Testing high-power electric vehicle (EV) battery packs requires emulation of its operating environment. Learn how to use analysis, emulation, and electrochemical impedance spectroscopy to ensure optimal real-world performance of high-power EV battery packs.
The Keysight high-power EV battery pack test solution enables battery development and validation. The solution covers output power up to 300 kW and voltage up to 1500 V. High-voltage silicon carbide (SiC) technology provides high energy efficiency on a small footprint and helps minimize operating costs.
Below are two of the key challenges you are likely to encounter with battery pack leak testing and strategies to overcome them. Any kind of test that builds pressure (with air) inside the pack can cause the volume to expand like a balloon, which will increase the measured leak rate.
Dynamic impact tests can be conducted using two different test methods: The moving impactor hits the battery attached to a rigid barrier. The moving battery hits an impactor attached to a rigid barrier to expose the battery, including the battery management system, to real deceleration.
TÜV SÜD can perform dynamic impact tests for electric vehicle batteries and provide advice on the optimum test design. We have a modern, fully equipped crash testing facility staffed by a dedicated team of automotive and battery experts who collaborate with you to support your development needs.
To ensure that the battery is as safe as a conventional fuel tank, it is necessary to test electric vehicle batteries by modelling the actual conditions of a crash that may cause major deformation of the battery. The tests are conducted at our crash test facility, which utilizes impactors with variable mass and geometry.
