What Green Testing Lab does
Green Testing Lab GmbH is an Austrian battery abuse testing laboratory founded in 2020 by Max Hofer and headquartered in Greinbach (Hartberg region, Styria). The company's stated mission is to make e-mobility safer through specialized destructive testing of lithium-ion battery cells, modules, and packs under extreme conditions. Core infrastructure consists of two proprietary abuse test chambers — AC01 (designed for batteries up to 120 kWh, 1200 kg) and the newly launched AC02 (up to 250 kWh, 2000 kg, with climate conditioning, multiple extinguishing systems, and ISO 26262 support) — supported by purpose-built test rigs including a Heating Dummy Cell trigger method that delivers 100% reproducible cylindrical cell triggering, a 30 kA short-circuit test system, a 2000 kg / 5-second immersion system, a hydraulic crush rig rated to 300 kN, and a Venting Gas Breakdown Voltage Tester. The technology stack supports standardized protocols including UN/ECE-R100, SAE J2464, SAE J2929, ISO 12405, IEC 62660, UL 2580, ISO 26262, and Freedom CAR.
Revenue is generated through two professional services streams: fee-for-service abuse testing (thermal propagation, nail penetration, crush, drop, immersion, short circuit, fire resistance, and cell-level abuse programs) and custom test rig development for customers with proprietary requirements. Pricing is custom-quoted in EUR with multi-year contract cadences and tiered cancellation policies; go-to-market is exclusively direct enterprise sales targeting automotive OEMs, battery cell manufacturers, development service providers, and heavy-duty commercial vehicle manufacturers. A Remote Test Control System differentiates the offering by enabling customers to monitor live tests from any location.
The company operates the annual Battery Safety Talk conference in cooperation with ACstyria Mobilitätscluster and VIRTUAL VEHICLE Research, launched the Green Testing Lab Innovation Award in 2025, and is integrated into the European battery R&D ecosystem via strategic partnerships with AVL List GmbH, CSM Computer-Systeme-Messtechnik, and a Glass Battery research consortium with Magna Steyr, Kreisel Electric, and TU Graz. As of 2025, Green Testing Lab employs approximately 14 people and remains entirely founder-owned with no disclosed venture capital or institutional investor participation; facility construction in 2023 was co-financed by the European Regional Development Fund (EFRE) and REACT-EU.
