Battery Module Connection Busbar

Product Positioning:

The HTD Battery Pack Internal Busbar serves as the critical backbone for electrical connectivity within modern energy storage systems. Designed for high-voltage applications, this busbar acts as the primary conductive component, efficiently managing current collection and distribution between individual battery cells within a module. We utilize advanced materials, including copper-clad aluminum composites and high-purity copper or aluminum, to strike the perfect balance between superior electrical performance and lightweight design. Each component is manufactured using precision stamping and bending techniques to ensure exacting dimensional tolerances. Furthermore, our specialized insulation processes guarantee reliable isolation, preventing short circuits and enhancing overall safety. By ensuring low resistance and high current-carrying capacity, our Internal Busbars deliver stable, efficient, and safe current transmission, making them essential for optimizing the performance and longevity of your battery packs.

Core Processes & Manufacturing Workflow:
Material Preparation & Forming
  • Composite Material Casting: Uses a core-filled continuous composite casting process where aluminum is injected into a copper shell at 740-760°C, achieving an oxidation-free copper-aluminum composite interface.
  • Precision Stamping & Bending: The busbar structure is formed in a single operation using multi-directional CNC bending equipment, with tolerances controlled within ±0.1mm.

Installation Hole Processing & Treatment
  • Milling & Polishing: Ends are milled for installation holes, polished to remove burrs, and ultrasonically cleaned to ensure no metallic residue.

Insulation Protection Process
  • Heat-Shrink Tubing Wrapping: PE polyethylene heat-shrink tubing covers the main busbar body, shrunk uniformly in a 130-160°C hot air tunnel.
  • Optional Dip Coating Process: Epoxy powder dip coating forms a fully encapsulated insulating layer, resistant to high temperatures and corrosion.
