Battery Pack

A battery pack is made of multiple identical battery cells or modules, connected in series, parallel, or a mixed configuration to achieve a specific voltage and capacity. It functions as asingle, integrated unit within a casing. Additionally, battery packs require a battery management system (BMS) to monitor cell voltage and temperature, and tobalance cells to maximize safety and lifespan. They are typically used inelectric vehicles (EVs), laptops, and cordless tools.
