Conductive Terminal: Temperature Range -40°C to +125°C

Component Specifications

Definition

A precision-engineered electrical component designed to establish and maintain reliable electrical contact between battery cell tabs and busbars or interconnects in battery modules and packs. It ensures low-resistance current paths while accommodating thermal expansion and mechanical stresses in battery systems.

Working Principle

Operates on the principle of establishing a low-resistance electrical interface through controlled pressure contact between conductive surfaces. The terminal maintains consistent electrical conductivity by minimizing contact resistance through proper material selection, surface finish, and mechanical clamping force, while allowing for thermal expansion differentials between battery cells and connecting elements.

Materials

Copper alloy (C11000 or C10200) with optional silver or tin plating for enhanced conductivity and corrosion resistance. Alternative materials include aluminum alloys (6061-T6) for weight-sensitive applications, with nickel plating for aluminum terminals to prevent galvanic corrosion.

Frequently Asked Questions

What is the primary function of a conductive terminal in battery systems?

The conductive terminal provides a reliable electrical connection between individual battery cell tabs and the system's busbars or interconnects, ensuring efficient current flow with minimal resistance and heat generation.

Why are copper alloys preferred for conductive terminals?

Copper alloys offer excellent electrical conductivity (typically 90-100% IACS), good mechanical strength, and favorable thermal properties, making them ideal for high-current applications in battery systems.

How does plating affect terminal performance?

Plating (tin, silver, or nickel) enhances corrosion resistance, improves solderability, reduces contact resistance, and prevents oxidation that could increase electrical resistance over time.
