Mechanical Test Methods

Simulation of cell behaviour at real-worldaccident scenarios to
assess cell reactions and structural limits

What we Do

Mechanical stresses are unavoidable in real-worldbattery applications. Vibrations, compression forces, and crash events cancompromise structural integrity and trigger critical failure mechanisms. Ourmechanical testing methods replicate these conditions in a controlled environment to evaluate cell behavior, identify structural limits, and validatesafety concepts. The result: reliable insights that help manufacturers designbattery systems that remain robust and safe throughout their entire lifecycle.

MECHANICAL TEST

Dynamic Deformation

Simulation of crash scenarios through sudden forceapplication to assess fail-safe behavior and enclosure integrity.

Insights: Reveals how cells and housings respond to suddenmechanical loads and helps evaluate safety mechanisms under crash conditions.

MECHANICAL TEST

Nail Penetration

Targeted initiation of an internal short circuit toanalyze thermal response and validate safety mechanisms against thermalpropagation.

Insights: Demonstrates cell reaction to internal shortcircuits and helps assess risks of thermal runaway initiation.

MECHANICAL TEST

Quasi-Static Deformation

Slow compressive loading to determinemechanical load limits and deformation behavior of the cell structure.

Insights: Defines structural limits and helps determine safemechanical integration conditions.

MECHANICAL TEST

Customer-Specific Mounting Analysis

Investigation of the effects of clamping forces and assembly tolerances on cell performance to optimize module integration.

Insights: Supports optimized module design by understandingthe influence of mounting conditions on cell behavior.

FAQ

Find answers to your most pressing questions about battery testing services.

Why is battery testing so critical in development?

Comprehensive testing is the only way to verify the safety, performance, and lifetime of a battery. PEM Motion provides tailored test programs designed to meet the specific requirements of both prototype and series production projects.

What types of tests does PEM Motion offer?

We conduct electrical, mechanical, thermal, and safety-related tests. This includes cycle life testing, fast-charging tests, abuse testing, and thermal management evaluations.

Does PEM Motion also support the interpretation of test results?

Yes. Our experts help analyze test data and translate it into actionable recommendations. This not only saves valuable development time but also reduces unnecessary design iterations.

How quickly can tests be carried out?

Timelines depend on the type of test. Thanks to our flexible laboratory infrastructure and strong partner network, PEM Motion can typically achieve very short lead times. We will always find a good solution, if there are time-critical projects.

What role does testing play in series production?

Beyond development, testing is essential in production – for example, during end-of-line inspections. PEM Motion supports the implementation of efficient testing processes directly into manufacturing workflows.
