Battery Test Chamber

EUCAR (European Council for Automotive R&D) defines seven risk levels (0-6) for rechargeable battery testing. Level 0 = no abnormalities, Level 6 = explosion. Our chambers can be configured with modular safety systems to handle tests up to Level 6, including gas detectors, automatic fire suppression systems, pressure relief valves, and reinforced structures.

We design custom fire suppression systems based on the battery type and the required EUCAR level. Solutions include automatic inert gas extinguishers (argon, nitrogen), sprinkler systems with specialized extinguishing agents, and multiple thermal sensors for rapid activation. There is no one-size-fits-all system for all battery fires—each configuration must be tailored to the chemistry of the battery being tested.

The gas detection system uses specific sensors for H2 (hydrogen), CO (carbon monoxide), and other toxic gases released during thermal runaway. The sensors are connected to the revoFACE controller, which activates warning and alarm levels, can automatically stop tests, activate forced ventilation, or activate fire suppression systems based on the chosen configuration.

The chambers are scalable from 140 to 2300 liters and can accommodate single cells, modules, or complete battery packs of any type: lithium (Li-ion, LiPo, LFP), NiMH, NiCd, lead-acid, and emerging technologies such as solid-state. Internal shelves can be customized based on sample size. We also offer dedicated cable passages for electrical connections during charge/discharge tests, with certified gaskets to maintain airtightness and safety.

Yes, FDM chambers can be configured to meet the requirements of UN38.3 (battery transportation), IEC 62133 (cell and battery safety), UL 1642, UL 2054, and other international standards. The extended climate range (-70°C/+180°C) and precise temperature and humidity control allow for all the tests required by these regulations.

The chamber is designed to safely contain and manage thermal runaway. The reinforced structure resists overpressure, the vent valve releases gas in a controlled manner to external evacuation systems, gas detectors immediately identify the problem, and the fire suppression system intervenes automatically. The controller stops the test and activates all emergency protocols according to the configured EUCAR level.

Yes, the revoFACE controller supports remote control via Ethernet. You can monitor parameters in real time, receive alarms, start/stop tests, and download data from any connected workstation. This is especially useful for extended battery tests or when you want to manage multiple chambers from a central control chamber.

Absolutely. Every battery test has unique requirements. We can customize volumes, EUCAR configurations, fire suppression systems, gas detectors, cable entry, access doors, ATEX compliance, and any other features required for your protocols.

The standard requires transitions between -40°C and +75°C with a minimum hold time of 6 hours per step: the chamber must guarantee constant ramps without overshoot to avoid altering the test results. FDM battery chambers manage complete UN 38.3 cycles automatically via the revoFACEcontroller.

Yes: condensation on terminals and connectors can distort electrical measurements or create unwanted conductive paths. Therefore, relative humidity control (10-98%) is independent of the thermal cycle and can be adjusted to maintain safe conditions at every stage of the test.

We recommend annual thermal mapping verification, in line with IQ/OQ qualification practices: this ensures the traceability of test conditions to certification bodies and auditors. With FDM Care periodic recalibration is planned and documented.
