Focusing Technologies on Battery Testing

In an industry shaped by rapid innovation, regulatory pressure, and growing safety concerns, the demands on battery testing have never been higher. Whether you're developing next-generation battery systems for e-mobility, testing modules before shipment, or evaluating the residual performance of second-life storage systems — advanced environmental testing is essential for ensuring long-term performance, functional safety, and market approval.

From R&D labs to end-of-line testing and second-life qualification, batteries are subjected to a wide range of environmental conditions. Thermal stress, vibration, humidity, and mechanical shock can all influence the integrity, lifespan, and safety of a battery system. The risk of fire, thermal runaway, and explosive events must be assessed and mitigated through reliable, controlled, and repeatable testing protocols.

As energy density increases, so do the hazards. That’s why the EUCAR Hazard Levels and ATEX guidlines play an important role in defining safety requirements in battery testing environments. Especially when testing large-format lithium-ion batteries or complete battery packs, selecting the right test infrastructure is about more than performance — it’s about protecting your product, your people, and your lab environment.

Weiss Technik is one of the world’s leading providers of climate, temperature, vibration and more environmental test systems. We offer battery testing solutions that meet the most demanding industrial and regulatory requirements. Backed by decades of experience in battery testing, we offer manufacturers, suppliers and external test laboratories customized solutions for the entire life cycle of batteries..

Whether it is a single test chamber, a complete lab or a container-based solution, we know what matters. We take your infrastructure, your testing requirements and all safety-relevant aspects into account and support you from concept to commissioning. After installation, our service team is also there for you with fast and reliable support for maintenance and calibration.

Experience how our customer FEV brings battery testing to life. From environmental and mechanical stress tests to performance testing of battery cells, modules, and packs – this facility demonstrates the full range of possibilities enabled by Weiss Technik systems. With test temperatures from –40 °C to +90 °C and powered largely by a 12,000 m² photovoltaic system, it sets new standards in both capability and sustainability.

Compliant battery testing

A wide range of standards and test specifications define the type of tests that must be carried out on batteries. In order to achieve reliably comparable results at all times, the prerequisites and the test procedure are precisely defined. We support you in the planning and implementation of a tailor-made solution for your testing task. Of course, we adhere to all relevant standards and specifications and advise you in detail if required.

Battery tests determined according to international standards include tests in the areas of environmental stress, electricity, mechanical stress and performance/ageing.
