What is battery pack testing?

Battery pack testing evaluates the overall performance and safety of a complete battery system, often subjecting it to rigorous conditions to simulate real-world usage. Test scenarios for pack testing in the lab includes: Environmental Testing - Evaluating performance in extreme temperatures, humidity, and altitude.

Why is battery pack & module testing so important?

Battery pack and module testing is more critical than ever. Today’s engineers face new challenges including increased complexity of the tests and set-ups, long development and test times, addressing safety requirements, and avoiding hazards.

Why do batteries need to be tested at a pack level?

At the heart of testing battery cells, modules and packs are the levels of voltage and current. Temperature and pressure are increasingly important conditions to test at the pack level, while improving the underlying accuracy of the fundamental measurements is naturally a key trend.

How do engineers test a battery pack?

Engineers also check for any malfunction, temperature rise in the battery pack, current carrying capacity, cooling capacity, and overall mechanical structure. After complete testing, packs may undergo extra testing to simulate the typical conditions and be integrated into the system or end-product.

How can we reduce the test time of battery packs?

Many different materials, and combinations of them, are being investigated, and they need to be tested over many thousands of hours. That creates a significant test challenge. New test techniques, modular test systems and techniques for modelling the battery performance are all helping to reduce the test time of battery packs.

What is a battery test?
