The TestEQ battery test chamber provides controlled temperature and optional humidity environments for lithium-ion cells, modules and battery packs. It supports the environmental parts of battery qualification — thermal cycling, temperature exposure and combined climate testing — and can be paired with TestEQ altitude, thermal shock and vibration systems to cover a full UN38.3 test program.

The required chamber configuration depends on the battery type, test method and qualification program; chamber size and fixtures are customised accordingly.
UN38.3 test coverage
UN38.3 (Section 38.3 of the United Nations Manual of Tests and Criteria) defines eight procedures for lithium battery transport safety. TestEQ provides the environmental equipment for several of them:
- T1 Altitude Simulation — altitude test chamber for low-pressure conditions equivalent to high-altitude air transport.
- T2 Thermal Test — temperature chamber or thermal cycling chamber for repeated high- and low-temperature exposure.
- T3 Vibration Test — vibration and transportation simulation systems.
- T4 Shock Test — mechanical shock systems, with customised solutions for large battery packs.
- T5 External Short Circuit, T6 Impact and Crush, T7 Overcharge, T8 Forced Discharge — electrical and mechanical abuse test setups.
Standards
Chambers support UN38.3 testing and can be configured to related reliability requirements including IEC 60068 and IEC 62133. Technical resources: Thermal Shock Test Chamber , Altitude (Low-pressure) Test Chamber , Temperature Humidity Test Chamber , Temperature Humidity Vibration Test Chamber .
