Published purpose
Traditional air pressure based leak test methods are not capable of reliably measuring the leak rates of battery structures to the leak rates required. Using a tracer gas based system instead of air pressure is a method that removes temperature a barometric pressure effects. While Hard Vac Helium Tracer Gas leak testing is a well studied leak test technology, it’s application to battery structures is new, and its application in a high volume automotive production system is new and novel. Development of critical aspects, such as the sealing strategy, motion components, and sensing, while being able to maintain a high vacuum chamber system is a major challenge.
