Gas Permeability Tester

Ensuring Material Integrity in the EV Landscape

In the EV industry, maintaining the purity and stability of the battery environment is essential for performance and safety. The gas permeability tester provides a precise way to measure how much oxygen, nitrogen, or other gases pass through materials like battery casings, seals, and protective films. If the rate of gas transmission is too high, moisture and oxygen can infiltrate the battery’s interior, potentially causing corrosion, chemical imbalances, or even early battery failure.

By evaluating the permeability of films, seals, adhesives, and casings used around the battery, engineers ensure these materials maintain the right balance of protection and breathability. If too much moisture or oxygen infiltrates the battery enclosure, it can compromise longevity, safety, and overall performance. Through accurate gas permeability testing, the EV industry can confidently select materials that preserve battery integrity, minimize environmental risks, and enhance the reliability of electric vehicles on the road.

BTY-B3P Gas Permeability Tester

The BTY-B3P Gas Permeability Tester uses the differential pressure method to accurately measure how much gas passes through battery diaphragms, breathable films, and other polymer materials used in EV battery assemblies. In the electric vehicle industry, these insights are critical. By ensuring that only the right amount of gas or moisture can move through these materials, manufacturers can better protect the internal environment of the battery pack. This ultimately leads to more stable battery performance, longer battery life, and a more reliable driving experience for EV owners.
