Abstract
In response to the climate crisis, nations are working to reduce emissions and improve energy efficiency, particularly in the transportation sector through the adoption of electric vehicles. However, the current official test methods for evaluating battery electric vehicle (BEV) energy economy and single-charge driving range are time-consuming, creating challenges for testing institutions and delaying the release of new models. The objective of this study is to compare the energy economy and single-charge driving range of BEVs using the different test methods, the full depleting test (e.g., multi cycle test (MCT), short multi cycle test, short multi cycle test plus) and partial depleting test (e.g., short process test (SPT)), with the aim of reducing the testing time on the chassis dynamometer. As a result of testing with three BEVs with different battery capacities, the test duration on the chassis dynamometer could be reduced by up to 85% compared to the MCT that is authorized test method by government. Each test has different repeatability, and SPT has a higher deviation from the MCT test results than other test methods. Overall, the study can provide reliable research outcomes conducive to the future improvement of official energy economy and single-charge driving range test standards for BEVs in each country.
期刊介绍：
The International Journal of Automotive Technology has as its objective the publication and dissemination of original research in all fields of AUTOMOTIVE TECHNOLOGY, SCIENCE and ENGINEERING. It fosters thus the exchange of ideas among researchers in different parts of the world and also among researchers who emphasize different aspects of the foundations and applications of the field.
Standing as it does at the cross-roads of Physics, Chemistry, Mechanics, Engineering Design and Materials Sciences, AUTOMOTIVE TECHNOLOGY is experiencing considerable growth as a result of recent technological advances. The Journal, by providing an international medium of communication, is encouraging this growth and is encompassing all aspects of the field from thermal engineering, flow analysis, structural analysis, modal analysis, control, vehicular electronics, mechatronis, electro-mechanical engineering, optimum design methods, ITS, and recycling. Interest extends from the basic science to technology applications with analytical, experimental and numerical studies.
The emphasis is placed on contributions that appear to be of permanent interest to research workers and engineers in the field. If furthering knowledge in the area of principal concern of the Journal, papers of primary interest to the innovative disciplines of AUTOMOTIVE TECHNOLOGY, SCIENCE and ENGINEERING may be published. Papers that are merely illustrations of established principles and procedures, even though possibly containing new numerical or experimental data, will generally not be published.
When outstanding advances are made in existing areas or when new areas have been developed to a definitive stage, special review articles will be considered by the editors.
No length limitations for contributions are set, but only concisely written papers are published. Brief articles are considered on the basis of technical merit.
