Learn MoreAchieving a quality seal is critical for the performance, longevity, and protecting components of the battery from water and other harsh environmental conditions. Battery pack seals or gaskets must meet design and regulatory enclosure standards.
The sealing components used also have to be chemically stable toward organic electrolytes. In addition, during the battery's entire service life, the sealing material must not leach out contaminating substances into the battery electrolyte as this could have a long-term negative influence on the cells' electrochemistry.
Let's Talk. Applying a seal – or gasketing - around an electric vehicle (EV) battery pack prevents contamination from environmental hazards and water intrusions.
EVS Battery Pack Sealing Structure Analysis As the output voltage of a pure EVS power battery pack can reach 200V or more, it is essential to ensure that the battery box is properly sealed and waterproof to prevent water ingress and subsequent short circuits. To meet this requirement, the battery box must comply with IP67 standards.
Opening the housing usually destroys the gasket because it sticks to the lid or the housing. This causes battery maintenance problems because in order to seal the housing again, a new lid with sprayed-on gasket is required. This is the reason why large-scale gaskets are used when tough technical requirements need to be met.
