to evaluate the performance of the EVs, but these drive cycle patterns vary from country to country due to differences in road conditions, traffic density, and driver disciplines. The range and performance of the EV battery mainly depend on its cell chemistry. In this research paper, the performance of different EV batteries on various standard international and Indian drive cycles has been evaluated. To determine the performance of the EV battery, an EV drive train test system has been developed, Nissan leaf 2018 EV model data has been taken in this paper. FOC control strategy for PMSM traction motor has been developed. To reduce the harmonics and improve quality of the switching losses, Space Vector Pulse Width Modulation (SVPWM) algorithm has been adopted for PWM Inverter. Battery energy consumption, and cost per charge based on the distance travelled by the vehicle are calculated for comparing different EV batteries to evaluate their performance.
