Electrical Battery Testing

Comprehensive characterization of electrical performance and validation against electrical fault conditions.

What we Do

Our Electrical Test Methods are designed to push battery cells to their limits, ensuring they remain stable under extreme operational stress. By simulating real-world electrical fault conditions and characterizing core performance metrics, we provide the data-driven confidence needed for integration into demanding automotive and industrial applications.

Testing how the cell behaves in dangerous "worst-case" scenarios

Safety & Fault Tolerance Testing

Overcharge Resilience

Charging beyond the upper voltage limit to evaluate electrochemicalstability and the reliability of cutoff and protection devices.

Insights: Short statement describing the key outcome of the test.

Deep Discharge Recovery

Discharge below the specified voltage limit to analyze degradationeffects and risks associated with recharging.

Insights: Short statement describing the key outcome of the test.

External Short Circuit (ESC)

Simulation of external short circuits to assess current-carryingcapability of cell tabs and thermal response behavior.

Insights: Short statement describing the key outcome of the test.

Performance Testing

High-Power Performance Mapping

Determination of key parameters (HPC, HPPC, OCV, SOH) and execution of customized test profiles with currents up to 1,000 A across a voltage range from 0 to 6 V.The Goal: Establishing the "standard of truth" for cell efficiency.

Our Goal: Provide a high-resolution map of internal resistance (DCIR) across the full operating range, essential for accurate thermal modeling and range estimation.

Lifecycle & Prototype Development

From initial formation to long-term aging.

Lifetime testing under defined climatic conditions. Determining cycle life and aging behavior through continuous electrical stress within controlled environments.

Our Goal: Determine the SOH (State of Health) degradation slope, allowing for accurate prediction of "second-life" battery potential.

Prototype Development

Perfecting the chemical foundation of new cells.

Execution of formation processes for prototype cells and quality assessment of the solid electrolyte interphase (SEI). This is the most critical step in a cell's life, as it defines its future stability.

Insights: Optimizes the initial SEI layer formation to maximize long-term stability and minimize initial capacity loss during the first 50 cycles.

Advanced Electrochemical Diagnostics

Seeing inside the cell without a single incision.

Electrochemical Impedance Spectroscopy (EIS) Non-destructive, frequency-dependent analysis of internal resistance for detailed investigation of electrochemical processes and aging state.

How it works: By "listening" to the cell at different frequencies, we can separate chemical reactions from physical resistance.

Insights: Detects early-stage lithium plating and electrode degradation before they are visible in standard capacity or voltage tests.

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.
