Leak testing of EV battery cells and modules is vital for safety and defect prevention in North America's growing mobility industry. Early detection of leaks, especially during module assembly, saves time and money while ensuring quality control.
This article is designed to assist people that test for leaks using air in industrial quality control and want to learn how they can determine a leak test specification beyond zero leaks.
Leak testing is an important quality control measure in manufacturing. This article provides guidance on determining leak testing specifications by exploring factors and modifying existing specifications or creating new ones.
With pumping speeds ranging from 80 to 800 liters per second, the HiCube Neo vacuum pumping station is ideal for demanding high vacuum and ultra-high vacuum applications.
Plant engineers and quality departments often struggle with zero point drift during air leak testing, where the initial zero reading shifts over time, leading to frequent adjustments of the leak test instrument. This article addresses the causes of zero drift, commonly attributed to changes in shop floor temperature, and provides strategies to minimize or eliminate this issue for improved efficiency in quality control processes.
Some manufacturers will use a single-point calibration system to measure volumetric flow—however, a two-point calibration provides a much higher level of accuracy.
Manufacturers that routinely challenge their leak tightness testing process will consistently produce products with reliable performance, battery longevity and safety.
