High-Frequency Vibration System with 3m x 3m Table for Battery Subpacks and Large EV Modules

Product Description:

Our High-Frequency Vibration System featuring an expansive 3 meter by 3 meter (3m x 3m) table is specifically engineered for the critical testing of large-format Battery Subpacks, EV Modules, and full-sized assemblies. This powerful, customized solution provides the necessary high-frequency performance and vast test surface area required for simultaneously testing multiple components or very large, complex structures used in the electric vehicle (EV) and energy storage sectors.

Key Features:

• Extra-Large 3m x 3m Test Table:

  • Maximum Payload Area: Provides an industry-leading surface area for mounting multiple battery modules or testing single, oversized subpacks.

  • High Stiffness and Flatness: Engineered with lightweight, high-st-iffness magnesium or aluminum alloy to ensure minimal modal deformation and uniform vibration transfer across the entire large surface.

• High-Frequency Performance:

  • Designed to maintain high acceleration and velocity across a broad frequency range, crucial for simulating the structural fatigue and failure modes of battery components.

  • Ideal for capturing high-frequency inputs from road noise, motor whine, and internal cellular resonance.

• High-Force, Water-Cooled Shaker:

  • Utilizes a robust water-cooled electrodynamic shaker (or multiple shakers) to deliver the sustained high force required to drive large, heavy payloads at high frequencies for extended periods (e.g., long-duration fatigue testing).

  • Ensures thermal stability and reliability during demanding test cycles.

• Superior Control and Uniformity:

  • Multi-Point Control: Advanced digital controller supports multiple accelerometers placed across the large table to monitor and maintain vibration uniformity (phase and amplitude) across the entire 9 $m^2$ area.

  • Waveform Versatility: Capable of generating high-fidelity Random, Sine, and Classical Shock waveforms required by automotive and regulatory standards (e.g., UN/ECE, SAE).

• Battery Safety Integration:

  • Includes enhanced safety interlocks, high-voltage isolation, and thermal monitoring interfaces tailored for testing live battery components.

Applications:

• EV Battery Module Qualification: Simultaneous testing of multiple modules or comprehensive testing of large subpacks for durability.

• Battery Thermal Systems: Evaluating the structural integrity of cooling plates, manifolds, and enclosures under vibration.

• Large Component Fatigue: Durability and reliability testing of other oversized automotive or aerospace assemblies.

• Simultaneous Testing: Maximizing lab throughput by testing multiple smaller battery units at once.

Benefits:

• Maximized Throughput: The large table significantly increases test efficiency and laboratory productivity.

• Accurate Simulation: High-frequency capability allows for realistic simulation of operational wear and tear.

• Regulatory Confidence: Provides the high-fidelity, uniform data required for critical safety and compliance documentation.

• Future-Proof: Accommodates the increasing size and weight of next-generation EV battery architecture.
