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：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
