Why is a battery leak test important?

In summary, leak testing individual components of a battery system, and complete battery assemblies and housings is a critical step in the development of electric vehicles. It contributes to ensuring the reliability and safety of these vehicles, enabling consumers to fully realize the benefits of electromobility.

How do you conduct a battery leak test?

Fundamental Approach to Contacting: Selecting appropriate contact methods is crucial for conducting leak testing effectively and accurately. Utilizing the Later Electrical Interfaces: A proven approach is to use the existing electrical interfaces of the batteries for testing. This minimizes the effort and increases efficiency.

Why is leak testing important for electric vehicles?

Leak testing battery cells and housings requires specialized methods and adaptation to individual requirements. Despite the lack of standardization in the industry, the mentioned approaches and techniques are crucial to ensuring the safety and reliability of electric vehicles.

Why is battery leak testing so difficult?

Battery Housings: Battery housings typically need to have a substantial volume to achieve the required energy density as well as the capacity for the demands of electric vehicles. This means that the volumes of battery housings can be considerable, making leak testing more complex.

What is lithium-ion battery leak-detection?

This breakthrough leak-detection technology for all types of lithium-ion battery cells represents the single most important leak-detection development in the past 10 years, not just for the automotive industry but for the makers of smart phones, computers, consumer-electronics products and a variety of medical devices as well.

How reliable are leak-detection tests?

There currently are no reliable tests on which to base leak-detection standards for a full range of soft-pouch, cylindrical or prismatic cells in use throughout the industry. Pressure, helium-bombing and visual testing methods used up until now are either too slow or unreliable and may allow small but significant lithium-ion leaks to go unnoticed.
