Description

Battery Pack The present invention relates to a battery pack. Recently, as awareness of the crisis regarding the environment and the depletion of petroleum resources has increased, research and development of eco-friendly electric vehicles (EVs) has been gaining prominence. Electric vehicles include PHEVs (Plug-in Hybrid Electric Vehicles), BEVs (Battery Electric Vehicles), and FCEVs (Fuel Cell Electric Vehicles). Electric vehicles use battery cells as a power source, which is why they require charging. Efforts to increase the charging speed of electric vehicles are ongoing to improve user convenience. Meanwhile, development of replaceable battery systems that allow for the replacement of battery packs is continuing recently to improve user convenience for electric vehicles.
