Battery Pack

A battery pack is made of multiple identicalbattery cells or modules, connected in series, parallel, or a mixedconfiguration to achieve a specific voltage and capacity. It functions as asingle, integrated unit within a casing. Additionally, battery packs require abattery 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.
