Mastering Terminal Crimping for Energy Storage Wire Harness
In energy storage systems, wire harnesses serve as the vital link between battery modules, power electronics, and control units. Among all steps in the harness production process, terminal crimping is one of the most critical for ensuring electrical performance, mechanical reliability, and system safety.
At Forman Precision Industry Co., Ltd., we combine years of industry experience with precision engineering to guarantee the highest crimping quality for energy storage connectors and cable assemblies.
🔧 Why Terminal Crimping Matters in Energy Storage Systems
In high-voltage battery systems—especially those rated up to 1500V and 350A—a faulty crimp can result in overheating, electrical failure, or even fire hazards. Proper crimping ensures:
-
Low contact resistance
-
Secure mechanical retention
-
Consistent current flow
-
Long-term vibration resistance
It’s not just about crimping; it’s about precision connectivity for reliable power delivery.
🛠 Key Equipment for Terminal Crimping
Forman uses advanced crimping tools and testing equipment to maintain tight tolerances and repeatable quality. Our crimping process includes:
-
Semi-automatic and fully automatic crimping machines for consistency and speed
-
Crimp height micrometers for precise measurement
-
Pull force testers to verify mechanical strength
-
Color differentiation analyzers for wire position verification
-
Crimp cross-section analyzers for internal quality inspection
These tools ensure each terminal meets both electrical and mechanical performance standards, such as IEC 60512, UL 486, and VDA 19.1 cleanliness requirements.
📌 Best Practices for Crimping Energy Storage Terminals
To guarantee safe and reliable assemblies, our engineers follow strict procedures:
1. Material Matching
Ensure that terminal materials (copper, tinned, or silver-plated) match cable conductor types for optimal conductivity and corrosion resistance.
2. Correct Wire Preparation
Strip length must be exact. Too long and it causes shorts; too short and it reduces contact area.
3. Precise Crimp Die Selection
Each terminal and cable combination requires a specific crimp die and pressure profile for full compatibility.
4. Crimp Height & Width Control
Every crimp is verified with micrometers and test charts to ensure tight dimensional control.
5. Cross-Section Analysis
After crimping, terminals are cut and polished for microscopic examination, confirming proper strand compression and metal flow.
6. Tensile Strength Testing
Every wire-terminal joint is subjected to pull force testing to ensure it withstands mechanical stress during installation and use.
