Abstract

An automated system to provide gas leak detection during battery manufacturing includes a battery system. A video of a gas leak occurring during a manufacturing stage of the battery system includes the gas leak as a gas vapor. A location of the gas leak is determined. A leak intensity value of the gas leak is identified to determine if the gas leak is minor and is less than or within a predetermined window or threshold permitting acceptance of the gas leak without repair, or if the gas leak requires further action including repair of the battery system.
