아이오닉 EV의 전기 구동 시스템 성능 분석

Abstract

Battery Electric Vehicles(BEVs) are successfully penetrating the vehicle market with powerful motors and efficient battery systems, features that were unexpected by the consumers. In response to the successful market penetration, global automakers are sharply focusing on manufacturing their own brand names for BEVs. ‘Ioniq’ is the family name of electrified vehicles from Hyundai-Kia Motors. In this study, the Ioniq Electric Vehicle(EV) is tested on a chassis dynamometer, and the test results are analyzed to evaluate vehicle performance. Dedicated tests for a motor or a battery are preferred to examine the performance of the components. It not only requires well-organized testing facilities but also needs considerable time and effort to remove the components from the vehicle. Therefore, we equipped the electric vehicle with measuring devices and analyzed them to investigate vehicle performance and that of its components based on test results obtained from the chassis dynamometer tests. In addition, signals in On-Board Diagnostics(OBD) have been used to improve analysis. Based on the analysis, the accelerating performance and the efficiency of the vehicle were studied, and the characteristics of the motor and the battery were also investigated.
