In today's fiercely competitive global new energy landscape, prismatic cells are emerging as the mainstream choice for power batteries due to their high energy density and superior space utilization. However, the industry still grapples with module-level yield rates below 95%. As a solution provider deeply rooted in intelligent battery equipment, we integrate a "zero-defect" DNA into assembly lines through the following quality control system:

1. Cell Consistency Sorting: Eliminating Safety Risks at the Source

• Dynamic Voltage Grouping Technology: Utilizes high-precision CCS detection systems (±0.1mV) to achieve ≤5mV voltage deviation within groups, eliminating charge/discharge imbalance risks.

• Multi-Dimensional IR Screening: Four-terminal testers ensure ≤0.9mΩ internal resistance deviation, achieving ±0.25% sorting accuracy from 100,000+ cell inventories.

• AI Pre-Matching System: Based on capacity-voltage-IR 3D modeling, predicts cycle degradation curves, improving group compatibility by 40%.

2. Full-Process Laser Welding QC: Micron-Level Penetration Control

• AI-Powered Weld Defect Detection: 3D vision inspection captures cracks/pores (sensitivity ≤50μm) in real time, with automatic defect sorting.

• Closed-Loop Penetration Control: Infrared thermal imaging dynamically adjusts laser power to ensure 100% compliance with 0.5-1.75mm penetration depth.

• X-Ray 100% Coverage: 256 inspection points per module, with welding quality data linked to MES.

3. Dual Insulation Safeguards: Breaking 2000V High-Voltage Barriers

• Dielectric Strength Tests:
  ▶ Module-level: Insulation resistance ≥550MΩ (500VDC)
  ▶ Pack-level: 3820VDC/30s withstand test (leakage current <1mA), exceeding CN standards by 20%.

• Multi-Stage Environmental Simulation: Validates insulation material durability under 85°C/85%RH extreme conditions.

4. Aerospace-Grade Structural Precision: Nanometer Tolerance Control

▶ Micro-strain sensors compensate for thermal expansion in real time, maintaining 99.7% dimensional stability after 1,000 cycles.
