Targeted Protection for New Energy Vehicles
1. Battery Pack Protection
Vehicle battery packs and enclosures have large internal volumes, making them highly sensitive to temperature variations, pressure buildup, and vacuum effects. These factors can stress sealing components, allowing contaminants to infiltrate—ultimately shortening battery lifespan, degrading performance, and even posing explosion risks.
For non-vacuum sealed components like battery packs and boxes, PUW has developed specialized EPTFE parts with rapid pressure relief, anti-overflow, explosion-proof, waterproof, and dustproof capabilities. During normal operation, they enable efficient air circulation; when internal air pressure reaches critical levels, they instantly release large volumes of gas to the outside, relieving intense pressure and mitigating explosion hazards.
2. Control System Protection
Electronic control units (ECUs) are the core safeguard for safe, reliable vehicle operation. Yet ECUs face extreme temperature fluctuations and harsh working conditions that can severely impair their performance, durability, and safety.
PUW’s waterproof and breathable products for automotive ECUs are rigorously tested to perform under severe external environments and challenging internal ECU conditions. They effectively extend ECU service life and enhance operational reliability in harsh settings.
3. Power System Protection
As demands for motor performance, safety, and comfort continue to rise, components such as wiper motors, starter motors, and water pump motors require robust protection against pollutants, dust, water, and automotive fluids.
PUW’s EPTFE breathable components provide an optimal solution to these challenges, significantly upgrading the performance and durability of automotive power systems.
4. Lighting System Protection
PUW’s waterproof and breathable products for automotive lighting prevent water, automotive fluids, and other contaminants from entering lamp housings. They also reduce fogging caused by temperature and pressure differences while maintaining excellent air permeability.
By choosing PUW’s solutions, automakers can improve the stability of vehicle lighting systems and extend their service life, effectively expelling water vapor and reducing condensation inside lamp assemblies.
