Environmental Chamber for Battery Testing
Control temperature and optional humidity around lithium-ion cells, modules or battery packs while connecting external cyclers, monitoring channels and application-specific safety systems. DERUI configures the chamber around the specimen, heat load, test profile and hazard assessment instead of treating battery testing as a standard climate-chamber application.

What This Battery Environmental Chamber Is Designed to Do
A battery environmental chamber creates a controlled climate around an energized or non-energized specimen. It can support storage, performance, cycle-life and reliability programs in which temperature, humidity, voltage, current and specimen condition must be observed together.
Temperature Performance
Evaluate capacity, resistance, charging behavior and discharge performance at hot, cold or cyclic temperatures.
Climate Exposure
Add humidity control when the test method requires humid-heat exposure, condensation management or enclosure/material evaluation.
Monitored Cycling
Route power, voltage, thermocouple, gas-sampling and communication lines through engineered ports to external test equipment.
Different from the Battery Temperature Test Chamber page: this product is positioned as an integrated climate-and-interface system for batteries. For temperature-only profiles, see the battery temperature test chamber.

Published Configuration and Customization Range
| Published temperature range | -40°C to +80°C in the supplied source content; wider ranges require model-specific confirmation. |
|---|---|
| Humidity | Optional controlled humidity for applicable test profiles. Achievable range depends on temperature, specimen heat load and condensation limits. |
| Inner chamber | 1.2 mm SUS304 stainless-steel plate with welded construction, according to the supplied product information. |
| Exterior | 1.5 mm cold-rolled steel with a coated finish, according to the supplied product information. |
| Thermal insulation | 100 mm mechanically foamed polyurethane, subject to the final configuration. |
| Observation window | Four-layer tempered-glass assembly; size can be adapted to the chamber design. |
| Access ports | Two 100 mm ports were stated in the source specification. Quantity, location and diameter can be engineered for cables, coolant lines and sampling tubes. |
| Control and recording | Programmable climate control with optional data interfaces and remote monitoring, selected to match the project. |
| Workspace and electrical supply | Customized after specimen dimensions, heat dissipation, utility conditions and test method are confirmed. |
Specification note: temperature range alone is not enough to select a battery chamber. Usable performance must be confirmed with the battery mass, active heat load, cable penetrations, ramp-rate definition and safety ventilation operating.
Battery Safety Configuration Should Follow the Hazard
Battery testing can release heat, smoke, flammable gas, electrolyte or pressure. The required safeguards depend on cell chemistry, state of charge, stored energy, test severity and whether the sample is actively charged or discharged.
Pressure and Venting
Configurable pressure-relief device, exhaust connection and make-up-air strategy for the anticipated event and installation site.
Detection and Interlocks
Optional temperature, smoke and selected gas detection with staged alarms, cycler shutdown signals and door interlocks.
Fire-Risk Controls
Optional suppression interface, reinforced viewing design, remote observation and isolation functions based on the customer's safety plan.
Terms such as “explosion-proof” should not be treated as one universal specification. Ask for the exact construction, relief area, detector type, exhaust capacity, interlock logic and suppression boundary included in the quotation.
External Equipment and Feedthrough Planning
The chamber provides the controlled environment; the external cycler, battery management system and measurement instruments provide electrical loading and data capture. Confirm the complete interface before manufacturing.
Electrical Interfaces
- Charge/discharge power cables
- Voltage and current measurement
- BMS/CAN communication
- Emergency-stop and interlock contacts
Thermal and Safety Interfaces
- Thermocouple channels
- Coolant supply and return lines
- Gas-sampling tubes
- Exhaust, drain and suppression connections
Standards: Define the Exact Test, Not Just the Standard Name
Depending on the battery type and market, a project may reference UN Manual of Tests and Criteria subsection 38.3, IEC 62133-2, IEC 62660 series, ISO 12405-4, UL 1642, UL 2054, SAE J2464 or an OEM procedure. These documents address different products and test purposes.
- UN 38.3: transport testing for lithium cells and batteries; confirm the applicable manual revision and amendments.
- IEC 62133-2: safety requirements and tests for portable sealed secondary lithium cells and batteries.
- IEC 62660 series: secondary lithium-ion cells for electric road-vehicle propulsion.
- ISO 12405-4: performance testing for electrically propelled road-vehicle battery packs and systems.
Compliance boundary: a chamber can provide the required environmental conditions, but it does not by itself certify a cell, module or pack. Compliance depends on the complete test setup, calibrated instrumentation, procedure, specimen and acceptance criteria.

Frequently Asked Questions
What is an environmental chamber for battery testing?
It is a controlled enclosure used to expose cells, modules or packs to programmed temperature and optional humidity while external equipment measures or cycles the specimen. Battery-specific versions add engineered feedthroughs, monitoring and safety functions.
How is this page different from a battery temperature test chamber?
The battery temperature chamber page targets temperature-focused testing. This product is positioned for integrated climate testing with humidity options, multiple external interfaces and a project-specific safety system.
Can batteries be charged and discharged inside the chamber?
Yes, when the chamber, feedthroughs, external cycler and safety interlocks are configured for active testing. The maximum electrical and thermal load must be declared before selection.
Is humidity always required for battery testing?
No. Many battery performance and transport procedures are temperature-only. Humidity should be added when required by the test method or when evaluating enclosures, materials, corrosion or humid-heat exposure.
What temperature range should I choose?
Choose the range from the exact procedure and include margin for control under specimen load. The source configuration states -40°C to +80°C, but colder or hotter applications require a confirmed model and refrigeration design.
Does the chamber comply with UN 38.3?
The chamber may provide environmental conditions used in parts of a UN 38.3 test program. It does not alone establish compliance; the complete method, instruments, specimen handling and test report must satisfy the applicable revision.
Which battery safety options are available?
Projects may require pressure relief, exhaust, temperature/smoke/gas detection, remote monitoring, cycler shutdown interlocks and a suppression interface. The final package is selected after a hazard assessment.
Can the chamber be customized for EV packs?
Yes. Workspace, floor loading, door, ports, coolant connections, cable routing, airflow, safety devices and controls can be engineered around the pack and facility. Provide a drawing and maximum heat-load data for review.
Configure the Chamber Around Your Battery Test
Send DERUI the battery format, dimensions, mass, chemistry, state of charge, test profile, heat load, standard clause and required safety concept. The engineering team can then recommend the workspace, climate performance, interfaces and safeguards.
