Case Study The Volkswagen Group has consolidated the development and pre-series production of high-voltage battery systems at the Battery Systems Competence Centre in Braunschweig. This requires extensive testing capacities for temperature and climate tests. To maximize space efficiency, 22 identical test chambers will be installed in the hall. Three of the chambers will be designed for temperature tests at higher temperatures and one for temperature cycling tests with an increased rate of change. The chambers must provide space for complete lithium-ion packs. Because the tests are carried out on energized batteries, sophisticated safety equipment according to EUCAR Hazard Level 6 is required to protect both personnel and the system. A basic design concept was developed and implemented across all 22 test chambers. To minimize the footprint, the test chambers were mounted on a base frame with the machine components positioned underneath. For safety, each test chamber is installed in a ceiling-high enclosure to prevent potential incidents from affecting personnel and other testing equipment in the hall. To meet EUCAR Hazard Level 6 standards, the safety equipment must protect against electrolyte and gas leaks, fires, and flying test fragments during overloads or malfunctions. Extensive protective measures were implemented for this purpose.

Case Study Weiss Technik realizes 22 test chambers for testing Li-ion batteries WHAT | The solution. Twenty-two climate test chambers with features for Hazard Level 6 Twenty-two climate test chambers with features for Hazard Level 6. The system consists of 22 compact test chambers for temperature and climate tests with a machine section underneath the test chamber. The dimensions of each test chamber are 3,350 × 3,100 × 3,000 mm (W × D × H). The test space is 6.8 m³. The maximum test specimen weight is 1,200 kg. Half of the chambers are fitted with a two-level test rack, thereby, allowing smaller...
