Design and manufactureBattery Cell to Cell ConnectionsCELL TO CELL

Cell-to-cell connections are fundamental to battery module performance. They must carry high continuous current, tolerate vibration, accommodate thermal expansion, and maintain low resistance over long service lives.

Tranect designs and manufactures copper cell interconnections engineered for electrical reliability, mechanical durability, and scalable production.

Whether the requirement is prototype development or volume manufacture, we support projects from design clarification through to production delivery.

Battery module interconnects are not just conductors. They must:

• Carry high DC currents with minimal resistive loss
• Maintain stable contact resistance over thousands of thermal cycles
• Withstand vibration and mechanical shock
• Manage differential expansion between cells and busbars
• Integrate with automated assembly processes

Poorly specified connections increase heat generation, accelerate degradation, and introduce reliability risk. Good design eliminates these problems early.

For rigid module architectures, we manufacture:

• CNC-machined copper links
• Pressed and formed busbars
• Drilled and countersunk terminations
• Plated components ready for assembly

Manufactured in C101 and C110 copper grades as standard.

We do not simply supply copper strip cut to shape.

We work with customers to clarify:

• Required continuous and peak current (default design assumption: 2 A/mm² unless otherwise specified)
• Allowable temperature rise
• Connection method (bolted, welded, riveted, brazed)
• Assembly tolerances
• Expected service environment

Where drawings are incomplete, we assist in defining manufacturable solutions that reduce cost and improve robustness.

Early engagement typically reduces redesign cycles and avoids expensive late-stage tooling changes.
