If a malfunction occurs in an EV battery, rapid venting is required in order to reduce the pressure in the affected battery segment. KACO Sealing Systems has developed a quick deflation solution for EV battery modules, centered around a piston that tightly seals the exhaust port after venting.
KACO’s Quick Deflation is designed so that a pressure compensation element can also be integrated, ensuring both regular pressure compensation and emergency venting in one product. Various locking mechanisms (magnetic and/or spring-loaded) are available to meet customer requirements.
KACO’s VP of R&D Andreas Genesius is enthusiastic about the new solution: “With the development of Quick Deflation for battery systems, KACO offers a further modular product group in the application area of ventilation in the drive train. By using state-of-the-art calculation programs, we can design venting caps and quick vents with regard to closing and opening pressures as well as required flow volumes for specific applications.”
