A battery pack is defined as what?

A battery pack is best defined as a mechanical assembly of battery cells. This definition highlights that a battery pack is more than just a single battery or a charging device; it is an integrated system that combines multiple individual battery cells. By connecting these cells together in a specific configuration, a battery pack can achieve a desired voltage and capacity, which is essential for powering various applications, particularly in electric and hybrid vehicles.

The term "battery pack" typically encompasses not just the cells but also the necessary components for ensuring the cells operate safely and effectively. This can include modules, interconnects, and any protective circuitry needed to monitor and manage the performance of the cells within the pack.

Understanding this definition is crucial because it emphasizes that the functionality and design of a battery pack are dependent on the arrangement and integration of its cells, rather than being limited to a single unit or a separate charging system.
