Comprehensive battery capacity and life tests of battery packs, cells and modules
TÜV SÜD provides professional battery pack, module and cell performance testing, in our global network of state-of-the-art battery testing laboratories to deliver answers to those questions. Our laboratories create precise simulation of electrical, thermal or climatic loads and other conditions that your batteries may be exposed to in real-life use. As an expert in battery performance testing, we can support you throughout the development and manufacturing process to optimise the capacity, reliability and safety of battery packs, cells and modules.
How do external conditions affect battery cells, modules and packs? What factors impact their capacity and lifetime? Which environmental conditions accelerate ageing? These are the questions addressed by battery performance testing.
Battery performance testing describes electrical testing of battery packs, modules and cells, superimposed by thermal and climate conditioning. By simulating a range of external influences in special testing chambers – such as climatic conditions including arctic temperatures and humid tropical climates – evidence can be collected to the impact of these conditions on your battery; e.g. the impact of mechanical stresses caused by thermal or electrical loads.
At the same time cooling units simulate the cooling cycle. Extensive measurement and simulation equipment further allow the recording of electrical and climatic data as well as simulation and recording of communication between batteries and control devices.
Batteries have become essential parts of our everyday life. The wide use of batteries across industries renders battery pack testing as well as battery cell and module testing essential for the safety of users. And as electric vehicles become more popular, so will the need for electric vehicle battery safety. Conducting life cycle and capacity tests is one crucial step towards validating battery safety and durability.
