Battery performance testing

Battery performance analysis and battery life cycle testing evaluates the performance, safety, and durability of battery cells, modules, and packs. Using special testing chambers, TÜV SÜD simulates real-life conditions and stresses that batteries might encounter during usage.

Rigorous battery performance testing is vital to meet high reliability and performance standards as the demand for electric vehicles and other battery-powered devices grows. Battery life cycle testing and capacity tests are a crucial step in validating safety and durability, ensuring batteries perform consistently under varying environmental conditions. Test data also helps to improve battery design and enhance overall battery performance.

Comprehensive testing helps manufacturers to achieve better product quality, reduce the risk of failures, and demonstrate compliance with stringent international and industry-specific standards. This delivers faster market access and enhanced consumer trust.

TÜV SÜD has decades of battery testing experience and a deep understanding of the latest technologies. Our advanced testing capabilities use cutting-edge facilities that simulate a wide range of environmental and operational conditions. Customised testing solutions deliver tailored testing programmes that meet your specific needs, from R&D to final product validation. Our detailed reporting and battery performance analysis provides insights and actionable recommendations to ensure your products comply with global standards.

TÜV SÜD offers state-of-the-art battery performance testing services that include electrical, thermal, and mechanical tests. We help you to optimise battery products for better performance and safety.

Our battery performance tests cover:

• Battery cell, module, and pack testing of all formats and types, and several ranges of measurement:
• Testing of cyclic and calendric ageing, and of ageing effects caused by realistic driving profiles.
• Battery capacity test and pulse power test.
• Electrical characterisation (e.g. internal resistance /SOC) and electrical tests with parallel thermal tests (-40°C to 80°C).
• SOC/OCV determination benchmark tests of rapid charging profiles.
• Automated evaluation of measured data with customer-specific, scalable reporting.
• Fast charging, power capability and PTCE (Power and Thermal Cycling Endurance) tests.

Complementary battery cell, module and pack services:

• Cycling with cooling systems.
• Parallel mechanical loading using a uniaxial vibration test system.
• Measurement of volume-change effects in cells and modules.
• Single cell voltage measurement on modules.
• Module balancing.
• Electrochemical impedance spectroscopy (0-20V +/- 10A).
