Services offered at the UL Solutions Europe Advanced Battery Laboratory

Comprehensive battery testing across the product life cycle

Our Aachen laboratory supports battery development from early-stage research and development (R&D) through final product evaluation and market readiness to help reduce technical risk and time to market.

Core testing and evaluation capabilities include:

• Battery safety and performance testing at cell, module and system levels
• Validation under real-world, extreme and misuse conditions
• Assessment of off-gassing, abnormal behavior and thermal events
• Failure analysis, including cell, module and pack teardown to identify root causes and design improvements
• This integrated approach helps advance design optimization earlier and deliver a greater impact on overall product quality and performance.

Advanced battery simulation and lifetime prediction

A key differentiator of the Aachen facility is its ability to estimate battery lifetime and aging behavior using a combination of empirical testing and advanced modeling.

Manufacturers can use these insights to:

• Estimate battery lifespan under multiple duty cycles and operating environments
• Improve durability, reliability and overall safety outcomes
• Support warranty strategies, life cycle assessments and second-life planning
• Leverage Aachen-developed lifetime models and methodologies across UL Solutions’ global battery testing network to support consistent, scalable lifetime assessment programs for international development and production programs

Battery lifetime estimation is increasingly critical as electric vehicle adoption and large-scale energy storage deployments accelerate worldwide.

 

The UL Solutions Europe Advanced Battery Laboratory expands battery lifetime prediction services globally, providing customers with consistent data, methodologies and technical confidence regardless of where batteries are developed, tested or manufactured.

Simulation tools for streamlined battery testing efforts

UL Solutions supports customers across battery manufacturing and research, as well as original equipment manufacturers (OEMs) through the development of software and hardware solutions. We provide software that can help advance more efficient product design, accelerate development and reduce overall costs.

3,000 square meter facility

Can accommodate 500Ah+ cells

Featuring 80 kN to 800 kN press

Customized electronics tailored for battery and battery packs

Some battery and battery pack tests require highly specialized measurement electronics tailored to the specific test parameters. In many cases, commercially available options may not meet the necessary requirements or offer sufficient functionality.

UL Solutions develops custom measurement electronics designed for precise testing needs. Simulating complex, application-specific load cases is essential for algorithm characterization and parameterization. Our experts have experience developing pulse generators that have demonstrated efficacy in these unique scenarios.
