Effect of Battery Pack Stiffness Depending on Battery Cell Types in Cell-to-Pack Technology
High-voltage batteries used in electric vehicles use hundreds or thousands of battery cells. Because a large number of battery cells are used, installing each one into a battery pack causes many difficulties in production. Therefore, traditionally, multiple battery cells are composed of several battery modules and then assembled into a battery pack. However, recently, Cell-to-Pack (CTP) technology that configures battery cells directly into a battery pack is being developed to increase energy density of a battery pack. This is because parts needed for battery modules can be removed, which can have various advantages. Because modules are eliminated in CTP technology, the method of installing battery cells in a battery pack will also be modified and the effect battery cells have on the stiffness of a battery pack will also change. In this study, the differences in stiffness of battery packs based on CTP technology developed for various battery cell types are analyzed. In particular, battery packs with CTP technology are generated based on pouch-type battery cells and prismatic battery cells and how each type of battery cell changes the stiffness of a battery pack is analyzed.
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.
