As the “heart” of new energy vehicles, the power package is the primary power source of the car and one of the key assemblies of electric vehicles; it plays a decisive role in the vehicle's performance, and the battery pack's performance is affected by parameters like the number of cells, energy. . Unlike regular car batteries, EV batteries are designed with multiple layers— cells, modules, and packs —each playing a crucial role in storing and delivering energy. But what exactly goes into these powerhouses, and how do they function seamlessly to keep your car moving? From lithium-ion cells. . In this paper, our attention is focused on the architectural modifications that should be introduced into the car body to give a proper location to the battery pack. The required battery pack is a big, heavy, and expensive component to be located, managed, climatized, maintained, and protected. Different models of EV battery packs have been analyzed to. . The journey of a power battery is one of careful aggregation, progressing from the smallest individual units to a comprehensive, intelligent system ready to power an electric vehicle. This process can be visualized as a clear progression: Battery Cell → Module → Battery Pack. Driving a vehicle. . ack box bodies with high stability requirements. The structural role is more obvious, which has led more experts and scholars to st uctures had large volume and complex structures. By establishing models in virtual prototypes and simulating and analyzing the performance parameters of the battery. .
