Waterproof Ratings: These vents boast high waterproof ratings, including IP66, IP67, IP68, and IP69K. This signifies their ability to withstand exposure to various levels of water and even to endure high-pressure, high-temperature washdowns.

Breathability: These vents are designed to be breathable, allowing for the passage of air while preventing the ingress of water and contaminants.

Application: These vents are primarily utilized in E-car battery packs and serve the following purposes:

a. Pressure Equalization: They aid in balancing and releasing pressure within the battery pack, thus extending the life of seals and components, especially in the presence of temperature variations.

b. Rapid Valve Opening: The vents are capable of promptly opening in abnormal conditions, such as instances of battery pack overheating, to prevent pressure buildup and potential damage.

c. Condensation Prevention: They help in mitigating condensation within the battery pack, which can have detrimental effects on electronic components.

d. Contaminant Blockage: These vents effectively block contaminants, including dust, dirt, and debris, from infiltrating the battery pack, ensuring that internal components remain clean and fully functional.

e. Cost-Effective Venting Solution: As a cost-effective alternative to traditional breather plugs, these vents offer enhanced functionality and protection.
