At the heart of automotive revolution: Battery 101A battery pack that powers electrified vehicles consists of individual battery cells and modules organized in series and parallel. A cell is the smallest unit of a battery, comprised of 4 key components including cathode, anode, electrolyte and separator. The characteristics of a battery cell play a pivotal role in the overall performance of electrified vehicles. There are various forms of a cell such as prismatic, cylindrical and polymer, and Samsung SDI offers prismatic battery cells for automotive applications. A module consists of multiple cells connected in series and/or parallel, encased in a mechanical structure. The compact and stackable design of Samsung SDI prismatic battery cells facilitates easy cell modularity and is ideal for various configurations. A battery pack is assembled by connecting multiple modules together in series or parallel with sensors and controllers including battery management systems and thermal management systems, and then encased in a housing structure as a final battery product designed specifically for each vehicle model.
