Lithium-ion batteries are playing an increasingly important role in the growth and evolution of electric and hybrid vehicles in the automotive industry. Currently battery packs are the heaviest and most expensive component in electric vehicles, but the industry is moving to lighter weight options. Adequate venting is necessary for any battery pack as it helps regulate temperature and pressure fluctuations. Proper venting also provides protection against the ingress of contaminants from harsh external conditions and can extend the life and performance of the battery pack.
Dual-stage venting has proven to be a flexible and effective method for venting automotive battery packs. With dual-stage venting, the first stage equalizes pressure while preventing the ingress of water and contaminants in normal vehicle usage. Stage two is activated in a thermal runaway situation. The vent fully opens to quickly release pressure and heat buildup from within the battery pack and allow expanding gases to escape and prevent further damage to remaining cells.
