Product Advantages
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.
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.
Real-Time 3D Imaging
Structured Light Scanner: Generates volumetric strain maps at 5 fps.
AI-Powered Deformation Analysis: Quantifies anisotropic swelling in cylindrical cells.
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.).
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.
