Standard

  • UL 1642: Standard for Lithium Batteries
  • IEC 62660-2: Secondary Lithium-Ion Cells – Part 2: Reliability and Abuse Testing
  • ASTM E83: Standard Test Method for Verification of Linear Displacement Measuring Systems
  • ISO 12417-1: Mechanical Testing of Metals – Dilation Test
  • CE Certification(Conformité Européenne)

Product Advantages

  1. Sub-Micron Precision
    • 0.05 μm Resolution: Tracks nanoscale volume changes during rapid charge/discharge cycles.
    • Laser-Based Sensors: Non-contact measurement eliminates mechanical interference.
  2. Multi-Environment Testing
    • -20°C to 150°C Chamber: Simulates extreme climates and thermal abuse scenarios.
    • Pressure Cycling: 0–30 bar dynamic loading for fatigue testing.
  3. Real-Time 3D Imaging
    • Structured Light Scanner: Generates volumetric strain maps at 5 fps.
    • AI-Powered Deformation Analysis: Quantifies anisotropic swelling in cylindrical cells.
  4. High-Throughput Design
    • 4-Channel Parallel Testing: Monitor 4 batteries simultaneously under identical/custom protocols.
    • Auto-Sequence Programming: 50+ preloaded test profiles (fast charging, overcharge, etc.).
  5. Smart Data Integration
    • API Connectivity: Syncs with EIS, thermal cameras, and gas analyzers for holistic diagnostics.
    • Cloud-Based AI: Predicts cycle life based on expansion-voltage coupling.

Product Features

  • Non-Destructive Testing (NDT): Preserves sample integrity with <0.5 N contact force.
  • Laser-Guided Alignment: Ensures precise battery positioning (±2 μm accuracy).
  • Dynamic Strain Calibration: Auto-corrects for thermal drift during long-term testing.
  • Emergency Shutoff: Dual redundant safety circuits with E-stop button.
  • Glovebox Compatibility: Oxygen/moisture levels <0.1 ppm for sensitive chemistries.
