In 2023, SAE International’s Battery Standards Testing Committee, consisting of over 20 companies in EV battery manufacturing and testing, was tasked with recommending practices for evaluating liquid leak-tightness in battery packs.

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.

For lithium-ion traction batteries, leak detection is imperative for battery performance, longevity and safety, especially the prevention of fires.

Leak testing, which has always been essential in the automotive industry for ensuring the manufacture of quality parts and components, is taking on added importance in the mobility age.

Automakers in Europe, the Asia-Pacific region and the United States are struggling with performance and safety issues associated with electric and hybrid-electric cars.

Electromobility is currently one of the most significant trends worldwide, and it is destined to change the way people purchase vehicles, travel and enjoy their leisure time. 

When it comes to the production of automobiles, trucks, heavy-duty equipment, off-road vehicles and farm equipment, early detection and resolution of even the smallest leaks are key to minimizing recall-related expenses.

The smallest leak in a component or sub-assembly can compromise a product’s performance and ultimately your company’s reputation.
