Walk-In Battery Pack Test Chamber

Battery pack testing requires more than a larger chamber volume. Engineers also need sample access, floor loading, cable routing, monitoring space and stable environmental control during long-duration tests.

The walk-in structure allows users to test EV battery packs, ESS modules and BESS battery systems under controlled temperature and humidity conditions while keeping enough working space for fixtures and test instruments.

• •Suitable for EV, ESS and BESS battery pack testing.
• •Walk-in structure for large and heavy samples.
• •Custom inner dimensions based on battery size and site layout.
• •Stable temperature and humidity simulation for pack-level testing.
• •Compatible with charge-discharge test equipment.
• •Suitable for R&D validation, reliability testing and production quality control.

This battery climatic test chamber simulates controlled environmental conditions to evaluate battery pack performance, safety and reliability under different operating, storage and transportation scenarios.

• •EV battery pack high and low temperature testing.
• •ESS and BESS battery thermal cycling tests.
• •Battery pack temperature humidity testing.
• •Long-term storage and aging tests.
• •Charge-discharge cycling under controlled temperature conditions.
• •Battery pack reliability and durability validation.
• •New energy vehicle component environmental testing.
• •Battery manufacturing quality control.

The chamber helps engineering teams understand how battery packs perform under cold, heat, humidity and repeated environmental stress before mass production or field deployment.

Large battery packs carry higher energy and require safety systems matched to the test risk level. Sanwood Walk-In Battery Pack Test Chamber can be configured for lithium battery safety and abuse test scenarios referenced to EUCAR hazard level (0-7), depending on sample energy, battery chemistry, test method and laboratory safety requirements.

The chamber can support environmental testing, abuse testing and thermal runaway-related test conditions when equipped with the appropriate safety configuration.

• •Explosion-proof chamber structure.
• •Pressure relief design.
• •Smoke exhaust system.
• •Fire suppression interface or system option.
• •Gas detection option.
• •Emergency stop system.
• •Door lock and safety interlock.
• •Over-temperature and abnormal operation alarm.
• •Remote monitoring option.
• •Safety configuration for EUCAR hazard level (0-7) related test scenarios.

Final safety configuration must be confirmed according to battery capacity, target EUCAR hazard level, test procedure, site layout and local safety requirements.

The chamber uses a programmable control system for temperature, humidity, test profiles, alarms and optional data recording. Engineers can set multi-step programs for heating, cooling, constant temperature, humidity control and cycling tests.

For large battery packs, airflow design is especially important. Sanwood can adjust air duct layout, refrigeration capacity and sensor placement according to chamber volume, battery heat load and test requirements.

• •Programmable touchscreen controller.
• •Temperature and humidity control.
• •Multi-step test profile setting.
• •RS232, RS485 or Ethernet communication optional.
• •Optional PC monitoring and data logging.
• •Optimized airflow for large chamber uniformity.
• •Stable refrigeration system for long-duration testing.
• •Modular refrigeration design for easier maintenance.

Sanwood Walk-In Battery Pack Test Chamber can be configured to support test conditions related to common lithium battery environmental and safety test methods, including IEC 62660, IEC 62619, IEC 62133, IEC 60068, UN 38.3, SAE J2464, SAE J2929 and UL 1642.

Walk-in battery test chambers are usually project-based systems. Sanwood can customize chamber size, temperature range, humidity range, floor load, safety configuration, door structure, cable ports, observation windows, refrigeration layout and power supply according to the customer's test plan and installation site.
