Mechanical testing – battery testing

What is mechanical testing of batteries?

Mechanical testing includes both static and dynamic testing of batteries, battery cases, and related components. The test consists of, for example, a tensile test, pressure test, fatigue test, impact test, creep test, and internal pressurization of batteries.

Examples of mechanical impact on batteries

The mechanical impact is investigated during (or after) batteries, battery cases, and their components have been exposed to various types of impacts. The impacts include internal damage, short circuits, electrolyte leakage, and structural damage. These can all have serious consequences.

Why is mechanical testing of batteries carried out?

Mechanical testing is important from a safety aspect. If the battery, battery case, or its components are not suitable for their intended use it may lead to reduced capacity, reduced efficiency, reduced performance, or overheating of the battery. There is also a risk of fire and explosion – in other words, a risk of serious injury.

Increased electrification requires more testing

Investigating mechanical risks is becoming increasingly important as electrification in society increases, not least with an increased number of electric vehicles. Mechanical testing is necessary to ensure product safety and is therefore important for producers and importers, as well as retailers.

You will receive guidance on mechanical testing

We help you with the mechanical testing of batteries in our laboratories. We keep track of the latest regulatory changes and provide guidance on requirements and standards.  By taking the help of RISE, you also get access to our entire institute's collective expertise, competence, and experience. In the battery area, we operate in materials, chemistry, energy, analysis, and certification.

We offer both standardized and unique testing

Our experience in mechanical testing accompanied by an extensive machine park and modern lab resources enable great flexibility and unique testing possibilities. Thinking outside the box is our everyday life! In addition to mechanical testing for force, deformation, pressure, and elongation, we offer advanced measurement methods, such as Digital Image Correlation (DIC), Digital Volume Correlation (DVC), and acoustic emission (AE).

Combination of different types of testing

With our possibilities for safety-critical testing, we can also combine mechanical testing with, for example, cycling batteries. If a battery ends up in thermal runaway or propagation, we can measure heat generation, emissions of gases, and more. At RISE, you get help with the right combination of tests.

Deliveries

As a client, you will receive a digitally signed technical report with your test results. You will receive the report in Swedish or English, whichever you prefer.
