        Battery Anti-Explosion Vent

        As mobility is changing to electric and hybrid vehicles, battery systems are acquiring a leading role in the mobility industry. To power these vehicles, rechargeable batteries are arranged in modules and packs offering a high ratio of energy per unit volume. These new battery systems need robust protection from harsh external contaminants such as water, dirt and oil, along with adequate venting to compensate the pressure differences between the interior of the storage unit and the external environment.

        To improve battery systems life and increase their safety, GVS has developed specific Battery Anti-Explosion Vents. These devices have two integrated functions. First, they guarantee adequate pressure equalization and protection against the entrance of external contaminants, such as oil, water and dust, during normal operating conditions. In addition, thanks to a patented GVS design, they guarantee fast gas evacuation during a thermal runaway event, without affecting the functionalities of the membrane which keeps its integrity. Therefore, it is a dual-stage solution valve that prevents the damage of the battery housing and enables a quick restoration of controlled pressure equalization.
