Electric Vehicle (EV) Batteries

Electric vehicle (EV) batteries are composed of cells, modules, and a pack. These components build in sequential order within the battery, meaning a group of cells forms a module and a group of modules forms a pack. Though cells are the smallest component, they are the basis of EV batteries and play a major role in vehicle integrity and performance. A cell must include high capacity per unit volume to achieve maximum performance within the confines of the vehicle. The cell must also be capable of enduring shocks transmitted while driving and possess high reliability and stability to withstand a range of temperatures. 

Even with three basic components, the exact battery design depends on the type of electric vehicle. Regardless of what design they use, EV battery manufacturers are uniformly focused on achieving greater energy density, cycle life, and safety. During production, reliable and stable manufacturing processes are essential to prevent degradation and minimize waste.
