Short Description

The HERCULES system is a high-performance test reactor designed for comprehensive thermal runaway and abuse testing of lithium-ion batteries. It supports a wide range of trigger mechanisms—such as overcharge, external short circuit, nail penetration, and overheat—under tightly controlled conditions. Capable of operating in adiabatic, inert, or O₂-controlled modes, it enables safe and flexible testing of battery cells, cell stacks, and small modules with in-depth data capture and gas analysis features.

Specifications & Service

  • HERCULES is a dedicated test reactor for simulating and analyzing battery failure scenarios. It is designed for R&D environments where detailed thermal, mechanical, and electrical abuse tests must be conducted safely and precisely.
  • The system supports multiple initiation mechanisms including fast spot heating, nail penetration, overcharge, overheat, and external short circuit. These can be conducted under inert or oxygen-controlled conditions to simulate real-world pack scenarios or worst-case testing.
  • It features an internal reactor volume of approx. 385 L and accommodates battery modules up to 10 kWh. Flexible configuration options allow for integration of up to 100 thermocouples and high-current battery cycling (up to 250 A) for charge/discharge testing during abuse conditions.
  • The system is pressure rated up to 10 bar and equipped with adjustable overpressure valves, hydrogen-safe design, and automated safety checks. A robust drawer mechanism, inspection window, and heavy-duty cable routing simplify day-to-day handling.
  • Operation is semi-automated: test setup is manual, while test execution and monitoring can be fully automated using an optional software suite. The system integrates easily with gas analysis equipment such as GC-MS (Gas Chromatography–Mass Spectrometry) for in-situ sampling and offers real-time data capture on pressure, temperature, voltage, and current.
  • HERCULES is fully CE-compliant and built in Austria to ISO 9001, ISO 14001, and ISO 27001 standards. It is available worldwide with on-site installation, training, and support services.
  • In addition to equipment delivery, 4a engineering provides testing services in Austria, as well as comprehensive simulation and modeling support.
