Thermal & Chemical Test Methods

Thermal testing to identify hotspots, coolingrequirements, and potential thermal risks.

What we Do

Temperature is one of the most critical factors influencing battery safety, performance, and lifetime. Thermal imbalances or uncontrolled heat generation can accelerate aging and in theworst case trigger thermal runaway. Our thermal and chemical testing methods analyze heat generation, propagation behavior, and gas emissions underrealistic and extreme conditions. These insights help manufacturers design effective cooling strategies, mitigate safety risks, and ensure stable batteryoperation even under demanding conditions.

Thermal TEst

Thermal Propagation

Induction of thermal runaway in a single cell to demonstrate propagation prevention at module or pack level.

Insights: Evaluates whether thermal runaway spreads within a battery system and validates mitigation concepts.

THERMAL TEST

Overheating

Exposure oftest specimens to critical ambient temperatures to determine thermal stabilitylimits.

Insights: Identifies temperature thresholds that may lead to critical material or separator failure.

THERMAL TEST

Gas Emission Analysis

Qualitative and quantitative analysis of venting gases released under fault conditions.

Insights: Determines composition, toxicity, and flammability of emitted gases for safety assessment.

THERMAL TEST

Cell and Pack Material Testing for Heat Dissipation

Validation of thermal interface materials (TIMs) and cooling strategies.

Insights: Supports optimized thermal management and improved battery lifetime.

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.
