Multi-Axis Vibration Test Chambers for Large-Format Cells Safety Test

Our Multi-Axis Vibration Test Chambers are the ultimate specialized platform for the comprehensive safety and durability validation of Large-Format Battery Cells (prismatic, pouch, and cylindrical). This integrated system uniquely combines multi-directional dynamic testing (X, Y, and Z axes) with a high-performance climatic chamber, all within a secure, safety-certified environment. By accurately simulating the complex mechanical and thermal stresses that can lead to catastrophic failures, our chambers are indispensable for validating the structural integrity, electrical isolation, and safety of the next generation of EV and ESS cells.

Key Features

• True Multi-Axis Vibration Capability: Our system allows for complex testing along the X, Y, and Z axes, either sequentially or simultaneously. This is critical for reproducing real-world vehicle maneuvers, battery pack structural stresses, and accurate simulation of seismic events on ESS units.

• Integrated Advanced Safety Protocols: Safety is the primary focus. The chamber includes essential features for testing large-format cells:

  • Inert Gas Purging: Automated injection of inert gas (e.g., Nitrogen) to rapidly suppress fire or prevent thermal runaway spread.

  • Explosion/Pressure Relief: Reinforced chamber construction with pressure venting mechanisms.

  • High-Voltage Isolation: Continuous monitoring and secure routing for high-current leads.

  • Dedicated Fire Suppression: Integrated, automatic fire detection and extinguishing system.

• Precision Climatic Control: The chamber maintains tight control over temperature (e.g., from $-70^circ C$ to $+180^circ C$) and humidity, allowing for the study of structural failure under thermal extremes.

• Large-Format Cell Fixturing: The chamber and shaker interface are designed with flexible, high-rigidity fixturing to securely mount multiple large cells or modules for testing without distortion.

• High-Fidelity Vibration Control: Provides accurate, repeatable generation of sine, random, and shock profiles, ensuring mechanical stress is applied exactly according to specification.

• Comprehensive Data Acquisition: Continuously monitors and records all environmental parameters, multi-axis dynamic data, and critical cell data (voltage, current, thermal data) for synchronized failure analysis.

Applications

• Thermal Runaway Propagation Studies: Investigating how multi-directional mechanical stress affects cell stability and the spread of thermal runaway events.

• Structural Integrity Validation: Testing the integrity of cell casing, welding, and internal structure under combined mechanical fatigue and thermal cycling.

• Internal Short Circuit Prevention: Subjecting cells to combined stress to proactively identify conditions that could lead to internal shorts and catastrophic failure.

• Regulatory Compliance: Providing the necessary multi-axis, environmental, and safety data for compliance with standards like UN 38.3 and regional EV/ESS safety mandates.

• R&D and Failure Analysis: Accelerating the validation of new cell chemistries and formats by rigorously stress-testing them to identify safety margins.

Benefits

• Unmatched Risk Mitigation: The integrated safety suite provides the highest level of protection, allowing R&D teams to safely push cell limits.

• Superior Test Realism: Multi-axis testing combined with climatic stress provides the most accurate replication of real-world failures, which single-axis testing often misses.

• Accelerated Safety Discovery: Rapidly uncovers critical safety flaws and structural weaknesses early in the design phase, preventing costly recalls.

• High-Quality Data: Generates synchronized, auditable data essential for scientific analysis and achieving necessary safety certifications.
