Leak testing for electric vehicle manufacturing
The electric vehicle industry is in a period of rapid growth. New products, government regulations and manufacturing standards are constantly evolving. Maintaining the quality of these components and assemblies is of utmost importance - and depends on accurate, reliable testing methods for manufacturing.
When it comes to leak testing, the electric vehicle battery and its components are important elements to test. Once a battery case and/or component is produced, there are many important quality checks that must be performed, including visual weld inspection, assembly checks, dimensional checks, temperature checks and cleanliness checks, but none is perhaps as important as leak testing. The leak test provides the best indication of whether your battery is functioning correctly in the field.

Proven leak testing of electric vehicle batteries and components
Leak testing of electric vehicle batteries and components can be particularly difficult due to the nature of the parts being tested. The environmental conditions, the size of the parts and components, the varying stability of the parts and the sample temperature all present challenges in achieving the required measurement accuracy and repeatability. The most important question when choosing the best leak test method is whether to use air or helium. The goal is to achieve high-quality results - and innomatec helps you achieve this.
The most important question when choosing the best leak test method is whether you want to use air or helium.
Air methods include:
Helium methods include:
Which method is most suitable depends upon your specific application, the part to be tested, the test environment, etc.
